What if linux can't save the file? I believe there are many people do not understand, today, in order to let you know more about linux, so give you a summary of the following content, let's look down together.

What if linux vi cannot save the file?

Linux system vi edits read-only documents can not be saved solutions, use ordinary users to edit nginx.conf and other configuration files:

When saving, you will be prompted: if there is no Root Permission, you can use the following methods: add:

W! sudo tee%

In view of the error that vi cannot save the file, and the current user sudo permission may not be configured, prompt "xxx is not in the sudoers file. This incident will be reported." when using sudo, where XXX is the user name, that is, the user name does not have permission to use sudo, just modify the / etc/sudoers file. Here is how to modify it:

1. Enter superuser mode. That is, enter "su -", the system will let you enter the superuser password, enter the password to enter the superuser mode.

two。 To add write permissions to the file, enter the command "chmod Ubunw / etc/sudoers".

3. Edit the / etc/sudoers file. That is, enter the command "vim / etc/sudoers", type "I" to enter edit mode, find this line: "root ALL= (ALL) ALL" add "xxx ALL= (ALL) ALL" (where xxx is your user name) below, and then save (that is, press the Esc key first, and then type ": wq") to exit.

4. Revoke write permissions for the file. That is, enter the command "chmod Umurw / etc/sudoers".

Save again:

# check whether the save is successful: $grep sudo nginx.conf#test: W! sudo tee%
