Test command question
Hi all!

I'm new to shell scripting, and I need to do a diff between two dirs. One of them (dir_old) contains many files, and the other (dir_new) contains just a set of 8 files, all starting with MC and extension .CP.

The problem I have is that dir_old contains about 20 files that start with MC and with no extension, so I need to check if the files in dir_new exist before using the diff.

This is what I have so far:

Code:
cd $dir_old
for name in MC*
    do
        if [test -e  $dir_new$name.CP]; then
            diff -s "$name" "$dir_new$name.CP" >> logfile
        fi
    done

Thanks in advance!

DESCRIPTION

       Bzcmp  and  bzdiff  are used to invoke the cmp or the diff program on bzip2 compressed files.  All options specified are passed directly to

       then they are uncompressed if necessary and fed to cmp or diff.	The exit status from cmp or diff is preserved.
