Hello. I'm trying to creat a "magic GNU cat". It works like this:
Given a file named "myvars" containing:
--BOF--
my name is $USER
my home is at $HOME
--EOF--
then the command should do (e.g):
$ magicat myvars
my name is dudits
my home is at /home/dudits

So far I got here:
--BOF--
#!/usr/bin/perl + $fname = $ARGV[0]; open(FHANDLE, $fname) or die("Error opening file.\n");<br> while(<FHANDLE>) { $_ =~ s/\$([A-Z]+)/\$$1/g; print $_; } close(FHANDLE);
--EOF--
This script prints the variables as it's found in the file, just like GNU cat would do. I need to get the vars "converted" before actually printing it. Any tips or ideas? Thanks in advance.
