How can I change a read-only file to read-write in Linux?

To change a read-only file to read-write, you can use the chmod command to change the file permissions. Here are the specific steps:

1. Open the terminal and navigate to the directory containing the read-only files using the cd command.
2. Run the following command to change file permissions:

chmod +w 文件名

“File name” refers to the name of the file you want to change permissions for.

This will grant the file write permission, allowing it to be read and written.

Please note that you need sufficient permissions to change the file’s permissions. If you are the owner of the file or have root user privileges, then you should be able to successfully change the permissions.
