Question
I am working on a Ubuntu 12.04 and writing a environment-auto-build shell. In the shell I need to change something in rc.local.
This is my rc.local now.
#!/bin/sh -e
#......
exit 0
I want to modify it like this:
#!/bin/sh -e
#......
nohup sh /bocommjava/socket.sh &
exit 0
Now I use nano to modify it, is there any command that can insert the line into rc.local?

The easiest would be to use a scripted language (ex: python, perl, etc...).
#!/usr/bin/env python
import os
with open('/etc/rc.local') as fin:
with open('/etc/rc.local.TMP') as fout:
while line in fin:
if line == 'exit 0':
fout.write('nohup sh /bocommjava/socket.sh &\n')
fout.write(line)
# save original version (just in case)
os.rename('/etc/rc.local', '/etc/rc.local.jic')
os.rename('/etc/rc.loca.TMP', '/etc/rc.local')
