Might split up the fields with a Perl line such as: = split(' ', $host_line) Example 13.14, “A typical example of grepable output” shows six fields:Ī Protocols section is included in IP protocolĭepend on Nmap options used. Theįields are separated by tab characters (ASCII number nine, ' '). The host line is split into fields, each of which consist of aįield name followed by a colon and space, then the field content. Of the available ones would have its own Host line. The comment lines are self-explanatory, leaving the meat of grepable output Well as OS and version detection ( -A) were requested. The command-line here requested that grepable output be sent to # Nmap done at - 1 IP address (1 host up) scanned in 21.90 seconds # Nmap 5.35DC18 scan initiated as: nmap -T4 -A -v -oG. The times and dates haveīeen replaced with to reduce line length. Will not further change the grepable output. Increasing the verbosity level beyond one -v Particular comment is only printed in verbose ( -v) I shortened it to avoid wasting dozens of lines.

One of the comment lines enumerates the port numbers that were Started, the command line options used, and completion time and statistics. There are also three lines starting with a hash prompt (not counting Line, but I split this entry into seven lines to fit on the page. Piped to an awk or cut command to print the desired fields. Finding all the hosts with the SSH port open or thatĪre running Solaris takes only a simple grep to identify the hosts,

Even I usually use it for one-off tests done at theĬommand line. Searched and parsed with standard Unix tools such as grep, awk, cut,

Simple format that lists each host on one line and can be trivially Nevertheless, grepable output is still quite popular. XML is extensible to support new Nmap features as theyĪre released, while I often must omit those features from grepable Of excellent parsers are available, while grepable output is my own The XML output format is far more powerful, and is nearly asĬonvenient for experienced users. This output format is covered last because it is deprecated.
