Once upon a time, before I knew better, I copied defaults/rc.conf to
rc.conf and edited it to my needs.
Therefore I had many lines in rc.conf which were unnessecary, because
they just repeated the defaults.
I have thrown together this script, which just outputs the needed lines
in rc.conf.
If VERBOSE is set, it also prints
##= Is default: Somelabel="somevalue"
if rc.conf and defaults/rc.conf agree on the value of Somelabel
##- Default: Somelabel="defaultvalue"
if rc.conf and defaults/rc.conf disagree on the value of Somelabel.
Btw, why can't I run this as a bang-script?
Typing ./defcheck just produces:
awk: cmd. line 1: ./defcheck
awk: cmd. line 1: ^ syntax error
- - - - filename: defcheck
#!/usr/bin/awk

# Quick hack to check if rc.conf unnessecary duplicate
# lines in defaults/rc.conf
#
# Assume all lines are in format label="value"
#
# Prints lines in rc.conf which are not in defaults/rc.conf
# If VERBOSE==1 below, also prints defaults.
#
# usage:
# cd /etc; awk -f defcheck
#
# Other files in defaults may be checked:
# cd /etc; awk -f defcheck -v CHECK=otherfile.conf
