Is there a Linux command that will list all available commands and aliases for this terminal session?
As if you typed 'a' and pressed tab, but for every letter of the alphabet. Or running 'alias' but also returning commands.
Why? I'd like to run the following and see if a command is available:
ListAllCommands | grep searchstr
You can use the bash(1) built-in compgen
compgen -c
will list all the commands you could run.compgen -a
will list all the aliases you could run.compgen -b
will list all the built-ins you could run.compgen -k
will list all the keywords you could run.compgen -A function
will list all the functions you could run.compgen -A function -abck
will list all the above in one go.Check the man page for other completions you can generate.
To directly answer your question:
compgen -ac | grep searchstr
should do what yout want.
