How to find and change a specific text in a text file by using shell script


Hi All,
I am using shell script programming and I have text file consistes of 2 fields separated with TAB space, I want to search for a specific value in the second feild then change that value and then read the value of the first field of the same record.

the text file is

0 198.12.45.30
1 250.12.180.129
2 110.115.20.128
3 200.200.2.200

for example I want to find the value 110.115.20.128, change it to 0.0.0.0 and read the value of the first field for the same record which is 2.

so could u tell me how can I do this operation by using shell script programming?

Regards
Bassam

well

I'd recommend
awk
sed
grep
for loops
What I recommend is you go to www.tldp.org and read their advanced bash scripting guide. It will have all the info you are looking for when combined with man pages.
