[SOLVED] How to create array in bash from some lines in config file
I have config file for small script and it looks like this:
local_directory="$HOME/etc"
excluded_directory="$HOME/etc1"
excluded_directory2="$HOME/etc2"
excluded_directory3="$HOME/etc3"I would like to place all "excluded_directoryXX" config options into array that can be parsed to program. This way i have to hardcode it and it is not practical at all.
Can somebody help me out?

@jasonwryan
Thank you, i was not aware of that builtin. At first i wanted to use this in combination with "grep --after-context=XX" and then i realized that i can use it this way:
mapfile -s XX -t configs </etc; echo "${configs[@]}"Thank you very much.

Glad you got what you needed. I wasn't sure what sort of output you were looking for, it helps if you include that to remove ambiguity and/or uncertainty.
Please remember to mark your thread as [Solved] by editing your first post and prepending it to the title.

I am completely failing to understand what " </etc" is supposed to achieve. Is it shorthand for " </etc/somefile" or ... ?
But whether the Constitution really be one thing, or another, this much is certain - that it has either authorized such a government as we have had, or has been powerless to prevent it. In either case, it is unfit to exist.

Yes, it is reading stdin and in this case, it is somefile.
