handy with unix and unix scripting, however, I'm terrible at perl.
What I'm looking to do with a perl script is the equivalent of the
following unix (bash) script:
cat tempfile1 | sort > newfile2; rm tempfile1
I'm not completely comfortable with file handling in perl, and I think
it should be easy to do, but I've been unsuccessful in trying to do it.
Post what you've tried.
I'm essentially trying to sort the lines in a file (alphabetically),
and then output them to another file.
I guess I should have said that I don't want to handle this with a
system call either, I'd prefer to figure out, and learn how to do it
with purely perl.
If you want to figure it out, give the documentation a try.
perldoc -f open
perldoc -f sort
perldoc -f unlink
perldoc opentut
