Shell Programming and Scripting

i have a huge script that i need to replace a bunch of lines in.

in that script, i have a chunk similar to:

Code:

JABABA=$(if [ afaf = fafaf ]; then

echo afafafa

afafafafaf

afafafafe

fdfdfdfadfadl

fafafafkkkk

fi)

I would like to replace the above chunk with:

Code:

JABABA=$(if [ afaf = sweef ]; then

echo blah blach

echo blah

echo blah

echo blah

echo blah

fi)

i attempted to do this manually but there are just too many instances of the the chunk i want to replace.

any ideas?

It would be better so see the example you are working on. For me personally, this is just a bit abstract. By all means, sanitise it to remove anything sensitive, but it would be useful to know.

If you are simply looking for a vi command to replace strings in a specific range of rows in a file (i.e. your script) then if you place the cursor at the start line of the range and press CNTL-G, you will get the line number displayed, e.g. line 123. Do the same at the end and let's say that tells you it's line 456. You can then issue something like:-

Code:

:123,456 s/searchstring/replacestring/

This will replace between lines 123 to 456 inclusive the first occurence on each line. If you want every occurrence on each line, then it's:-

Code:

:123,456 s/searchstring/replacestring/g

I hope that this helps, but if I've missed the point, please explain more of what you want to acheive and show us the source.

Is the script beyond a re-design where you write this as a function and pass in the parameters to test/respond with?
