Rio tips and tricks
===================
Filename completion is available with CTRL+F.
Command `"` prints the last used command.
`""` _executes_ the last command.
Both accept an optional argument to match a command string, ie:
term% touch /tmp/1
term% lc /tmp
1
term% "
term% lc /tmp
term% ""
term% lc /tmp
1
term% "" to
term% touch /tmp/1
term% "" l
term% lc /tmp
1
If there is a command you want to run repeatedly, it's easy to define a rc function and use it instead:
fn t { mk && ./6.out some arguments here >log && grep something log }
t
To change the function without having to search it in the window, run `whatis t`, then redefined it.
`ls /env/fn*` will show which functions are defined.
To clear the window from any text run `echo >/dev/text`.
If you need to snarf an output of some command, instead of outputting into the window and then using mouse,
consider doing it directly instead: `command arg arg >/dev/snarf`.
Want to do advanced searching on window's text? Run your favorite text editor on it: `sam /dev/text`.
