dirb: command not found

The “dirb” command in Linux is a command-line tool used for web application directory enumeration. It is commonly used to discover hidden files and directories on a web server by brute forcing the directory names. The tool works by sending HTTP requests to a web server with a list of directory names and analyzing the responses to determine if the directories exist.

The basic syntax of the command is:

# dirb [options] [URL] [wordlist]

where:

URL is the target web server
wordlist is a file containing a list of directory names to try
options are various switches to customize the behavior of the tool

For example, “dirb http://example.com /usr/share/dirb/wordlists/common.txt” will perform directory enumeration on the target “example.com” using the common.txt wordlist.
