Module: kamailio Branch: master Commit: 59d287586f502a8df71c2e91899fde49594e072e URL: https://github.com/kamailio/kamailio/commit/59d287586f502a8df71c2e91899fde4… Author: Sebastian Kemper <sebastian_ml(a)gmx.net> Committer: Sebastian Kemper <sebastian_ml(a)gmx.net> Date: 2018-10-07T19:03:51+02:00 kamctl: make jsonrpc filter portable The filter has a regex looking for a literal '{' in the beginning of a line. Some awk implementations interpret this as a meta character, so the regex is deemed broken. Example with busybox awk (POSIX): root@hank2:~# kamctl ps awk: bad regex '^{.+"id"[ ]*:[ ]*[0-9]+[ ]*}$': Invalid contents of {} root@hank2:~# To fix this enclose the character in square brackets. This always matches for a literal '{' and is portable.
