Porady Admina: egrep

W dzisiejszym wpisie z cyklu Porady Admina przybliżę program egrep https://linuxiarze.pl/porady-admina-egrep/

[froxictog]

I don't either, but we can solve this with shell scripting!

The terminfo database is queryable² using toe and infocmp:

toe -a | cut -f1 \ | while read tty; do infocmp -0 $tty | egrep -v '^#' done \ | fgrep -v 'colors#' \ | sed -n -E ' /,cols#.*,lines#/ { s/^([^,]+).*,cols#([0-9]+).*,lines#([0-9]+).*/\2 \3 \1/ p }' \ | sort -gr | uniq

This will list all terminals your local terminfo DB knows about, excluding colour terminals¹, sorted by number of columns descending, then number of lines descending within that, and display width, height, and terminal name for each one.

There's a lot of entries for "wide modes" of terminals that otherwise have a more conventional 80x24 ~4:3 display, like vt100-w (DEC VT100 wide mode, 132x24, about 6.6:3), but my pick would be vt50, a 70s DEC terminal with a native display of 80x12.

¹ I'm assuming your display is monochrome. If not, you might still want to start out mimicking a monochrome terminal just for simplicity.

² toe | cut gets you all the terminal names it knows about; infocmp | egrep displays the contents of the database for each terminal; fgrep filters out ones with colour support; sed extracts just the size and name information; and finally sort | uniq deduplicates and orders the result descending numerically.

Hey Foone, I'm building my own terminal from scratch (don't worry, no 7400-series logic, just an FPGA and my very limited VHDL skills).

I have absolutely no idea about the control sequences the computer sends, and how to handle them. You seem like you could've done something like this for fun.

Do you have any pointers to resources or something?

Yeah, Termcap/terminfo and ANSI escapes are what you’re looking for. ANSI escapes is the standard for talking to terminals, Termcap is the database of terminals (and the library to access it) that explains how each terminal works.

So what you’d want to do is find a terminal in Termcap and make your terminal work just like that one, so Linux (and other unixes) know how to talk to it.
