1. Basic dir scan
- gobuster dir -u http://10.10.10.40 -w /usr/share/wordlists/dirb/small.txt
2. To select only specific types of responses use “-s”
- gobuster dir -u http://10.10.10.40 -w /usr/share/wordlists/dirb/small.txt -s 403
3. Search for files with extention sh,pl within /cgi-bin/
- gobuster dir -u http://10.10.10.40/cgi-bin/ -w /usr/share/wordlists/dirb/small.txt -x sh,pl
4. Print verbose of what is going on
- gobuster dir -u http://10.10.10.40/cgi-bin/ -w /usr/share/wordlists/dirb/small.txt -v
5. Identify content length
- gobuster dir -u http://10.10.10.40/cgi-bin/ -w /usr/share/wordlists/dirb/small.txt -l
6. Writing results to a file
-
- gobuster dir -u http://10.10.10.40 -w /usr/share/wordlists/dirb/small.txt -o results.txt
