Хозяйке на заметку (спасибо raorn@ за снятие с ручника насчёт subshell): $ zsh $ echo test | read a; echo $a test $ bash $ echo test | read a; echo $a $ echo test | ( read a; echo $a ) test $ При этом что-нить вроде такого работает, как ожидается: | while read first second junk; do # something with $first (first IFS-delimited word) # ...and with $second too... # the rest of the line goes to $junk done -- именно потому, что тут-то всё выполняется в одном сабшелле ;) А, и ещё: $ echo test:best | ( IFS=: read a b; echo $a/$b ) test/best -- ---- WBR, Michael Shigorin <mike@altlinux.ru> ------ Linux.Kiev http://www.linux.kiev.ua/
