List all files / binaries in current PATH Is there an "easy" way of running an "ls -la" style command for listing all files / executable binaries in the current PATH? (I intend to pipe the output into grep, for looking for commands with unknown prefixes but basically known "names", the kind of case when the auto-completion / tabbing in bash is essentially useless. So some sort of an "inverse auto-complete feature" ...)

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.
