Command's list - SAMHACKERSWORLD

chmod - give especific permissions to an specific file 

cat - look at, modify, or combine a file. You can also copy files with this command by "reading" it to another file instead of to the screen.

cd - change from one directory to another

cp - Copy a file from one location to another

dd - copies exact locations to other locations. Can be an entire drive, a folder, etc. dd if= of=. uses an input file and an output file.

df - how much free disk space. 

du - show disk usage of files. Add "-h" to get human readable. Especially useful when you add "-d1" to limit the directory depth to 1. If you run "du -h -d1", it will tell you how much space each directory occupies, including their contents summed.

exit - exits the shell you are in.

grep - search within a file for a text string. Also useful for parsing command output. 'ls | grep something' is a quick way to list files that contain the string "something" (although "ls *something*" would do it, too, but grep can do a lot more)

ifconfig- get network interface configuration. Good for getting your own IP address.

kill - kill a process by PID

ls - lists all files in a directory .

mv - Move a file from one location to another. 

ping - see if an internet host is alive

pm - android package manager. LOTS of useful things in here, type pm by itself for the help screen

ps - list processes. Useful to see what is running

reboot - reboots your device

reboot recovery - reboots you into recovery 

reboot-bootloader -reboots the device in bootloader- fastboot

rm - remove a specified file

rmdir - remove a directory. rm can't do it unless you remove recursively with -R

su - Substitute User. We type this to switch to the rootuser. You need to type this command first to do a lot of the other commands.

sync - synchronizes any data on disk with data in memory. We type this before rebooting to ensure we've got all data written

tar - creates taped archives. Compresses files like winzip, 7zip, winrar and others tar

top - like task manager, it displays running processes. in Linux the q key quits. On Android I don't know how to make it quit other than closing the app.

uptime - displays how long it has been since you last rebooted the system. Interestingly enough the "Menu Key > System > About Phone > Status > Up time" on my phone does not match "uptime" typed in the terminal emulator.
