Will this command work? chmod -R 644 *.php

I am trying to change all php files to 644 in the directory I am in now and all directories under it.

Hello abefrorman!

Yes, this command will work, but will change only all ".php" files in that directory recursively. To chmod all files and all subdirectory of an directory you have to do "chmod -R 664 firstdirectory" and it'll change everything in it.

Hope this helped, Boby!

If the goal is to change only files that end with ".php" in the current directory and all subdirectories, then you'll need something else.

As Boby mentioned, the original command "chmod -R 644 *.php" will only chmod files in the current directory that end with ".php"

Boby's command will recursively chmod any file beneath the specified directory (no matter what extension the file has).

The find command is probably the right tool for the job:
That will find every regular file that ends with ".php" in the /top/level/directory and all subdirectories and it will execute "chmod 644 <found filename>" for each one.

is more efficient, though, as it doesn't result in spawning a new chmod(1) process for each file found.
