.SH NAME
cgrep \- like grep(1) over all indexed files
.SH SYNOPSIS
.B cgrep
.RB [\|\-c\|]
.RB [\|\-h\|]
.RB [\|\-i\|]
.RB [\|\-l\|]
.RB [\|\-n\|]
.IR regexp
.RB [

.RB ]
.SH 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.
.SH OPTIONS
.TP
.B \-c
Suppress normal output; instead print a count of matching lines for each input file.
.TP
.B \-h
Suppress the prefixing of file names on output.
.TP
.B \-i
Ignore case distinctions in both the \fIregexp\fP and the input files.
.TP
.B \-l
Suppress normal output; instead print the name of each input file from which
output would normally have been printed.
.TP
.B \-n
Prefix each line of output with the 1-based line number within its input file.


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