1) Tab conclusion :

A large convenience. If you are keying a command, you require just type sufficient of the command to give a first sector that can just be expanded in a solitary means and afterwards can push TAB as soon as to expand your first sector to the whole command. So, as an example, on my system umo TAB increases to umount. (On my system as what first sectors are extendable just in one means is a function of what you have actually mounted, etc) If you do not type adequate to make the conclusion distinct, TAB will certainly not expand, yet a 2nd TAB will certainly present a checklist of feasible conclusions. So, on my system, um TAB TAB returns :

umask       umax_pp     umount      umount.hal
.

Tab conclusion additionally works with courses : cd /home/me/docs/reallylo TAB will, if one-of-a-kind, expand to cd /home/me/docs/reallylongdirname and also, otherwise one-of-a-kind, supply a checklist of prospect extensions similar to um over.

2) man some-command or some-command --help or some-command -h :

If you can not remember just how a command functions, you can get documentation right there in the shell. man generally gives one of the most information. Generally one or both of the --help and also -h debates to a command gives a brief recap.

3) head :

man some-command takes control of the incurable and also stops you from getting in commands while the man message is presented. man some-command | head will certainly present the first 10 lines. man some-command | head -n will certainly present the first n lines. In both instances, you get your punctual back, to make sure that you can have the man message on screen as you enter your command.
