renmae xmlrpc.php from all /home/*/public_html directory

You can use the find command along with the exec action to search for all xmlrpc.php files under /home/*/public_html/ and rename them to xmlrpc.php-back. Here is the modified command:

sh
find /home/*/public_html/ -type f -name "xmlrpc.php" -exec mv -v {} {}-back \;

Explanation:

1. find: This command is used to search for files and directories based on a given expression.

2. /home/*/public_html/: This searches within the public_html directories of all users.

3. -type f: This option ensures that find only looks for files.

4. -name "xmlrpc.php": This finds all files named xmlrpc.php.

5. -exec: This option allows you to pass another command that will be executed on every file found.

6. mv -v {} {}-back: This is the mv (move) command used to rename files. The {} symbol is a placeholder that find replaces with the current file path. So mv -v {} {}-back effectively renames each found file by appending -back to its name. The -v option makes the mv command verbose, so it will print what it's doing.

7. \;: This ends the -exec command. It is escaped with a backslash to prevent the shell from interpreting it as the end of the whole find command.

Note: Ensure you have the proper permissions to rename files in those directories, otherwise, you may encounter an error. Also, be careful while using this command as it will rename all matching files permanently.
