How to find text in a file in bash and echo the output and add it to a variable
I'm trying to make a bash script that needs to find http://0.0.0.0:3468/*in a bunch of logs in /opt/plex/*.log, display it at the terminal for the user and at same time add it to a variable.
How can I do this?
Example : Print http://0.0.0.0:3468/abc to the terminal, and create a variable in the script called TOKEN=abc.
bash shell awk

Can you give some actual examples to come after/*and exactly say what you want to add it to a variable? By showing an example?

@Inian everything after /* is alphanumeric characters, I want to find that in the logs, print it to the user, and create variable TOKEN=/*

Based on supposed requirements from the comments, you need something like below
#!/usr/bin/env bash
token=()
while IFS= read -r line; do
printf '%sn' "$line"
token+=( "${line##*/}" )
done< <(awk '$0 ~ "http://0.0.0.0:3468/"' /opt/plex/*.log)
This will print all the matching lines containing the URL to the console. Instead of using a variable to store the token output you can use an array in bash to append the contents after / by using parameter expansion syntax of type ${word##*} which removes the string up to the last occurrence of / and prints the remaining string. So once your script is completed, you can print the token list as just
printf '%sn' "${token[@]}"
and access the individual token by looping over the array
for ((i=0; i< ${#token[@]}; i++ )); do
printf '%sn' "${token[i]}"
done
(or) as just using array indices ${token[0]}, ${token[1]} etc.
If your requirement just boils down to get a single string value from the multiple set of files, just use grep or Awk as
token=$(awk -vFS=/ '$0 ~ "http://0.0.0.0:3468/"{print $NF}' /opt/plex_autoscan/*.log)
(or) with GNU grep as
token=$(grep -oP 'http://0.0.0.0:3468/K.*) /opt/plex_autoscan/*.log
