Sed to read the file and replace and insert the pattern
 
Hi ,

I want to read from the file and check for the pattern, if the line has some word like <string>: then string should be copied into buffer.

Afterwards, I want to insert the same <string> with some word in the next line of the file.

Could you please help me out to use sed command to perform the above mentioned operations?

Thanks,
Saurabh

I think you'd better use awk

Moin,

do you mean this?

Code:

jan@jack:~/tmp> echo 'some text without the pattern
> and then the text with <string>: occurence
> and then the last line' | \
> sed -r '/<string>:/{p;s/.*<(string)>:.*/new word and \1/;}'
some text without the pattern
and then the text with <string>: occurence
new word and string
and then the last line

Jan
