Parameters

File: Specifies the list of files for which you want to set time properties.

Examples are as follows

Touch A.txt

If you want to create multiple empty files in a row, you can separate them with spaces, such as: Touch a.txt b.txt c.txt d.log

Similarly, you can create a file with an absolute path

Touch-c F.txt If F.txt does not exist, the file is not created and if present the update file time is the current time

2. Update F.txt with the same timestamp as A.txt

Touch-r a.txt F.txt

3. Set the timestamp of the file

Touch-t 201801142234.50 A.txt
