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";

make_sockdfc

MAKE_SOCKDFC(8) 					      System Manager's Manual						   MAKE_SOCKDFC(8)

NAME

       make_sockdfc -  Generates frozen configuratyion file for SOCKS server

SYNOPSIS

       make_sockdfc [infile [outfile] ]

DESCRIPTION

       make_sockdfc reads in a plain-text configuration file for the SOCKS server and produces a frozen configuration file as the output.

       Both  arguments	are  optional. The default for infile is /etc/sockd.conf; the default for outfile is /etc/sockd.fc. You may specify infile
       while omitting outfile, but you cannot specify outfile without also speficying infile.

       The contents of the frozen configuration file is essentially the memory image of the parsed input file. Using the frozen configuration file
       can reduce the start-up delay of the SOCKS server program since it no longer has to parse the file contents.

       When  the  SOCKS  server  starts, it always looks for the frozen configuration file /etc/sockd.fc first. If that file is not found, it then
       tries to use the plain-text configuration file /etc/sockd.conf. If you use frozen configuration, you  must  remember  to  run  make_sockdfc
       every time after you modify the plain-text file or the SOCKS server will continue to use the frozen file of a previous configuration.

       To find out the contents of a frozen configuration file, use dump_sockdfc.

FILES

       /etc/sockd.fc, /etc/sockd.conf

       dump_sockdfc(8), sockd.conf(5), sockd.fc(5)
