Did You Know? netcat is a unix utility which reads and writes data across network connections, using TCP or UDP protocol. It's designed to be a reliable back-end tool that can be used directly or easily driven by other programs and scripts. At the same time, it's a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities. Netcat, or "nc" as the actual program is named, should have been supplied long ago as another one of those cryptic but standard Unix tools.

Creating directory in the Linux environment is very simple task. Let's create directory named "dir1":

mkdir dir1

mkdir command can take more arguments. For example we can take two directories with only one command:

mkdir dir2 dir3

mkdir command can also create entire directory tree. By using -p option mkdir will also create parent directories if required:

mkdir -p dir4/dir4.1

By default mkdir creates directory with permissions set by umask. To force mkdir to create directory with different permissions the -m option can be used. For example to create directory with [[chmod | permissions]] 744 we can issue following command:

mkdir -m 744 dir5

mkdir - create directory and set permissions
