This is the command csearch that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
csearch - like grep(1) over all indexed files
SYNOPSIS
csearch [-c] [-f fileregexp] [-h] [-i] [-l] [-n] regexp
DESCRIPTION
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 expression
fileregexp.
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:
cindex path...
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.
OPTIONS
-c Suppress normal output; instead print a count of matching lines for each input
file.
-f fileregexp
Restricts the search to files whose names match the RE2 regular expression
fileregexp.
-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
Csearch uses the index stored in $CSEARCHINDEX or, if that variable is unset or empty,
$HOME/.csearchindex.
