Hi,
If you are using Unix, for a one off operation you should
be using the sed program... like this:
sed s/pattern/replacement/g
It takes standard in, and puts its output on standard out.
I normally use it like:
cat FILE | sed s/pattern/replacement/g > OUTPUT
However, the perl solution is fairly simple and of course
can be expanded easily. Here is how I would do it:
--- SCRIPT ---
#!/usr/bin/perl -w
use strict;
my $filename = shift;
open (FILE, $filename) or die "Canīt open file: $!";
while ( <FILE> ) {
s/$pattern/$replacement/;
print;
}
close FILE or die "Can't close file: $!";
--- END SCRIPT ---
I haven't tested it, but it *should* do what you want.
In your script you should use =~. This is a single
operator, whilst = ~ is two operators... doing something
completely different.
Also, where does the loop take the input, and assign it to
the variable you do that pattern match on?
Take care,
Jonathan Paton
