mkdir -- make a new directory
- New directory or subdirectory to be made.
Mkdir creates a new directory with the given name. Newdir may be an IRAF virtual directory name (not a logical name) or a host directory name.
1. Make a subdirectory named "sub1".
cl> mkdir sub1
2. Make a subdirectory "sub2" below "sub1". The subdirectory "sub1" must already exist.
cl> mkdir sub1/sub2
3. Make a directory "blue" at the same level in the directory hierarchy as the current directory (".." is a synonym for the previous directory).
cl> mkdir ../blue
