PERL Scripting: Diff 2 files and save output to file3
Hi,

I need to create a script to compare 2 files and store the output in a 3rd file.
This is how I do manually, but since I need to do this for about 150 files every week, I am trying to automate it using perl.
diff -u file1 file2 > file3.patch

For my script,

- I have 2 files under different file paths, say
$gpath = $WS_GOOGLE_COMPARE . $_;
$lpath = $WS_LOCAL . $_;

- I want to diff these files in 2 different paths and store the output in a 3rd file path location, say /home/diff.patch (this is a third path location)

Please help.

zcmp

ZDIFF(1)						      General Commands Manual							  ZDIFF(1)

NAME

       zcmp, zdiff - compare compressed files

SYNOPSIS

       zcmp [ cmp_options ] file1 [ file2 ]
       zdiff [ diff_options ] file1 [ file2 ]

DESCRIPTION

       Zcmp  and  zdiff are used to invoke the cmp or the diff program on files compressed via gzip.  All options specified are passed directly to
       cmp or diff.  If only file1 is specified, it is compared to the uncompressed contents of file1.gz.  If two files are specified, their  con-
       tents  (uncompressed  if  necessary)  are  fed to cmp or diff.  The input files are not modified.  The exit status from cmp or diff is pre-
       served.

SEE ALSO

       cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1)

BUGS

       Messages from the cmp or diff programs may refer to file names such as "-" instead of to the file names specified.
