Here is the command to test that all the directories in your path actually exist.

(<a class="zem_slink freebase/en/internal_field_separator" title="Internal field separator" rel="wikipedia" href="http://en.wikipedia.org/wiki/Internal_field_separator">IFS=:;for p in $PATH; do test -d $p || echo $p; done)

And the explanation :

Set the IFS to &#8221;:&#8221;

now we loop through the PATH variable

and test all the directories with &#8221;test -d&#8221;

Here is another version without IFS:

for i in ${PATH//:/ };do test  -d $i || echo $i;done

and next one without the test command:

for i in ${PATH//:/ };do [  -d $i ] || echo $i;done
