Tips and tricks
Opening URLs from 9front on your phone/tablet
One way to do it is to display a QR code and then scan it:
echo http://some.url.here/blah | qr | resample -x 800% | page
Rio
Filename completion is available with CTRL+F. To go from anywhere back to the command prompt, use CTRL+B.
More information about shortcuts and keys in general is available in rio(1)
and keyboard(6)
.
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
Hint: grep '^term% ' /dev/text
.
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 redefine it.
ls /env/fn*
will show which functions are defined.
To clear the window from any text run >/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
.
Want to take a screenshot of a window, but no idea which id that window has? Try seaching by its label:
grep sam /dev/wsys/*/label
. Replace the label
in the path to window
and take the screenshot:
topng </dev/wsys/X/window >/n/mycoolblog.com/www/files/acme.png
.
Having screen image filled up with some random messages on top of rio? Run window -hide -scroll cat /dev/kprint
in
your riostart
.
When it gets difficult to work with too many windows on the screen, consider running winwatch
and using one
nested rio
per virtual “workspace”. If you’re into keyboard-controlled window managers with virtual
desktops, try out riow.
Random facts
cat input | something >output
or something <input >output
? Prefer the latter as it requires
less resources. It also allows the something
program to use input
as a normal file rather than
a pipe, ie it has random access, while with pipes all it can do is read the file in strictly
sequential order.
