All,
I am trying to run logic that will copy/delete 3
versions of log.\d+ files to their respective
directories. Because there are so many directories, I
have built a hash table instead of using a bunch of
"if else conditions" with reg exps.
[...]
So instead of doing the code below because the subdirs
are unique but all log file names are the same,
log.\d+, I want
to use a hash table to decide what log files to copy
where based on the subdir names or the key/value
relationship.
if (@NBlogs2) {
for my $log(@NBlogs2) {
if ($log =~ 'bpcd') {
qx(cp $log $oldir/bpcd/);
}
elsif ($log =~ 'bpdbm') {
qx(cp $log $oldir/bpdbm);
}
elsif ($log =~ 'bptm') {
qx(cp $log $oldir/bptm);
}
}
}
This was the only code in your post that I was able to
understand because I wasn't able to figure out what
words_to_num() was supposed to do. Here are two ways to go
about something like what you want to do:
################################
# This is ultra-simple and doesn't do
# what you want.
if (@NBlogs2) {
for my $log (@NBlogs2) {
if ($log =~ m{([[:alpha:]]+)/log.\d+}) {
my $word = $1;
qx(echo cp $log $oldir/$word);
}
}
}
################################
# This might come closer to what you want.
foreach my $log (@NBlogs2) {
if ($log =~ m{([[:alpha:]]+)/log.\d+}) {
my $word = $1;
my $number = $subdir_for{$word};
qx(echo cp $log $oldir/$number);
}
}
I decided to echo the command rather than to execute it. ALL
CODE UNTESTED.
thank you
