Man1 - i3-dump-log.1
NAME
i3-dump-log - dumps the i3 SHM log
SYNOPSIS
i3-dump-log [-s <socketpath>] [-f]
DESCRIPTION
Debug versions of i3 automatically use 1% of your RAM (but 25 MiB max) to store full debug log output. This is extremely helpful for bugreports and figuring out what is going on, without permanently logging to a file.
With i3-dump-log, you can dump the SHM log to stdout.
The -f flag works like tail -f, i.e. the process does not terminate after dumping the log, but prints new lines as they appear.
EXAMPLE
i3-dump-log | gzip -9 > /tmp/i3-log.gz
