I have a bash command that outputs text in the following format:
Header 1
- Point 1
- Point 2
Header 2
- Point 1
- Point 2
Header 3
-Point 1
- Point 2
...
I want to parse this text into an array, separating on the empty line so that array[0] for example contains:
Header 1
- Point 1
- Point 2
And then I want to edit some of the data in the array if it satisfies certain conditions.
I was looking at something like this Separate by blank lines in bash but I'm completely new to bash so I don't understand how to save the output from awk RS=null to an array instead of printing it out. Could someone please point me in the right direction?
You can use readarray command to populate a bash array after reading your file with gnu awk command with empty RS that lets awk split records on empty lines and using ORS as \0 (NUL) byte:
IFS= readarray -d '' arr < <(awk -v RS= -v ORS='\0' '1' file)
Check output:
echo "${arr[0]}"
Header 1
- Point 1
- Point 2
echo "${arr[1]}"
Header 2
- Point 1
- Point 2
echo "${arr[2]}"
Header 3
-Point 1
- Point 2
