tailer

tails multiple files and outputs with prefixes wheater they exist or not.

why: tail -f / tail -F multi file output is horrible and it doesn't handle all cases when files come and go

example

$ tailer test1 test2
  test1: hello
  test2: world
  test1: again

custom prefixes

$ tailer test1:t1 test2:t2
  t1: hello
  t2: world
  t1: agin

install

COPY --from=ghcr.io/matti/tailer /tailer /usr/local/bin
