How to get variable from text file into Bash variable
bash, kill, pid
Solution
You're almost there:
CurPID=$(<"$PIDFile")
In the example you gave, you don't even need the temp variable. Just do:
kill -9 $(<"$PIDFile")
Problem
Simple question, in BASH I'm trying to read in a .pid file to kill a process. How do I read that file into a variable. All the examples I have found are trying to read in many lines. I only want to read the one file that just contains the PID ``` #!/bin/sh PIDFile="/var/run/app_to_kill.pid" CurPID=(<$PIDFile) kill -9 $CurPID ```
