Can you extract (remove) lines from log files?
I use "MineOS" (a linux distro with python scripts and web ui included for managing a Minecraft Server). The author of the scripts is currently having a problem with the Minecraft server log file being spammed with certain entries. He's working on clearing up the spam.
But in the meantime, I'm wondering if I can run a shell script that will occasionally remove these spam lines (and only these lines) to keep the log file more manageable. Here is an example of the spam:
2013-08-02 20:51:30 [SEVERE] Reached end of stream for /127.0.0.1
2013-08-02 20:51:30 [INFO] /127.0.0.1:52343 lost connection
2013-08-02 20:51:30 [SEVERE] Reached end of stream for /127.0.0.1
2013-08-02 20:51:30 [INFO] /127.0.0.1:52344 lost connection
The consistent piece is the "
[SEVERE] Reached end of stream for /127.0.0.1". I would like to remove that entire line PLUS the single line that immediately follows each time (that lists 127.0.0.1:##### lost connection). But I don't want to remove other entries from the log file (named, "server.log" btw).
Is there a way to parse this server.log and selectively delete lines?
