This is wonderful perl script to check the web server security and vulnerability .Get it from here :http://www.cirt.net/nikto2 Here are some key features of "Nikto": ? Uses rfp's LibWhisker as a base for all network funtionality ? Main scan database in CSV format for easy updates ? Determines "OK" vs "NOT FOUND" responses for each server, if possible ? Determines CGI directories for each server, if possible ? Switch HTTP versions as needed so that the server understands requests properly ? SSL Support (Unix with OpenSSL or maybe Windows with ActiveState's Perl/NetSSL) ? Output to file in plain text, HTML or CSV ? Generic and "server type" specific checks ? Plugin support (standard PERL) ? Checks for outdated server software ? Proxy support (with authentication) ? Host authentication (Basic) ? Watches for "bogus" OK responses ? Attempts to perform educated guesses for Authentication realms ? Captures/prints any Cookies received ? Mutate mode to "go fishing" on web servers for odd items ? Builds Mutate checks based on robots.txt entries (if present) ? Scan multiple ports on a target to find web servers (can integrate nmap for speed, if available) ? Multiple IDS evasion techniques ? Users can add a custom scan database ? Supports automatic code/check updates (with web access) ? Multiple host/port scanning (scan list files) ? Username guessing plugin via the cgiwrap program and Apache ~user methods Show Sample Output

If your script needs to be run in a terminal, this line at the top will stop it running if you absent-mindedly double-click the icon, perhaps intending to edit it. (Of course this won't help with scripts that run in the background.)

Using the output of 'ps' to determine CPU usage is misleading, as the CPU column in 'ps' shows CPU usage per process over the entire lifetime of the process. In order to get *current* CPU usage (without scraping a top screen) you need to pull some numbers from /proc/stat. Here, we take two readings, once second apart, determine how much IDLE time was spent across all CPUs, divide by the number of CPUs, and then subtract from 100 to get non-idle time.

Super fast way to ftp/telnet/netcat/ssh/ping your loopback address for testing. The default route 0.0.0.0 is simply reduced to 0. Show Sample Output

This is useful for scripting. Show Sample Output

Using "wmic get * /value" within any Cygwin shell will return lots of Win/Dos newline junk ie "^M$" at the end of found value line, two lines ("$" Unix newline) above, and three below. This makes storing and or evaluating wmic queries as variables a pain. The method i suggest strips the mentioned junk, only returns the value after "OSArchitecture=", and includes only one Unix style newline. Other methods using sed|awk|cut can only handle the output of wmic cleanly when piped or using multiple sed statements. wmic OS get OSArchitecture /value | sed 's/\r//g;s/^M$//;/^$/d;s/.*=//' making wmic OS get OSArchitecture /value | grep -Eo '[^=]*$' a much cleaner and slightly less costly alternative.

Not better, but more lightweight (sed instead of perl). Above command is reduced due to length restriction of less than 256 characters and entity encoding of "Save" command on this page. This is complete command (best without entity encoding): echo -e '\x2Helo folks\t!\r' | sed "y/\x0\x1\x2\x3\x4\x5\x6\x7\x8\x9\xA\xB\xC\xD\xE\xF\x10\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F\x20/␀␁␂␃␄␅␆␇␈␉␊␋␌␍␎␏␐␑␒␓␔␕␖␗␘␙␚␛␜␝␞␟␠/" ␂Helo␠folks␉!␍ Show Sample Output

Easiest way to get the external IP address.

http://ifconfig.me is a web site which shows your public iP address. If you want use your own code, you can use PHP code such as: function getip() { return "".$_SERVER["REMOTE_ADDR"]; } echo getip(); ?> Then, you'll get your IP by 'curl yourfile.php'. Show Sample Output

usage = crontest "/path/to/bin" This version of this function will echo back the entire command so it can be copied/pasted to crontab. Should be able to be automagically appended to crontab with a bit more work. Tested on bash and zsh on linux,freebsd,aix Show Sample Output

Run a nohup script in background launched trough a shell script without interrupting the main shell script execution.

If you have many port mappings, docker ps output becomes pretty illegible. The ~120 char one-liner changes the output into a more readable list of container! Show Sample Output

Same as `>`, except that the file is truncated to zero length if it exists, even if CLOBBER is unset. This works whatever your shell is and whatever your OS is. The most upvoted answer does not work with ZSH by default. The truncate version does not work on MacOS (and probably others).

For example, if you have a locally hosted git server, plus github, plus gitlab.

With this command you can use shell variables inside sed scripts. This is useful if the script MUST remain in an external file, otherwise you can simply use an inline -e argument to sed.
