Hi All,
Currently IF you want to list only the directories ( as a ls command )
or only interested in the directory structure ( tree ),
There is no option in ls.
"ls" has to be enhanced with some "e" flag so that the following
scenarios are supported.
1. This listing has to be based on file types.
2. One or more types can be combined in the option.
eg.
ls -ed would list only directories in the current dir.
ls -edR will list only the directory tree.
ls -el links only
ls -elR links in all sub dir staring with curr dir.
ls -eb block devices
ls -ec char devices...
ls -ep pipe
ls -edlp directories, links and pipes only
etc.
This has been a requirement for a very long time but still not attended
for the past 30 years.
Thanks and Regards,
N.Rajeaswar
