Listing commands in Linux

It's a tips basically.
You can list quite a number of linux commands, as well as some utilities by a command named 'compgen'
try this things... and then apply 'man' on them.

1. "compgen -c" will list all the commands you could run.
2. "compgen -a" will list all the aliases you could run.
3. "compgen -b" will list all the built-ins you could run.
4. "compgen -k" will list all the keywords you could run.
5. "compgen -A function" will list all the functions you could run.
6. "compgen -A function -abck" will list all the above in one go.


I think this should eliminate the overhead of cramming the commands. Just remember this, it remembers for you.
