Add 5 lines of code to all the scripts in a directory
Hi Guys,
I need some tips on writing a Korn shell script that would look for certain lines of code and replace all the scripts in the directory with a few other lines. I have about 120 scripts that I need to modify.

Any suggestions would be appreciated!

Thanks,
Cool_avi

I dont have knowledge in Korn Shell Scripts.

But i believe you would find sed fit for it. After testing use the -i switch of it to make the changes in that file.

Are you are doing one-line-for-one-line replacements? That is, are you replacing something like
cd $HOME/old
with
cd $HOME/new
?

Hi Ken,
No, I want to replace 1 line with about 5 lines of code. Those 5 lines of code include an if loop.

Please let me know if you need any other information.

Thanks,

If you want to use sed, something like this will work.

It looks for the first line containing the word 'special' and replaces the whole line with a five-line 'if' statement.

Of course, I'm using GNU sed, which recognizes the -i switch. Not all versions of sed do. And I'm not sure all seds recognize the \n sequence.
Code:
#!/bin/sh
cd script-directory
for f in *; do
    test ! -x "$f"  &&  continue
    sed -i '/special/ s/^.*$/if \[ "$a" = 1 \]; then\necho "1"\necho "2"\necho "3"\nfi/;q' "$f"
done

Thanks Ken!

I haven't tried the solution yet. I would like to look into sed's syntax and interpret what you did.

I will let you know if I have any questions.

Thanks,
Coolavi
