Apply write protection

You can write-protect specific files, directories, and volumes to prevent unauthorized programs or users from changing them.

Task

Run this command at the command prompt.

sadmin write-protect [ -i ] pathname1 ... pathnameN

Paths can include wildcard characters. When using wildcards, make sure that the specified string matches a limited set of file paths or file names. If the specified string matches many files, we recommend you revise the string.

Paths can include the * wildcard character. Using/abc/*/def is allowed while /abc/*.sh, /abc/*.*, or /abc/doc.* is not supported.

For example:

# sadmin write-protect –i /etc/security/limits.conf

You can also write-protect network file systems by specifying the network path with the sadmin write-protect command to prevent any change to the network share.

This table describes how you can specify the network path with the command.
Syntax	Example
`sadmin write-protect -i /mount-point`	Specify the mount point name on the Linux platform. For example: `sadmin write-protect –i /nfs`
