Hello fellow freebsd-hackers,
Long-time hacker, first-time poster.
I'd like to share a shell script that I wrote for FreeBSD system
administration.
The attached shell script works similar to sysctl(8), but rather than
querying or working on sysctl MIBs, it instead works on the /etc/rc.conf
(and /etc/rc.conf.local) files.
Syntax shown below (available by running the script without arguments):
Usage: sysconf [OPTIONS] name[=value] ...
OPTIONS:
-h --help Print this message to stderr and exit.
-d Print list of internal dependencies before exit.
-e Print query results as `var=value' (useful for producing
output to be fed back in). Ignored if -n is specified.
-n Show only variable values, not their names.
ENVIRONMENT:
SYSCONF_SHOW_DEPS Dump list of dependencies. Must be zero or one
(default: `0')
RC_DEFAULTS Location of `/etc/defaults/rc.conf' file.
Examples:
root@mymachine ~ $ sysconf hostname
hostname: mymachine.localdomain
root@mymachine ~ $ sysconf hostname=foomaster.deluxe.com
hostname: mymachine.localdomain -> foomaster.deluex.com
root@mymachine ~ $ sysconf -e hostname
hostname="foomaster.deluxe.com"
root@mymachine ~ $ sysconf -n hostname
foomaster.deluxe.com
The script has zero external dependencies. None. Period. It will use
grep(1) if installed, but it is not required.
Tested extensively on FreeBSD-4.8, FreeBSD-4.11, FreeBSD-8.0, and
FreeBSD-8.1.
