Full Discussion: for i in `cat file` do

If you want to preserve the input file content intact
during processing you should be using something like
this:

Code:
while IFS= read -r var; do
  printf '%s\n' "$var"
done < infile

Consider the following:

Code:
bash-2.03$ ls
infile
bash-2.03$ cat infile
one two
-n -e ok?

   three *
bash-2.03$ for i in `cat infile` ; do   echo $i    ; done
one
two

ok?
three
infile
bash-2.03$


And:

Code:
bash-2.03$ while IFS= read -r var; do   printf '%s\n' "$var"; done < infile
one two
-n -e ok?

   three *
bash-2.03$

So the later with Perl would be:

Code:
bash-2.03$ perl -pe1  infile
one two
-n -e ok?

   three *

Or:

Code:
#!/usr/bin/perl

use warnings;
use strict;

open my $infile, '<', 'infile'
  or die "open: $!\n";
  
print while <$infile>;

close $infile
  or warn "close: $!\n";
