Top Forums Shell Programming and Scripting Piping the "script" command through the logger command. Post 302852841 by Corona688 on Thursday 12th of September 2013 01:12:19 PM

This is a tricky one, because each chain of pipes creates more possibilities for buffering and stalling.

Since you're creating a file anyway, why not tail it, to feed it into logger instead of putting a pipe in the way?

Code:
: > $LOGFILE.log
( tail -f $LOGFILE.log | /bin/logger ) &

trap "kill $!" EXIT # Kill the logger subshell on exit

${SCRIPT} -a -f -q ${LOGFILE}.log


I'm not sure that feeding raw, binary keystrokes into logger is a terrific idea, though. A lot of what script saves, only looks nice when dumped to a shell.

Also, instead of echo "" > /dev/null as a do-nothing stub, you can use the easier and simpler :
