Can't split a text file based on separator

Question

I\'m running Ubuntu 18.04 LTS. I have a text file named \"group_keys\", which contains a number of public keys that I\'d like to split based on the delimiter

---         


        

Answer 1

Try

csplit -z -f person_ -b '%d_key' group_keys '/-----BEGIN PUBLIC KEY-----/' '{*}'

which would output four files person_0_key, person_1_key, person_2_key, person_3_key where

• -z suppresses the generation of empty files
• -f person_ sets the output filename prefix
• -b '%d_key' sets the output filename suffix
• '{*}' sets the repeat count (repeat as many times as possible)

Answer 2

This should work:

awk '/-----BEGIN PUBLIC KEY-----?/{n++}{print > "person_" n "_key" }' group_keys
