-I am working in a bash script.
-The file size is always variable, so I couldn't use head or tail.

CONFIGURATION VARIABLES
The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced in that order to set configuration variables. Command line
options can be used to override configuration file settings. Environment variable settings are ignored for this purpose. The currently
recognised variable is:
