Useful as a starting point for a Linux service script. The parameters in the header comments (service-name, chkconfig, etc.) are specific to Red Hat-like Linux distributions and would be ignored in a Debian environment. Make script executable and place in /etc/init.d, then run appropriate chkconfig or update-rc.d command to add as a service.
#!/bin/sh
#
# service-name Service Name and brief description
#
# chkconfig: 2345 96 06
# description: Service Name and brief description
# processname: service-name
###########################################################################
# Modify the below variables do determine how the service is run

Force default shell to Bash. This is especially useful when user does not exist in /etc/passwd. Place this snippet at the end of /etc/profile or ~/.profile.
case $- in
*i*)
# If $BASH is not defined then we're already in a Bash shell
if [ -z "$BASH" ]; then
BASH_BIN=$(command -v bash)
# Ensure Bash is installed on the system, then switch shells
if [ -x "$BASH_BIN" ]; then
export SHELL="$BASH_BIN"
exec "$BASH_BIN"
fi
