As part of system automation work, the other day we were talking about changing the postfix configurations. Mention was made of using sed, but I brought out "postconf -e", a tool that postfix provides to allow modifying the configuration. Particularly useful for more complicated entries which can span multiple lines and a simple sed script wouldn't do the right thing.
You run it as: "postconf -e name=value"
This will modify the configuration to change the setting "name" so that is assigned the value "value". Of course, proper quoting is necessary if you are using special characters.
I also frequently use "postconf" to have it tell me what the current configuration is (because sometimes looking at the file it isn't obvious) and "postconf -d" to tell me what the default configuration values are.
Definitely useful tools to have in the tool-box.comments powered by Disqus
