UNIX for Dummies Questions & Answers

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!

Code:

cd $dir_old
dir_new=/some/new/path
for name in MC*
    do
        if [ test -e  ${dir_new}/${name}.CP  ]; then
            diff -s "$name" "${dir_new}/${name}.CP" >> logfile
        fi
    done

I'm not sure about the .CP - you get to fix that. Are there files minus the CP in dir_old, but that have .CP in newdir? That is what your code is doing.
