Date: Wed, 19 Mar 2008 20:09:25 +0200

Здравствуйте.
Возможно, ещё кому когда было интересно; тут немного
понадобилось, ну и нагуглил незамеченное ранее в test(1) для
определения того факта, что stdout у скрипта перенаправлен:
jrm@HAL$ if [ -t 1 ]; then echo tty; else echo pipe; fi
tty
jrm@HAL$ if [ -t 1 ]; then echo tty; else echo pipe; fi|cat
pipe
