Hi Everybody,
I have a script where I need to replace 45 in the beginning, with nothing in a
variable
It looks like this:
#!/usr/bin/perl
$modtager = 45247;
$modtager =~s/45//;
Then $modtager is 247, but if forinstance the number is 4545247, it should
return 45247, how do I do this ?

unless you use this syntax :

only the first occurence of the searched string will be replace...
so what you wrote should work fine...

What's the rationale for hardwiring the Perl executable pathname into
the Perl interpreter? It is some oddity to guarantee Perl can find its

Use File::Find to iterate over the files and then sum up the
newlines you find in each file. Counting the newlines in a
single file is

Be careful with this one. The documentation for it makes it sound like
it's a good idea to set this but doing so turns buffering OFF, not ON.
Normally you leave this alone, even for pipes and sockets; Perl does the
right thing in almost every case.
See:
I can see one problem off the top of my head. You aren't using chomp() on the
line, so $view_path probably has something like e:\\cme\\abc.vws\n in it.

I'm not sure what you mean by refer to, but you can
find the caller's name with the perl caller function. You
can find a practical example of its use here.

True. But since the OP said 'mail' I assumed that meant more than one

You're creating a typeglob *in and declaring it to be local. I'm not
sure why you would want to do this, but this makes $in, @in, and %in all

No.
Perl has two kinds of scoping: lexical and dynamic. Lexical scoping
means the name only has meaning with the block, or if outside any block,
