ls -1 /tmp/dir1 > list1
ls -1 /tmp/dir2 > list2

grep -f list1 list2 > common_files

Hi,
Vibhor solution looks much easy to use.
Just to put it in script e.g. "script1":

----------------------------
#!/usr/bin/ksh
ls -1 /tmp/dir1 > list1
ls -1 /tmp/dir2 > list2
grep -f list1 list2
-----------------------------

# chmod +x script1
# ./script1 dir1 dir2

Sorry for multiple post ...but change mising in cut paste :)

----------------------------
#!/usr/bin/ksh
ls -1 $1 > list1
ls -1 $2 > list2
grep -f list1 list2
-----------------------------

Hi,

You can also use dircmp(1)
it will give you 2 lists:

1: a list of files that only exist in either dir1 or dir2

2: a list of files which exist in both dirs

Also it compares the files and will tell you if the files are different or the same

Cheers

You can do as,

1) diff -s /tmp/dir1 /tmp/dir2 | grep 'identical'

2) dircmp /tmp/test1 /tmp/test2 | grep 'same'

hth.
