sed optimized for replace substring
Hi All,
I have this text file

Code:
 IR7013903069171012INT10171211864
 Axxxxxxxxxx12345dddddddddddd
 Byyyyyyyyy99999999ddddddddd
 IR7013903069171012TOS10171211865
 Cffffffffff5745747ehdefffffffffgggggggg
 Dyyyyyyyyy99999999ddddddddd

I need to
1) find lines where the substring IR70139 is present
2) only in the lines selected by the point 1, I need to replace the substring INT and TOS by SFD

I have used this command

Code:
cat <input filename>| grep IR70139 | sed s/INT/SFD/  > output_file

Is there a better command line to execute my command?

For example
Code:
sed /search string1/,/search string2/ {  s/INT/SFD/  s/TOS/SFD/ } < inputfile > outputfile

I have tried but without success.

Any help will be well appreciated.

Thanks in advance for your kind support.

Regards,

Giovanni

Try:
Code:
sed '/IR70139/{s/INT/SFD/g; s/TOS/SFD/g;}' infile

Try like...

Code:
awk '/^IR70139/' test.txt|sed 's/INT/SFD/g;s/TOS/SFD/g'

Why awk when a single command with sed would have taken care of the same condition you have used in awkSmilie...like scrutinizer has put across
