Your Guide to Basic Linux Commands Day02

#linux #cli

mkdir

Following the previous day commands on working with directories , The next command will be about how you can create a directory or a folder for yourself in the terminal. i.e mkdir
eg: mkdir newdirectory

There is a switch available for this command that allows you to create multiple directories within another directory by using mkdir -p
eg:mkdir -p mydir2/mysubdir2

rmdir

This command allows you to delete a directory when it is empty.otherwise it will show that the directory cannot be deleted.
eg:rmdir newdirectory

This also has the same switch that allows you to delete the parent directories recursively.
eg:rmdir -p mydir2/mysubdir2

File Management Commands

These commands allow you to create, modify , delete files.All the files are case sensitive and therefore treated as different files.

file

The file command shows the datatype of a file.Linux does not use extensions to determine the type of a file.The file command uses a magic file(literally it's name) that contains patterns to recognise file types.file is located in /usr/share/file/magic.
eg:file file54.pdf , file /etc/passwd

touch

The touch command allows you to create an empty file.
eg: touch file86.txt
Like other commands , This command also has multiple switches available like:

touch -t = allows you to set the time on when the file was created. eg: touch -t 2412311159 demo.txt

rm

This command removes a file forever since it will not be sent to trash or recycle bin.
eg:rm file86.txt

The switches available for this commands are:

rm -i = using this switch prevents accidental deletion of a file by asking for confirmation before deleting the file.
rm -rf = This switch recursively deletes the file forcefully. It can even delete everything if not used in the proper environment. So be careful when you use it.
