Make programs think their stdout is a tty / terminal.
$ mkdir -p build && cd build $ cmake .. $ make $ sudo make install $ sudo ldconfig
Just prefix your command with stdoutisatty:
$ stdoutisatty ls --color=auto | less
Use a two-character environment variable ISATTY to specify whether you want stdout and/or stderr to be treated as a tty:
ISATTY value |
which isatty |
|---|---|
yy |
stdout, stderr |
y. |
stdout |
.y |
stderr |
. indicates any characer other than (lower-cased) y. Only the first two characters are examined (currently).
