The terminfo database is at /usr/share/terminfo/, although you can pick up
files from elsewhere using $TERMINFO or $TERMINFO_DIRS. You can also create an
alternate database at $HOME/.terminfo/. This database consists of a separate
file for each terminal type. You can see your terminal type in the $TERM
variable. Each file is in binary format, but you can print the capabilities in
text with infocmp(1M). Just say, "infocmp xterm" and you get all the
capabilities for xterms. To compile a binary file from a text file, use
tic(1M). The terminfo(5) man page explains what all the different capability
codes mean. Here a few of the capabilities for xterms:
setaf=\\E[3%p1%dm # set ascii foreground.
setab=\\E[4%p1%dm # set ascii background.
clear=\\E[H\\E[25 # clear the screen.
Those %-codes are like printf codes. They work like a stack. %p1 means push the
first argument on the stack. %p2 means push the second, etc. %d means a decimal
argument. %c is char and %s is string. So to set the foreground to color 5, you
actually send a command like this:
$ echo -ne '^[[35m'
Remember that you can get a literal escape by typing CTRL-V <ESC>.
