mkdir

mkdir command is used to create directories. The command is followed by the names of the directories to be created.

$ mkdir virani

This command creates the directories virani

$ mkdir stud1 stud2 stud3

This command will create three directories stud1,stud2,and stud3.

$ mkdir virani virani/sci virani/arts

This creates three directories virani,two sub directories sci and arts under virani.The order of specifying arguments is important; you obviously can’t create a sub directory before creation of its parent directory.

Sometimes the system refuses to create a directory:

$mkdir maths

mkdir : can’t make directory maths

This can happen due to these reasons:
• The directory maths may already exist.
• There may be an ordinary file by that name in the current directory.
• The user doesn’t have the permission to create a directory.
