hmmm.. if 'tail -f filename' continuously outputs using stdout, how could
I stop it when the text I'm looking for appears? I want tail to terminate
when it receives the following information:
caller=##########, conn='', name='username'
..and put those strings in variables for another program to use.
Something along the lines of:
tail -f /var/log/mgetty/mg_ttyS1.log | perl -ne 'if (/^caller=/)
{ print; exit 0; }'
could get you the raw data; then you could postprocess this data
however you want.
(This is completely theoretical; i.e., I haven't tested it.)
