Check if filename is in directory

[omoo]

Hi,

I have 2 directories, 1st dir with actual files and the 2nd dir with files with zero contents. What command in unix can I use to check for every file in 2nd dir, whether there is a matching filename in 1st dir.If no matching, delete it; if yes, go to next file.

For example,
1st dir:
abc.txt
def.zip
ghi.gds.pgp

2nd dir:
xyz.zip
abc.txt
stu.zip
ghi.gds.pgp

The resulting files in 2nd dir shd be:
abc.txt
ghi.gds.pgp

Hi feherke,

I got this error msg when I tried to use your script:

test: argument expected

Hi

Hmm... Try with bracket ( [ ) instead of [tt]type[/tt].

cd dir2
for f in *; do [red][[/red] ! -e "dir1/$f" [red]][/red] && rm "$f"; done

I use Bash 2.05b, and the [tt]test[/tt] I used is a shell builtin. ( The bracket also. ) But works also with [tt]/usr/bin/test[/tt].
