Not sure what you are saying, just list what you want. If you only want the name of the directory, add "-d".

$ ll subdirectory

>2. to find out total size (KB/MB) for a specific file, eg: to find out total size for *.t files

Use awk:
$ ll *.t | awk '{ total+=$5 } END { print "Total MB:", total/1000000 }'

Of course you may want (1024*1024) for MB.

Hi ng,

Hi ng,

Try ls -l | egrep '^d', to get a list of subdirectories in a folder.

No real reason to use egrep when grep will do.
