awk or sed to edit config files?

[bluetrepidation]

Hi all,

I have a bunch of files I need to change.
Before:
sip line1 auth name:
sip line1 password: xxxxxxxx
sip line1 user name: 232

After:
sip line1 auth name: 232
sip line1 password: xxxxxxxx
sip line1 user name: 232

Each file is named with a MAC address beginning with 3 zeros. Basically I need to copy the "user name" to the end of the "auth name" line. I was messing with awk to search for fields with "user" in them then print column 5 to the screen:

awk '/user/ { print $5 }' 000*

How to I write this back to the same file at the end of the auth line? Pipe to sed?

Thanks,
A.J.

if you have Python and able to use it

#!/usr/bin/env python
import sys,glob
for file_to_change in glob.glob("000*"):
    data=open(file_to_change).readlines()
    data=[i.strip() for i in data]
    number=data[-1].split(": ")[-1]
    data[0]=data[0]+number
    open("temp","w").write('\n'.join(data)+"\n")
    os.rename("temp",file_to_change)

What can't you use Python for? I'll give this a try and let you know!

Thanks again,

If each file is indeed only three lines, you might as well stick to
the shell:

for file in 000*
do
  {
    read line1
    read line2
    read line3 name
  } < "$file"

  {
    printf "%s %s\n" "$line1" "$name"
    printf "%s\n" "$line2"
    printf "%s %s\n" "$line3" "$name"
  } > "$file"
done

if that's the case (only 3 lines),

import glob
for file_to_change in glob.glob("000*"):
    f=open(file_to_change)
    firstline = f.readline()
    secondline = f.readline()
    lastline,number = f.readline().split(":")
    f.close()
    o=open("file","w")
    o.write(firstline[:-1]+":"+number+"\n")
    o.write(secondline)
    o.write(':'.join([lastline,number]))
    o.close()
