Some quick googling didn't find any hits for a similar thing for systems administration, so I'm starting one.
I need your help; interested in contributing ideas or content? Email me jls-sa@semicomplete.com.
I just finished working on the xinerama portion of multi-screen support for keynav.
If someone is interested, I could use some help testing. It's working for me, and there are a few odd behaviors that I'm not sure are the best. Let me know if you test it.
No new official release yet, but if you want to test, svn can be
fetched with:
svn checkout http://semicomplete.googlecode.com/svn/keynav
- Include support for multiple screens.
* When 'start' happens, the region will be the size of the current display
(wherever the mouse is)
* Moving the region outside of the current display will move it to the next
display (right or left). This currently only works with Xinerama.
* History works as expected (move to the right display, history-back goes to
the previous display, etc)
* When multiple Screen (non-xinerama) are found, XGrabKey on all root windows.
* Screens are sorted, if possible, from left-to-right based on x-coordinate
origin. This unfortuntely means, for now, only left-to-right monitor
configurations are known to be supported.
20080522:
- Sync xdotool library to 20080521.
- Added 2 grid examples to keynavrc
- Applied patches from Richard Kolkovich
+ Fix backwards math when calculating Nth cell when using 'cell-select N'
+ Fix dislexia when doing 'cell-select NxM'
+ Abort update() calls when app is inactive.
- Now warns you if you try to execute an invalid command.
(Yes, 0522 is tomorrow. Turns out uploads to googlecode are write-once, so I'll
need to come up with an additional versioning scheme that lets me push multiple
releases in a single day in case I find something bad after I upload a
release.)
20080521:
* Import patches from keynav's xdotool branch (From Lukas Mai) which make
xdotool compile happily when building with -Wall and -pedantic (and others)
* Finally convert to using Window type for (hopefully) everything instead of
incorrectly typecasting Window to int sometimes.
* Confirmed that the one (but mostly useless) test passes.

Changelist:
20071119 -
- Add nongreedy tokenizer. Same semantics of strtok_r(), but doesn't skip
empty tokens.
- Renamed tokenizer to split, since really that's what it was doing.
- You can invoke the nongreedy tokenizer by using '?' as the first character
of a {} set:
args: :{?4,6}
input: one:::four::six
output: four:six
Changelist:
20071026 - First major release
- Added some tests
- If you want to specify a different first split token, the first character
can be any non-digit character which is not '-' or '{'.
These are now equivalent:
% echo "foo/bar/baz" | fex 0/2
bar
% echo "foo/bar/baz" | fex /2
bar
Previously, this would give an error due to a design decision.
File: 'connect.over' contains
#include <netinet/in.h>
override(`connect', `
{
// code to inject before the connect() call is actually made
}
')
Output is 'connect.so' which overrides libc's connect function.

The strange ssh connection on fd=4 above is seemingly due to ssh calling connect() on a tty? fstat says:
jls ssh 3221 4 /dev 122 crw--w---- ttypd rwinode 122 on /dev is /dev/ttypd.
