sdiff script help

SM_3 — Thu, 22 Dec 2005 13:25:01 GMT

Hello

I need to scripting help, I'm usless at scripting.

I'd like a script that comapres files in 1 directory with another directory.
Would it be possible to port such a script across different unix flavours?

Thanks.

First take a look at "man dircmp" to see if that doesn't do what you want.

Hi:

See the manpages for 'diff'. This will compare and report the differences for files or files within two directories.

Regards!

Hi (again):

If you truly mean 'sdiff' have a look too at its manpages too. Both 'diff' and 'sdiff' are generalized to UNIX.

If you are only looking to compare file names, then maybe the following-

ls /dir1 >/tmp/f1
ls /dir2 >/tmp/f2
comm -23 ; # display names in /dir1 but not /dir2
comm -13 ; # display names in /dir2 but not /dir1

The actual directories have many, many subdirectories.
Will this make a difference, dont have access to the servers right now to try out your suggestions?

thanks

man dircmp

NAME
dircmp - directory comparison

SYNOPSIS
dircmp [-d] [-s] [-wn] dir1 dir2

DESCRIPTION
dircmp examines dir1 and dir2 and generates various tabulated
information about the contents of the directories. Sorted listings of
files that are unique to each directory are generated for all the
options. If no option is entered, a sorted list is output indicating
whether the filenames common to both directories have the same
contents.

-d Compare the contents of files with the same name in both
directories and output a list telling what must be
changed in the two files to bring them into agreement.
The list format is described in diff(1).

-s Suppress messages about identical files.

-wn Change the width of the output line to n characters. The
default width is 72.

HTH,
Art

If you have many servers that are suppose to have the same directory structure and you are looking for discrepencies, then a perl script would provide you the most power. (Assuming you have openssh installed and have configured all your servers).

#!/usr/bin/perl
@servers=qw/moe larry curly/;
foreach $server (@servers) {
open(INP,"ssh $server 'find /yourdir -print|'");
while() {
chomp;
push(@{$hold{$_},$server);
}
close(INP);
}
foreach $dir (sort keys %hold) {
printf "%40s %s\n",$dir,join(",",@{$hold{$dir}});
}

This will list all the files and the servers they reside on. You could modify the script to only display those files that are not on all the servers.
