terminfo Notes  

DESCRIPTION

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>.
