grep -Pzo "(?s)^(\s*)\N*main.*?{.*?^\1}" *.cExplain: -P activate perl-regexp for grep (a powerful extension of regular extensions) -z supress newline at the end of line, subtituting it for null character. That is, grep knows where end of line is, but see input as a big one line. -o print only matching. Because using -z, all file is like a big line, so if there is a match, all file would be printed, this way it don't. in regexp: (?s) activate PCRE_DOTALL, which means that '.' find any character or newline \N find anything except newline, even with PCRE_DOTALL activated .*? find '.' in nongreedy mode, that is, stops as soon as possible. ^ find start of line \1 backreference to first group (\s*) This is a try to find same indentation of method As you can imagine, this print the main method in a C (*.c) source file.
