Command-Shift-3 (whole screen) and Command-Shift-4 (portion of screen)
will create "Picture x" (x is 1 to whatever). Because of better
features and control, I prefer
Voila has even
Preview also offers screen capture - it's down at the bottom of the File menu.
For a movie of your screen actions, try Jing (also available for Windows).
To capture X screens, the "xwd" program is simple to use. Open
an xterm, type "xwd > file" and (after pressing ENTER), just
click on the window you want to capture. You can also specify a windo with "xwd -id wid", where "wid" is the resource id to be selected. The resulting file can be
printed using "xpr" or manipulated by graphic programs like "Gimp"
and others if you need to save it as .gif or some other format.
For KDE, there is KSnapshot and gnome-screenshot for Gnome. Both also
recognize the PRT-SCRN key
To record screen actions on Linux, try RecordMyDesktop, a "desktop session recorder".
For a "user friendly" OS, Windows has had really awful screen
capture in the past. You press PRT-SCRN, which appears to do nothing.
You then have to open a program like Microsoft Paint, hit CTRL-V
to paste in the shot, and then you can do whatever you want with it.
Vista and Win 7 have "Snipping Tool", which is supposedly much
better (but I've never used it).
No idea where I got this from, it's pretty old
(Xenix days). Works only on the console.
# Shell script to screen dump
# This will only work at present on the main console
stty -echo ixon ixoff -ixany
head -25 > /tmp/screen.$$
# Ok now output the file to the printer
echo "\f" >>/tmp/screen.$$
W/r to Melvin's comment about the escape sequence, man screen and see:
MC (Media Copy) CSI p1 i ps mc0
Causes all or part of the screen to
be sent to the pass-through printer.
Parameter p1 indicates how much of
the screen to send to the printer.
Currently, only p1=2 is supported,
which sends the entire screen
contents. Future versions of scoansi
may support other values.
