csearch - like grep(1) over all indexed files
[-c] [-f fileregexp
] [-h] [-i] [-l] [-n] regexp
Csearch behaves like grep over all indexed files, 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.
The -f flag restricts the search to files whose names match the RE2 regular
Csearch relies on the existence of an up-to-date index created ahead of time. To
build or rebuild the index that csearch uses, run:
where path... is a list of directories or individual files to be included in the
index. If no index exists, this command creates one. If an index already
exists, cindex overwrites it. See cindex
(1) for more details.
- Suppress normal output; instead print a count of matching
lines for each input file.

- Restricts the search to files whose names match the RE2
regular expression fileregexp.
- Suppress the prefixing of file names on output.
- Ignore case distinctions in both the regexp and the
- Suppress normal output; instead print the name of each
input file from which output would normally have been printed.
- Prefix each line of output with the 1-based line number
within its input file.
Csearch uses the index stored in $CSEARCHINDEX or, if that variable is unset or
