How to get variable from text file into Bash variable

Question

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 man

Answer 1

You're almost there:

CurPID=$(<"$PIDFile")

In the example you gave, you don't even need the temp variable. Just do:

kill -9 $(<"$PIDFile")
