Update cfg files

[Darrell]

This gives a diff for you to see then asks if you want to replace the old cfg file. In all cases the new cfg files and backups of your old ones are copied to a backup directory.
Your old ones are backedup only if you decide to change them.

Save this to a cfgUpdate.py file and type "python cfgUpdate.py"

import glob, os, sys, re


pf= os.popen("find /etc -iname '._cfg????_*'")
backDir="/etc/cfgBack/"
os.system("mkdir %s"%backDir)
for l in pf.readlines():
if l.find(backDir) != -1:
continue
l=l.strip()
base=l.split("_")[-1]
newCfg=re.findall("/(._cfg.*)", l)[0]
basePath=re.findall("(.*)/._cfg", l)[0]
cmd="diff -b %s %s/%s"%(l,basePath,base)
backUpCmd="cp %s/%s %s/%s.back"%(basePath,base, basePath, base)
acceptCmd="cp %s %s/%s"%(l, basePath, base)
print '*********************',cmd
res= os.system(cmd)
backUpNewCfg="cp %s %s%s"%(l,backDir, newCfg)
print backUpNewCfg
assert(os.system(backUpNewCfg)==0)
if res==0:
print "Skip"
else:
yn=raw_input("Accept all changes: y/n")
if yn in "Yy":
print 'Backup:', backUpCmd
print 'Do:', acceptCmd
assert(os.system(backUpCmd)==0)
assert(os.system(acceptCmd)==0)
assert(os.system("rm %s"%l)==0)

If you're looking for a polished interface that does the same thing, try emerging gentoolkit and running 'etc-update'.

I get an error:

File "cfgUpdate.py", line 8
if l.lfind(backDir) != -1:
^
IndentationError: expectd an indented block

[alec]

You might need to reemerge it. I've also noticed that some tools like etc-update and ebuild need me to source /etc/profile before they work (when using su from console).

I did an etc-updat, and then it worked

Thanks
