LPI Linux Essentials Exam 010-160 - Topic 2.4 - Create, Copy, Move & Delete Files
Managing files is a fundamental skill when working with Linux systems. In this guide we will focus on the key commands touch, cp, mv, and rm.
Whereas Windows operating systems are case insensitive, Linux operating system are case sensitive. Files myfile.txt and MyFile.TXT are two different files.
Creating Files
The touch command can be used to create empty files..
To create a single empty file:
touch filename
With the touch command, if the file already exists, then the access and modification time of the file is updated to the current time.
Copying Files
The cp command is used to copy files to another location or you can create a backup copy of a file in the same location.
To copy a file to another location:
cp source_file destination_directory/
To create a backup copy of the file in the same location:
cp source_file source_file.bak
Moving & Renaming Files
The mv command is used to move files to a different location and can also be used for renaming files.
To rename a file:
mv old_filename new_filename
To move a file to a different location:
mv filename /new/location/
Deleting Files
The rm command is used to delete files. This command is critical for managing unwanted or unnecessary files.
To delete a single file:
rm filename
