The Linux Touch command is used to create an empty file or update the timestamp of an existing file. It is a basic but powerful command that can be very useful in various situations. In this tutorial, we will explore some quick and easy techniques to master the Linux Touch command.
Creating a New File
To create a new file using the Linux Touch command, simply specify the name of the file as a parameter. If the file does not exist, the Touch command will create it.
This command will create a new file named "myfile.txt" in the current directory. If the file already exists, the Touch command will update its timestamp without changing its contents.
By default, the Linux Touch command updates the access and modification timestamps of a file. However, you can also use the -c option to only update the timestamps of files that already exist.
touch -c myfile.txt
This command will update the timestamps of the "myfile.txt" file if it exists. If the file does not exist, nothing will happen.
Specifying Custom Timestamps
In addition to updating the timestamps of files, the Linux Touch command also allows you to specify custom timestamps using the -t option.
touch -t 202112311200 myfile.txt
This command will set the access and modification timestamps of the "myfile.txt" file to December 31, 2021, at 12:00 PM. You can specify the timestamp in the format "YYYYMMDDHHMM", where: - YYYY represents the year. - MM represents the month. - DD represents the day. - HH represents the hour. - MM represents the minute.
Creating Multiple Files
The Linux Touch command also allows you to create multiple files at once by specifying their names as parameters.
touch file1.txt file2.txt file3.txt
This command will create three new files named "file1.txt", "file2.txt", and "file3.txt" in the current directory.
In this tutorial, we have explored some quick and easy techniques to master the Linux Touch command. We have learned how to create new files, update timestamps, specify custom timestamps, and create multiple files at once. The Touch command is a powerful tool that can be used in various scenarios, making it a valuable addition to your Linux command-line arsenal.
