script to check $PATH directories exist
 
Is there a script that i can use to check if the directories in $PATH exist?

try this

Code:
#!/bin/sh
IFS=:
read dirs <<END
$PATH
END
for dir in $dirs
do
 if [ ! -e "$dir" ]
 then
  echo "$dir does not exist."
 else
  echo "$dir  exist."
 fi
done

This 'one liner' can do that for you:

for THIS_PATH in `echo $PATH | sed 's/:/ /g'`; do [[ ! -d $THIS_PATH ]] && echo "WARNING $THIS_PATH does not exist."; done

The scripted form would look like this:

Code:
#!/bin/bash
for THIS_PATH in `echo $PATH | sed 's/:/ /g'`
do
  [[ ! -d $THIS_PATH ]] && echo "WARNING $THIS_PATH does not exist."
done
Hope this helps.

This one-liner would suffice for me:

ls -d `echo $PATH|tr : ' '`

Notice how you can also check $? to see if they all exist (ls returns 0 if all went well, 1 if there's an error).
