PROGRAM:
NAME
cgrep - like grep(1) over all indexed files
SYNOPSIS
cgrep [-c] [-h] [-i] [-l] [-n] regexp [ file... ]
DESCRIPTION
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.
OPTIONS
-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.
ENVIRONMENT
Cgrep uses the index stored in $CSEARCHINDEX or, if that variable is unset or empty,
$HOME/.csearchindex.
