tar -czf ./file.tgz ./*

edit: i do hope that is correct without checking :-)

So the dash in `-czf` if optional? Which reminds me: why does ps have two sets of options again?

Don't laugh, it's actually three sets of options now:

- UNIX options, which may be grouped and must be preceded by a dash.

- BSD options, which may be grouped and must not be used with a dash.

- GNU long options, which are preceded by two dashes.
