Well said. Just to complete the picture:
- ncurses is a high level library (text windows, scrolling,
highlighing, cursor motion, etc.)
- It is built on top of a low-level library called terminfo.
Terminfo can lookup a terminal model (from the TERM environment
variable) in the terminfo database and extract its capabilities
and escape sequences.
- Man terminfo(4) will give a catalog of all possible terminal
capabilities (most terminals use only a small subset).
- Man tput(1) will tell you about a small utility that when given
a capability name (and the TERM environment variable is well defined),
will output the correct escape sequence. Example:
tput smso; echo hello; tput rmso
Should work with any terminal that has a standout mode.
Looks like it would fit the bill of the original poster (given his shell
examples). Of course, if he would use perl, than perl has CPAN modules that
wrap both TermInfo and Curses.
Cheers,
