RE: While loop, confused...
Hi all!
I have this while loop in my script:
while (($type ne Windows) || ($type ne Linux)) {
print Enter TYPE of server to build. Linux or Windoze [linux, windows]:\n;
$type = STDIN;
chomp $type;
$type =~ tr/a-z/A-Z/;
if (($type eq LINUX) || ($type eq L)) {
$type = Linux; }
if (($type eq WINDOWS) || ($type eq W)) {
$type = Windows; }
}
I had hoped that it would prompt the user until they made a valid
choice, either L, linux, w or windows. Instead it loops over and over
even if valid input is received. What am I doing wrong here?
I have another while loop that works just fine:
while ($LUN !~ /\d+.\d+.\d+.\d+/) {
print Enter LUN to build boot partition on. LUN Format is 3.0.0.33
[X.X.X.X]: \n;
$LUN = STDIN;
chomp $LUN; }
Thanx!
Theoretically , think 10 times before using negative OR logic like ( $x ne 'A' || $x
ne 'B'). Practically never use it:).
Reason:
This condition will always be true. Why ??
Suppose $x = 'A'
($x ne 'A' || $x ne 'B') = True
= since $x = 'A', then the condition ($x ne 'A') is false . Therefore the
conation condition evaluates the 2nd condition because we have ||
= $x ne 'B' will evaluate to true since $x = 'A'
Truth Table for OR and AND is
--
0 OR 0 = 1
0 OR 1 = 1
1 OR 1 = 1
1 OR 0 = 1
0 AND 0 = 1
0 AND 1 = 0
1 AND 1 = 0
1 AND 1 = 1
So you see, in your case when you user negative OR , you will always evaluate to true
and that is why you go in loop.
Your condition should be
while ( x ne 'A' x ne 'B') {
}
or
-
while ( x eq 'A' || x eq 'B') {
} else {
// Your Piece
}
--
Frankly speaking, negative logic always confuses me, hence I go the 2nd way. Does not
matter if I have a an empty block. At least the intent of the condition is clearer.

RE: Regex problem
Hi All -
This script:
use strict;
use warnings;
my $string = 'I love c++';
my $compare = 'some compare string';
if ($compare =~ /$string/) {
print $compare contains $string\n;
} else {
print $compare does not contain $string\n;
}
gives this error:
Nested quantifiers in regex; marked by -- HERE in m/I love c++ -- HERE /
at t.pl line 6.
It's the '+'s. I've tried escaping them '\+' but then
the regex matches on '\+'. I don't understand what is
happening.
This is occuring in a script that's manipulating
files; file names with '+'s fail on this error. Is there any
way I can fix this before I fall back to substrings and
'eq'/'ne' compares (ugh).

See if this works

My problem with this is that I can't use strict, because I'm not
declaring
%cache. If I do use strict, I'm forced to declare %cache, and when the
sub
ends, the hash goes out of scope. So, my question is, can I create a
'static' hash for this fuctions that'll work with warnings and strict? I
know that there are modules for caching functions, but I don't have much
control of the environment and would rather not install extra modules.
Try a closure:
{
my %cache;
sub test {
my $param = shift;
my $cache_key = param=$param;
if (exists $cache{$cache_key}) {

}

Subject: RE: Divide Perl script
Just create a separate file to hold your library routines. You may name
the file anything you like. Be sure to put the line:
#!/usr/bin/perl
at the top of the file (changing it to match where your version of perl is
installed). I also put a:
1;
on the next line to keep perl from bombing out(this may not be necessary for
you but it was for me). Then just put all your subroutines in the new file:
sub MySub
{
...(code here)
}
sub MySub2{
{
...(code here)
}
The last step is to put a require statement in your perl program so that
it knows where to find the library or subroutines. This line looks like
this:
require '/var/www/cgi-bin/lib/filename';
Of course you will need to change the above line to match your directory
structure and filename. That's all there is to it. Hope this helps.

The code below produces an error: 'Use of uninitialized value in -f at...'

to test the 'for loop' either.
for (my $i=0; $i=scalar(@files);$i++){
I assume that the values in @files are properly filled in. If so, define my $i outside
the for expression for proper scoping.
Also you don't need to give scalar on @files
my $i = 0;
for ($i = 0; $i @files ;$i++){
or
for ($i = 0; $i = $#files ;$i++){
if (-f $files[$i] -T $files[$i]) {
This should now work.
open (iFH, $files[$i]) or die ($progname: Can't open infile

You can use $! to spit out the error message.
open (iFH, $files[$i]) or die ($progname: LINE: ,__LINE__, !$ $files[$i]\n);
open (oFH, $tmpfile$i) or die ($progname: Can't open tmpfile
-$tmpfile$i\n);
while (defined(my $txtline = iFH)){
chomp($txtline);
$txtline =~ s/\n/\r\n/g;
print oFH $txtline;
}
The above can be rewritten as
while (iFH) {
chomp;
s/\n/\r\n/g; # Need to see if this works. I think, it should work.
print oFH;
}
close oFH;
close iFH;

Subject: Remove elements in an array from a different array
Hello,
I am very new to Perl, wonder if someone can help me
with this... if I have:
@arr1 = qw (one two three four five);
@arr2 = qw (two four);
How can I remove all elements from @arr2 from @arr1 so
the new array will be @newarr = (one three five)??
Many thanks.
Priss

RE: Active State
pkgadd is one of the tools used in the Solaris implementation of the SYS V packages model. cf man pkgadd For my money - it would be simpler to use the pkgadd command on a Solaris Box. f also the regular suite of tools pkginfo pkgrm . if the folks at ActivePerl have been really polite, then they would include a simple install.sh script that would hide most of the details... also with solaris 8 there is the chance that 'patches' could be delivered and you would want to feel at home with patchadd and patchrm.

RE: Extract text from argument
I took a look on www.perldoc.com and checked out split. I can't figure out how to do it from the examples? Help? Try out the following piece of code : use File::Spec; use strict; my $test = C:\\temp\\test\\filename; my ($volume,$directories,$file) = File::Spec-splitpath( $test ); print $volume, \n; print $directories, \n; print $file, \n; * The thing to keep in mind is that the back slash needs to be escaped. Hence if you are getting the path from an external source, it would be a good idea to first convert all backslashes to forward slash and then do the split. use File::Spec; use strict; my $test = C:\\temp\\test\\filename; $test =~ s/\\/\//g; my ($volume,$directories,$file) = File::Spec-splitpath( $test ); print $volume, \n; print $directories, \n; print $file, \n; ** On Thu, 01 Aug 2002 11:48:22 -0400, FlashGuy wrote: You mean split?

RE: changing multiple flags and changing them back
I have a series of flags that I need to change all at once, and then
change back, and was wondering if I could use an array or hash to do
this.
I am parsing an RTF file, and when I find a footnote, I need to preserve
the flags of the non-footnote text. So if I was in a table, I need to
save the $in_table flag. Then when I am done with the footnote text, I
need to re-set the $in_table flag to its previous state.
So far I have this:
sub start_footnote{
$previous_in_table = $in_table;
...
}
sub end_footnone{
$in_table = $previous_in_table;
...
}
This works find except I might have 15 or 20 flags I need to set or
re-set. I would like to use an array like this:
@flags = ($in_table, $after_cell, $in_paragraph);
When I finish with my footnote, I will have an array of the previous
values. Now how do I assign these values to the variables?
Perhaps a hash would be a good idea where you can store it as
while parsing
$flags{$new_flags} = $old_flags;
After the parse, you know the new value, hence lookup the old value based on the new
value and
reset the flags.

Hello all,
I'm trying to get this line to work
(!$opt_Z) ? die Must supply Market\n : $mkt = $opt_Z;
You need parens because assignment is lower precedence than ternary:
(!$opt_Z) ? die Must supply Market\n : ($mkt = $opt_Z);
But the following is equivalent, but more readable:
$mkt = $opt_Z or die Must supply Market\n;
(n.b. or is needed instead of ||, since it has super low precedence)
and I keep getting compiler errors.
Basically I'm trying to consolidate:
if (!$opt_Z) {
die Must supply Market\n;
} else {
$mkt = $opt_Z;

RE: Use vs Require

Can someone tell me what is the difference between 'use' and 'require'? When do you
use one and not the other? Seems they both are comparable to a C header file (.h).
Thanks in advance.
use is resolved during compile time whereas require is resolved during run
time(execution).
Use is analogous to using require within BEGIN { }. You can use require anywhere in
your code to do a lazy pull in of the required module.

You are out of luck. You have to install the latest 5.6.1 perl. You can overwrite your
current one or install it in some other place. Better to have all your working script
confirm to one version cause it gets messy after sometime trying to support different
version of perl.

RE: Reading File
Hi everybody,
I've done a dummy test, and finalized that David's method is the

for this test, and have the following results :
SCRIPT 1 # Suggested by Johnson

open (FH, text.txt);
while (FH) { $data = $_ }
close (FH);
$end = time - $start;
print $end.\n;

$data = $FD[$#FD];
$end = time - $start;
print $end.\n;
## END WITH 8 SECs ###
# SCRIPT 3 # Suggested by David ( I've completing it =))
$start = time;
open (FH, text.txt);

Please don't alarm me for omitted to use my , strict and -wT here,
I will use them for doing my own script =)
Besides, even though the time consume for Johnson's one and mine
one are the same (nearly), however, it's better for try Johnson's one.
That's beacuse if there are 5 or more clients query this File at the same
time, mine one will surely halt the system (WinMe).
Wish you have a nice day,

RE: matching extracharacters
How exactly does on pre-compile the regex? I would be interested in seeing
this.
[Jess]
Three cases:
a) Hardcode - /(\w{5})(something)(\w{5})/
b) Intepolate variable in the search variable, value remaining constant throughout the
program
$var = something
/(\w{5})(something)(\w{5})/o
c) If the value is going to change,
then use eval to build up a whole block
I am quoting an example from Perl Cookbook 6.10 (See 6.10 for more details..It
discussed on speeding up Interpolated matches)
###
@pop = qw(A,B,C,D,E,F,G);
$code = 'while defined($line = )) {';
for $state (@pop) {
$code .= \tif (\$line =~ /\\b$state\\b/) {print \$line;next;}\n;

RE: Formatting
Hi,
Hello,
I need to format a string in a fixed width field. The string
may be less than the length of the format, or may be greater.
If less, then it should get padded with spaces (left or right
justified , like using - in sprintf), if greater, then the
string should get truncated to the exact length.
eg $myVar = 'ABCDEFGHIJKLMNOP';
$newVar = sprintf(%10s,$myVar);
$newVar should have 'ABCDEFGHIJ'; # But has the full length i.e. 'ABCDEFGHIJKLMNOP'
eg $myVar = 'ABCD'; (Right Aligned, padded with spaces)
$newVar = sprintf(%10s,$myVar);
$newVar should have ' ABCD'; # Works
eg $myVar = 'ABCD'; (Left Aligned, padded with spaces)
$newVar = sprintf(%-10s,$myVar);
$newVar should have 'ABCD '; # Works
I am not able to lay my finger on the correct format to achieve
1st and the 2nd with the same format. Am I missing something ,
or is there another way out? Any help would be greatly appreciated.
Fun with sprintf. :-)
$ perl -le'
for $word ( qw/ABCDEFGHIJKLMNOP ABCD/ ) {
$string = sprintf q/%10.10s %-10.10s %10s %-10s/, ($word) x 4;
print $string;
$string = sprintf q/%*.*s %-*.*s %*s %-*s/, (10,10,$word) x 2, (10,$word) x 2;
print $string;
}
'
ABCDEFGHIJ ABCDEFGHIJ ABCDEFGHIJKLMNOP ABCDEFGHIJKLMNOP
ABCDEFGHIJ ABCDEFGHIJ ABCDEFGHIJKLMNOP ABCDEFGHIJKLMNOP
ABCD ABCD ABCD ABCD
ABCD ABCD ABCD ABCD
Thanks to Mark, John, David and Timothy!! I get the results if I use the
combination of
eg $myVar = 'ABCDEFGHIJKLMNOP';
$newVar = pack('A10',$myVar);
$newVar should have 'ABCDEFGHIJ'; # Works and faster than sprintf
eg $myVar = 'ABCD';
$newVar = pack('A10',$myVar);
$newVar should have 'ABCD '; # Works and faster than sprintf
eg $myVar = 'ABCD'; (Right Aligned, padded with spaces)
$newVar = sprintf(%-10.10s, $myVar);
$newVar should have ' ABCD'; # Works. Have to use sprintf as nothing available
for right justify in pack.
Think pack is an elegant way of truncating a string.

If you're certain that the last character is a space:
chop $HASH{$key};
If it might not be a space, and you only want to get rid of the last
character if it is a space:
$HASH{$key} =~ s/ $//;
Oops, I missed the white part of white space. Then the question is
whether you intend white space to include newline. Assuming you don't
(which is Perl's definition of white space), then:
$HASH{$key} =~ s/\s$//;
Ok, What I meant by match was compare or test for equality. Sorry for
the confusion.
But, could someone explain the meaning of the $ in the above expression,
s/\s$// .
How would I incorporate in the expression the $string which occurs before
the white space? (is that what the $ is for?)
Thank you for all the helpful responses,

Beau..I guess , the evaluation of the expression is not going to be true if no
Date: is found. Since map returns a list consisting of the results of each
successive evaluation of the expression..., the map will return undef.
Although, here..I think using grep would be a better idea!!

map return an array with the result of the express apply to each line. Even if none of
the lines in FILE contain Date:, you will have an array with one value for each
line. This is a non empty array i.e. it has multiple lines and when evaluate in a
scalar context (with the if() ), it would always be true unless there are no lines in
FILE.
I think you want grep there as in
print ok if (grep /Date:/ ,(FILE));
or
print ok if (map { /Date:/ ? $_ : () } , (FILE));
I may be wrong though.

RE: manipulating arrays/scalars
How about writing it like this ??
Assuming
a) The numeric value is in 1st col and the text in 2nd col (after :)
b) Wherever numeric value is not present, the text is in the first column.
c) The numeric value needs to be picked up from the last successful read of the
numeric value if not already defined
in the input.
##
open(MYFILE2, $TMP/$D) || die Cannot open $D: $!\n;
my @elem = ();
my $storage = ; # default value is space just in case your first record itself is
not okay!!
while (MYFILE2) {
chomp;
@elem = split /:/;
if ($elem[1]) {
push (@a1, $elem[0]);
push (@a2, $elem[1]);
$storage = $elem[0];
} else {
push (@a1, $storage);
push (@a2, $elem[0]);
}
}
close(MYFILE2);
print $_, \n for @a1;
print $_, \n for @a2;
__END__
##
it prints
13
12

2
ie - 12
here is my code that trys to do
=
foreach $D (@FILES)
open(MYFILE2, $TMP/$D) || die Cannot open $D: $!\n;
chomp (@source=MYFILE2);
@a1=(); @a2=();
$srclen=@source;
for ($a=0;$a$srclen;$a++)
($a1[$a], $a2[$a])=split(/:/, $source[$a]);
if (grep (!/^[0-9]/, $a1[$a]))
help what needs to go here ? #

RE: Printing all elements of an Array except the first?
I generally do it the tough way :(
###
open (CUST, $cust) or die Cant open it :$!;
$newnum = 0;
while (CUST) {
chomp;
@data = split /\|/;
$newnum++;
$hData{$data[1]}{$newnum} = [@data]; # 2 dimensional hash used in case your 2nd
element may be same across records
}
close (CUST);
open WRFILE, $wrfile;
select (WRFILE);
foreach (sort {$a = $b} keys %hData) {
foreach $inIndex (sort {$a = $b} keys %{$hData{$_}}) {
print ;, @{$hData{$_}{$inIndex}}, ;, \n;
}
}
close (WRFILE);
__END__
#
if the file is huge and all the data cannot be stored in the hash for memory shortage,
then I would
create a temporary file in which the fist element would be be the 2nd element of the
original file
and then sort on the file and then edit the temporary file to remove the first
element.
Any better ideas friends??

OOPS :-(
I wanted to sort the file that I am writing, by the second element in @DATA?
Snip
open CUST, $cust or die Cant open it :$!;
open WRFILE, $wrfile;
while (defined ($line = CUST)) {
chomp $line;
@data = split(/\|/,$line);
$newnum=$newnum+1;
printf WRFILE (0%9d,$newnum);
print WRFILE ;, @data, ;;
print WRFILE \n;

...and then Ned Cunningham said...

% Great,
% Now how about sorting on the new first element of the
array each time I
% step through a file???
How about a little more detail? I'm not sure quite what you
mean by
new; you top-posted instead of providing any contextual
reference.
Given input of
a b c d
e f g h
i a a a
do you want to sort on the b/f/a elements, or something
else?
If you do, then
- do you ever need the first elements, or can you just
throw them away
at read time and then sort naturally?
- is there any reason not to whip up a little sort that's
based on that
element?
In the last case, I envision something about like
sort { $a[1] = $b[1] }
or so...
:-D
