it is not.
Telcontar:~ # tpipe
If 'tpipe' is not a typo you can use command-not-found to lookup the
package that contains it, like this:
cnf tpipe
Telcontar:~ # cnf tpipe
tpipe: command not found
Telcontar:~ # opi tpipe
Searching repos for: tpipe
1. inputpipe
2. socketpipe
3. inputpipe-debuginfo
4. socketpipe-debuginfo
5. inputpipe-debugsource
6. socketpipe-debugsource
Pick a number (0 to quit): 0

I like my way, it is mine :-)
