Print the PATH directories in the readable format

echo $PATH| awk -v RS=":" '{ print $0 }'

echo $LD_LIBRARY_PATH |awk -v RS=":" '{ system ( "ls -rltd " $0 ) }'

As far as the option ‘-v’ is used, the new awk(nawk in some systems) should be used.

To check if the new version of awk is installed:

awk 1 /dev/null

The output will be empty for new awk.
You have the old awk, if the output is something like

awk: syntax error near line 1

In this case nawk should be used instead awk

MS-DOS modification: echo %PATH% | awk -v RS=”;” “{ print $0 }”
