3.2.11: rm - remove files

SYNOPSYS:

rm file1 [file2 ... fileN]

DESCRIPTION:

This command deletes a name from the filesystem. If the specified file name was the last link to a file and there are no open file descriptor references to that file, then it is deleted and the associated space in the file system is made available for subsequent use.

If the filename specified was the last link to a file but there are open file descriptor references to it, then the file will remain in existence until the last file descriptor referencing it is closed.

EXIT STATUS:

This command returns 0 on success and non-zero if an error is encountered.

NOTES:

NONE
