строкастрока

and changed

 [script] строка[script] строка
  • Not quite clear. Does he write logs by himself? Or use syslog? - Anton Shevtsov
  • He writes a log by himself. It looks like this: ./script.sh >> log - stanislav
  • echo 'line' | awk '{print "[script]" $ 0}'> /tmp/out.txt? - Anton Shevtsov

Can do so

 ./script.sh | while read line; do echo "[script] $line"; done >> log

The prefix in the loop is added to each line.
