Thanks!!!

牛逼！

thanks

Thanks

love your work

based man

More flexible, take the container ID as the first argument, and pass remaining arguments to grep

#!/usr/bin/env bash
#
# Docker outputs logs to stderr not stdout, redirect output for the specified container and
# pass remaining arguments to grep
# 
# Usage:
#   dockergrep.bash [container ID] -i error
#   dockergrep.bash [container name] 127.
#   dockergrep.bash [container name] -C 3 Successfully
#   
docker logs "$1" 2>&1 | grep "${@:2}"

thks

you are powerful

excellent！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！ You are the one who knows "2>&1" well.

if you get "grep: (standard input): binary file matches" error, when doing e.g. --since=48h, try this:

docker logs nginx 2>&1 | grep -a "127."
