Question

I tried to get some aliases from a specific config file in a short bash script. The config looks like:

[other config]

[alias]
alias: command -o option
alias2: command -l 2
alias3: command -o option

[other config]

How would you get these aliases separated? I would prefer a output like this:

alias: command -o option
alias2: command -l 2
alias3: command -o option

I already did some bad stuff like getting line numbers and so on…
Any Ideas? Would be great!

You can do this using sed:

sed -n -e '/\[alias\]/,/\[.*\]/s/:/:/p'

This will print all lines between [alias] and the next line containing [ and ] that have a colon on them.
