Hi, I'm trying to test whether a directory path exists when a file is passed to my script. I use dirname to strip and save the path. I want my script to run only if the path exists. This is my attempt below.

FILE=$1 DIRNAME=dirname $FILE

if [ -z $DIRNAME ] ; then echo "Error no file path" exit 1 fi

But this doesn't work. Actual when there is no file path dirname $FILE still returns "." to DIRNAME, i.e. this directory. So how do i distinguish between "." and "/bla/bla/bla".

Thanks.
