The rm command

The rm command deletes files in a directory

The rm command will usually not produce an output unless you have made an error.

There is no "undelete" command in UNIX, once you delete a file, it is gone (unless it is on a backup tape).

Because of this, the rm command on CMGM and PMGM will ask you if you really want to delete a file before it goes ahead and does it.

Most UNIX commands have a variety of additional command modifiers that can be used to change the output. For example, if you typed

rm -r *

you would delete recursively the contents of a directory. This means the contents of a directory and all directories and files under it.

Other popular rm commands include

What to Type	What it Does
`rm *`	delete everything in a subdirectory
`rm *.txt`	remove only files with a .txt on the end
`rm data*`	remove only files that start with the word "data"
`rm -r dir2`	removes everything in the subdirectory "dir2"
