I am on Ubuntu 16.04 and I want to search files for let’s say “if” and I want to the output until “endif”. The file could look like this
if … SOME CODE endif
I can do this with
grep -A9 if my_file | grep -B9 endif.
This doesn’t works if the “if” clause is larger than 9 and if several “if” clauses are in the same file and if the first grep command contains several “if” clauses. The option
-m1 in the second grep doesn’t help. Nested “if” clauses can be ignored. Has somebody an idea, maybe not with grep?
Difference to How do I grep for multiple patterns on multiple lines?
The question asks for a solution with
grepwhich is answered already in the question:
grep -A9 if my_file | grep -B9 endif. The solution doesn’t work in my case but would work in the case of the other question.
The proposed grep solutions of the other question don’t work (with Ubuntu?):
grep: ein nicht geschütztes ^ oder $ wird mit -Pz nicht unterstützt.which is something like
grep: a not protected ^ or $ is not supported with -Pz. I use the following:
root:/tmp# cat file Some text begin Some text goes here. end Some more text root:/tmp# grep -Pzo "^begin\$(.|\n)*^end$" file grep: ein nicht geschütztes ^ oder $ wird mit -Pz nicht unterstützt
The proposed solutions search only for pattern which start at the beginning of the line if I interpret the proposed solution correctly. Even if I remove
^the command doesn't work.
