File management in Unix environment
Directory management
In Unix environment, you can create a directory with the mkdir <new_dir>
command.
For instance, you can create the directory images
at the root of your system using the command:
mkdir /images
You can also create a full list of directories and subdirectories using in 1 comamand using the -p
parameter.
mkdir -p /images/sub1/sub2
will create the complete directory hierarchy structure in one single line.
The
mkdir
command manual is accesible here: mkdir
File management
You can change a file timestamp using the touch <file>
command.
touch /hello.txt
will update the access and modification time of the hello.txt
file. If the file does not already exists on the system, it will be created with an empty content.
In practice
Create an empty file called valid_file under the directory /foo/bar/valid_file
