Attrib examples

attrib

Typing attrib by itself displays all files in the current directory and each of their attributes. If any file is hidden, it also displays those files.

As can be seen in the above example, we typed the dir command to list the files in the current directory and could only see the "computer.bat" file listed. However, if you type attrib by itself, there are three files in this directory, "computer.bat" with read-only, "example.txt" with hidden, and "hope.txt" with the hidden and read-only attribute.

attrib +r autoexec.bat

Add the read-only attribute to the autoexec.bat file to prevent it from being modified until the read-only attribute is taken off. This command is helpful for important system files or any other file that you do not want to have mistakenly edited or changed by another program.

attrib +h config.sys

Add the hidden attribute to the config.sys file, causing it to be not be seen by the average user.

attrib -h config.sys

This command does the opposite of the example shown before this command. Instead of hiding the file this command makes the file visible if hidden.

attrib +r +h autoexec.bat

Finally, this example adds two attributes to the autoexec.bat and makes the file read-only as well as hidden.
