14. **cp** - copy files and directories
- Use 'cp' to copy a file or a direcotry with files inside it to another location using command 'cp CURRENT_FILE-LOCATION DESTINATION_FOLDER'. Add '-r' flag to copy a directory that is not empty.

15. **du** - estimate file space usage
- Use 'du' to estimate file space usage. du is abbreviation of "disk usage". This command tool reports usage by given directory
15. **ln** - link LINKNAME to TARGET file/directory
16. **ln** - link LINKNAME to TARGET file/directory
- Link is pointer which connects file name to actual bytes of data on the disk. More than one link can point on the same data.
- Use `ln` to create a link to targeted file with linkname. Link to target is created in current working directory. By default ln creates [hard link](http://www.linfo.org/hard_link.html) and requires existance of TARGET file/directory. If we add `-s`(--symbolic) to the command, [symbolic link](https://www.computerhope.com/jargon/s/symblink.htm) will be created.
16. **top** - shows the system load
17. **top** - shows the system load
- Use `top` to get information about running processes of your system, the amount or RAM they allocate and the CPU percentage that they use. 'Top' is interactive so do not forget to press `q` when you want to quit.
17. **df -h** Checks disk space in human readable form
18. **df -h** Checks disk space in human readable form

21. **kill** - stops runing process
- The `kill` command sends a signal to a running process. This default action normally stops processes. If you want to stop a process, specify the process ID (PID) in the `ProcessID` variable. The shell reports the PID of each process that is running in the background (unless you start more than one process in a pipeline, in which case the shell reports the number of the last process). You can also use the `ps` command to find the process ID number of commands.
21. **find** - search for files in a directory hierarchy
22. **find** - search for files in a directory hierarchy
- `find` searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence, until the outcome is known (the left hand side is false for and operations, true for or), at which point `find` moves on to the next file name.
22. **man** - Show the manual for a command
