Copy lines starting and ending with specific pattern from multiple files to a file


Hi,

A function by name abc is called in many files. I want to copy all the lines with the function call to an output file.
A simple grep on function name doesn't help me as the function call is spanning across multiple lines as follows:

abc(parameter1,
parameter2,
parameter3);

So I want to copy all the three lines (till semicolon) to the output file.

The problem is because there are more than 200 calls for the same function and I cannot do it manually

Thanks in advance.

Hi,

It is not clear from your post if the function(s) you are looking for always span 3 lines.

Maybe one of these will do what you want:
Code:
always 3 lines
grep "^.*(" -A2 infile > outfile

Varying lines
sed -n '/.*(/,/);/p' infile > outfile
Hope this helps.

So how about:
Code:
awk 'BEGIN{ORS=RS=";"}/abc\(/' file
