What command string did you use? sed -e 's/!/:/g' mygroup|sort|sort -n -k 3 -t : > newgroup 8. Consider the following alias: > > alias dirc 'ls -l | grep '^d' | wc -l' > > A. What EXACTLY will this alias do when it is executed? It will return the number of subdirectorys of the directory from which this command is started. > 4. cd to the directory called final that is located within my home > directory.

If there is no file which is larger then an directory entry, then you get a directory name as the result. But I guess that's correct because in Unix EVERYTHING is a file... :) Hope this will help you! kind regards, Stephan
