-W, --verify

Check archive for corruption after creation.

-X file, --exclude-from file

Consult file for list of files to exclude.

-Z, --compress, --uncompress

Compress files with compress before archiving them, or

uncompress them with uncompress before extracting them.

Examples

Create an archive of /bin and /usr/bin (c), show the command

working (v), and store on the tape in /dev/rmt0:

tar cvf /dev/rmt0 /bin /usr/bin

List the tape’s contents in a format like ls -l:

tar tvf /dev/rmt0

Extract the /bin directory:

tar xvf /dev/rmt0 /bin

Create an archive of the current directory and store it in a file

backup.tar:

tar cvf - `find . -print` > backup.tar

(The - tells tar to store the archive on standard output, which is

then redirected.)

Filter an archive through gzip, extracting the contents but leaving

the original file compressed:

tar xvfz chapters.tar.gz

taskset

taskset [options] [mask | list] [pid | command [args]]

taskset is used to retrieve or set the processor affinity mask of

either an existing process, given its PID, or to run a new a process,

given its command name, with a specified affinity mask. The Linux

scheduler will then honor the given affinity mask, ensuring that the

process in question runs only on allowed processors.

Options

-c, --cpu-list

The affinity mask
