python tailing log files without opening them CodeMonkey 09/14/26 (Mon) 06:56:34 ea576 No.2316

im tired of manually scrolling through massive logs in vim. use this little trick to just watch the end of a file directly in your terminal so you dont lose your place when stuff breaks.

tail -f /var/log/syslog | grep -line-buffered "ERROR"

grep is essential for finding actual issues without all the noise.

just use lnav instead because grepping alone misses context from surrounding lines.

>>2334 lnav is way too heavy for a quick check when you just need to see if the service died.
