Learning basic Linux commands

The following table lists a few basic Linux commands:

Command	Description
`$ ls`	This command is used to check the contents of the directory.
`$ pwd`	This command is used to check the present working directory.
`$ mkdir work`	We will work in a separate directory called `work` in our `home` directory. Use this command to create a new directory called `work` in the current folder.
`$ cd work`	This command will change our working directory to the newly created directory `work`.
`$ pwd`	This command can be used to verify whether we moved to the expected directory.
`$ touch hello.sh`	This command is used to create a new empty file called `hello.sh` in the current folder.
`$ cp hello.sh bye.sh`	This command is used to copy one file into another file. This will copy `hello.sh` as `bye.sh`.
`$ mv bye.sh welcome.sh`	This command is used to rename a file. This will rename `bye.sh` as `welcome.sh`.
`$ ll`	This command will display detailed information about files.
`$ mv welcome.sh .welcome.sh` `$ ls`	Let's see some magic. Rename the file using the `mv` command and the run the `ls` command. Now, the `ls` command will not display our file `.welcome.sh`. That file gets hidden. Any filename or directory name starting with "`.`" (dot) becomes hidden.
`$ ls -a`	This command is used to see hidden files.
`$ rm .welcolme.sh`	This command is used to delete the file.

Note

If we delete any file from GUI such as Graphical User Interface, then it will be moved to the /home/user/.local/share/Trash/files/ all deleted files folder.
