Check file permissions

[scottpeter]

I need to check the permissions on a file or a directory. If I have read/write access I want to process that file/files in the directory.

Case I do not have either of these accesses, give a message that the file does not have required privileges and cannot be processed.

Can somebody please tell me how to do this in shell script.

Thanks,
Scott

man test
if [ -w /path/to/file]; then
# process that file
else
echo "the file does not have required privileges and cannot be processed"
fi

PHV,

That was cool.

Just out of curiosity. How can I check for rw,rx or rwx permissions and print the same message.

Thanks,
Scott

Have you read the man page ?

Oops, I missed the man test part.

However I checked the man page for test. It gives only for
r,w,x,d... etc.

It does not give help for rw/rx or rwx.

Thanks,

Sorry for being stupid and not reading the man properly.

I got it now.

Thanks,
