Your blog is nice. I think you should add your blog at BlogAdda and let more people discover your blog. It's a great place for Indian bloggers to be in and I am sure it would do wonders for your blog.

Comment on Search and replace Shell Script by Ron

Ron — Tue, 17 Jul 2007 03:14:00 +0000

If you wanted to modify the files in place, you could have used ed instead of sed and done something like this:

ed -s /target/file [[EOF
g/Bombay/s/Bombay/Mumbai/g
w
q
EOF

You will have to replace the [[ with less-than less than. I couldn’t find the correct syntax for this editor so it wouldn’t interpret them as html.

The downside is that instead of making a modified copy of the file, you’re editing the file directly.

I just published a scripting book and I talk about this technique in Chapter 25. It can be found at Amazon and other sites:

This looks good.

You might consider an option for checkpointing (in addition to stop/start) to invoke checkpointing using the same environment variables and the like.
