Hi Aleksey.
If you want to determine whether a shell command is a builtin or a
function, you can use the type command. For example 'type for' or 'type
-t psub'.
If you want to get help to stdout without using a web browser or a
pager, this is done easily enough:
man -P cat for
man -P "" for
man -Tascii if
man -Tlatin1 else
man -Tutf8 psub
Any of these can be made into a function (like an alias in bash) to make
them shorter. For example:
function hlp
man -P "" $argv
end
