I am trying to capture the currently logged in user on the linux box into a variable and then use the variable to insert it into a text file and replace the username in that file
in the file (live.conf) i want to replace the line : "live_user=whatever" with "live_user=myvariable"
My script looks like this :
#!/usr/bin/env bash
username=${USER:=$(/usr/bin/id -run)}
sed -i -r 's/^#?(live_user)\s*=.*/\1=$username/' live.conf
exit 0
however the result is it replaces the line now to look like this :
"live_user=$username" and not the actual variable...
Anyone have any ideas on how i can make this script work ?
