This is the command cgrep 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
cgrep - like grep(1) over all indexed files
cgrep [-c] [-h] [-i] [-l] [-n] regexp [ file... ]
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
-c Suppress normal output; instead print a count of matching lines for each input
-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.
Cgrep uses the index stored in $CSEARCHINDEX or, if that variable is unset or empty,
