Filename search using Shell Script -

i trying search set of files same name between 2 directories

**dir1** (/myfolder/sample/test1)                      file1.txt                    file2.txt                    file3.txt file4.txt  **dir2** (/myfolder/sample/test2) file1.txt file4.txt 

i using diff command in following way

diff -sr /myfolder/sample/test1/ /myfolder/sample/test2/ | awk -f: '{print $1}' | grep -r ".txt" 

the result follows:

files /myfolder/sample/test1/file1.txt , /myfolder/sample/test2/file1.txt identical files /myfolder/sample/test1/file4.txt , /myfolder/sample/test2/file4.txt identical 

the result looking file name:

file1.txt file4.txt 

any appreciated!!

a little fiddling ls & grep should work too:

ls dir1 | grep "`ls dir2`" 

or, if it's c shell:

ls dir1 | grep -e "`ls dir2 | tr '\n' '|'` " 

as observed radical7, first method wouldn't work in c shell, newlines lost while passing grep. such cases use regex, instead.

grep -e or egrep allows use regex of form file1.txt|file2.txt pattern.

also, note whitespace @ end intentional.
