245242 sysdetails.txt

245243 tat - display file or filesystem status

976527 test

245273 testscript.sh

245275 uptime.txt

245276 ystem disk space usage

The following are some of the flags and arguments that can be used with the rm command:

Remove (unlink) the FILE(s).

-d, --directory unlink FILE, even if it is a non-empty directory

(super-user only; this works only if your system

supports `unlink' for nonempty directories)

-f, --force ignore nonexistent files, never prompt

-i, --interactive prompt before any removal

--no-preserve-root do not treat `/' specially (the default)

--preserve-root fail to operate recursively on `/'

-r, -R, --recursive remove the contents of directories recursively

-v, --verbose explain what is being done

--help display this help and exit

--version output version information and exit

Note: if you use rm to remove a file, it is possible to recover the contents of that file. If you want more assurance that the contents are truly unrecoverable, consider using shred.
