switchconf is a simple utility to comment/uncomment regions of files. Specifically it was created to change configuration files according to my location.
For example, say you have an internal yum repository in your job and you want to use that when you're in the office, but not when at home. You have the .repo file like this at home:
[fedora]
name=Fedora $releasever - $basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink...
enabled=1
gpgcheck=1
...
And when you are at work you change it to
[fedora]
name=Fedora $releasever - $basearch
baseurl=http://linux-ftp.mycompany.com/pub/mirrors/fedora/...
enabled=1
gpgcheck=1
...
Instead of changing it everytime, you can instead create this:
[fedora]
name=Fedora $releasever - $basearch
#:switchconf: work
baseurl=http://linux-ftp.mycompany.com/pub/mirrors/fedora/...
#:switchconf: home
mirrorlist=https://mirrors.fedoraproject.org/metalink...
#:switchconf:
enabled=1
gpgcheck=1
...
Then you run add these lines to /etc/switchconf (or ~/.switchconf):
/etc/yum.repos.d/fedora.repo:
comment: #
Running switchconf home will result in the file changing to
[fedora]
name=Fedora $releasever - $basearch
#:switchconf: work
#:off:baseurl=http://linux-ftp.mycompany.com/pub/mirrors/fedora/...
#:switchconf: home
mirrorlist=https://mirrors.fedoraproject.org/metalink...
#:switchconf:
enabled=1
gpgcheck=1
...
Similarly, running switchconf work will result in
[fedora]
name=Fedora $releasever - $basearch
#:switchconf: work
baseurl=http://linux-ftp.mycompany.com/pub/mirrors/fedora/...
#:switchconf: home
#:off:mirrorlist=https://mirrors.fedoraproject.org/metalink...
#:switchconf:
enabled=1
gpgcheck=1
...
