Write a shell script checkpath that extracts each directory from the user's PATH and ensures that the directory exists and is readable. Report either error condition or confirm that the directory is correctly configured. Hint: directories in the PATH are separated by a colon (:).

Question

What will be an ideal response?

Answer 1

for directory in $( echo $PATH | sed 's/:/ /g')
do
if [ ! -d "$directory" ] ; then
echo "Warning: PATH directory $directory doesn't exist"
elif [ ! -r "$directory" ] ; then
echo "Warning: PATH directory $directory isn't readable"
else
echo "Checked directory $directory"
fi
done

exit 0
