ok.. re previous post about "fix"
it doesn't work.. lol
why would:
tail -500 /var/log/maillog | grep -v imapd |grep -v connection |grep -v processing| cut -d" " -f0,3,6,7,8,9,10| grcat conf.craig
work.. but
This one ends the tail output and passes it to grep .... etc
tail -f /var/log/maillog | grep -v imapd |grep -v connection |grep -v processing| cut -d" " -f0,3,6,7,8,9,10| grcat conf.craig
*not* work..
This one never ends the tail output, so it never releases control to the following commands. Grep is waiting for the end of the input before it gives the output.
but:
tail -f /var/log/maillog | grcat conf.log
work..
Probably grep is waiting for the end of the input so it can finish processing, while great does similar to tail. It just streams the input to output.
Maybe you need to use a temp file as output of the tail, then use a cron to run the grep chain and pass it thru great. Or do as some have suggested and use a perl script to do the processing.
so it's not a problem with grcat I don't think..
any ideas?
