teelim

README

teelim

Reads from stdin, and writes directly to given output path. Will ensure that file size never exceeds given max. Uses the fallocate syscall to truncate file from the start, requires a filesystem that supports FALLOC_FL_COLLAPSE_RANGE.

An example use is as an alternative to logrotate. By passing your service output through teelim you can guarantee a file size that never exceeds given max, but always keeps the latest "max" number of bytes.

e.g. ./gotosocial --config-path ./config.yaml server start | teelim -d 10MiB -m 90MiB -p 0600 log.txt
