Hewlett,
If you are on a *nix system try:
a2ps -E -g -n script.pl
This will print line numbers two pages per page with highlight formatting.
Very nice.

Read the error carefully, it may have been giving you a line number in the
Time::Local module in your script, and it will tell you that. Often you
will get the line in the module that had the error as well as the line
number in your script that called the subroutine in the module.

You could even do that in a one-liner:
$ perl -pe'printf("%03i : ", $.)'
Seems a good example of how every little question has some merit. You just

The only line that is not working is
system( rm -rf $file );
The error message is:
Can't call method "rm" with a package or object reference.
Any tips?

Hi,
I am able to install Perl 5.6.1 on my solaris box, but cannot get it to
include SuidPerl in the installation.
Do I have to enable something in the ""Configure"" script?
""d_dosuid"" maybe?
Or is it something to do with SUID in my Solaris Kernel that I need to
enable or disable.
Am not sure.
Rob,
Thank you for the quick reply on the line numbers.
You were right - the line number in the error message was in one of the "use
xxx" modules.
And my face is slightly red from embarrassment re the "how can line numbers
be displayed": Your reply about using a different editor sent me to

I am a total beginner to perl. I wrote the program below to open a program
file, read it line by line, and write each line to an output file after
first putting two string lines out there. It compiles without errors but the
output is a filename with zero length. What did I do wrong? Thank you!

Randy,
You can delete a file, or a list of files, using "unlink". Example:
##
unlink $file;
##
perldoc -f unlink
Hope that helps.

Try 'system("rm", "-rf", $file)'. The quotes are not really
necessary here (I think), but you should use them, because otherwise
"rm" and "rf" will be interpreted as barewords, and you might get in
conflict with the reserved ones.

You (or they) have forgotten the quotes:
system("rm -rf $file");
But if you copied this from another source, that source was totally
unaware that deletion of files like THAT is TOTALLY unsafe.
