cgrep - like grep(1) over all indexed files

       This manual page was written by Michael Stapelberg <stapelberg@debian.org>, for the Debian  project  (and
       may be used by others).

       Cgrep behaves like grep, searching for regexp, an RE2 (nearly PCRE) regular expression.

       The  -c, -h, -i, -l, and -n flags are as in grep, although note that as per Go's flag parsing convention,
       they cannot be combined: the option pair -i -n cannot be abbreviated to -in.

       Cgrep uses the index stored in $CSEARCHINDEX or, if that variable is unset or empty, $HOME/.csearchindex.

-c     Suppress normal output; instead print a count of matching lines for each input file.

       -h     Suppress the prefixing of file names on output.

       -i     Ignore case distinctions in both the regexp and the input files.

       -l     Suppress normal output; instead print the name of each input file from which output would normally
              have been printed.

       -n     Prefix each line of output with the 1-based line number within its input file.

cindex(1), csearch(1), grep(1).
