Strip color codes from Rails logs

stripcolor

#!/bin/sh
# Strip color codes from Rails logs
# Examples:
#    stripcolor test.log > test.log.nocolor           # Save a copy of the log without color
#    stripcolor test.log | gist                       # Gist the log
#    stripcolor test.log | pbcopy                     # Copy the log to the clipboard in OSX
#    stripcolor test.log | xclip -selection clipboard # Copy log to clipboard in Linux
cat "$@" | sed -r "s/\x1B\[([0-9]{1,3}((;[0-9]{1,3})*)?)?[m|K]//g"

Another useful use of this script is in a pipe:

rake rails:upgrade:check | stripcolor | less
