How can you be so sure it didnt do the sort? Read carefully the man pages of sort again... sort <filename> will not replace your file by a new one sith sorted lines... clue: Quote: sort(1) sort(1) -o output The argument given is the name of an output file to use instead of the standard output. This file can be the same as one of the input files. Where do you think the sort went in your command?

The "find" is probably not hung. It will take time to search from root down. The error messages "find: cannot open" are because you are not logged in as "root" and do not have permission look at some directories. This is harmless because you could not have created a file in one of those directories. If you really don't know where you created the file, the find from root will find it...

i have this basic line of code that accepts for an input parameter.
