Use the X permission, from the man page: The execute/search bits if the file is a directory or any of the execute/search bits are set in the original (unmodified) mode. Operations with the perm symbol 'X' are only meaningful in conjunction with the op symbol '+', and are ignored in all other cases. Wonderware Intouch 10.1 Sp3. So do the following: chmod -R a-x [directory] chmod -R a+rwX [directory] This removes the execute bit from all files and directories followed by adding read and write privileges to everything, and execute privileges to only directories. (No regular files have the execute bit on anymore from the first step.).

A common reason for this sort of thing is to set directories to 755 but files to 644. In this case there's a slightly quicker way than nik's find example: chmod -R u+rwX,go+rX,go-w /path Meaning: • -R = recursively; • u+rwX = Users can read, write and execute; • go+rX = group and others can read and execute; • go-w = group and others can't write The important thing to note here is that uppercase X acts differently to lowercase x. In manual we can read: The execute/search bits if the file is a directory or any of the execute/search bits are set in the original (unmodified) mode. In other words, chmod u+X on a file won't set the execute bit; and g+X will only set it if it's already set for the user. Try this python script; it requires no spawning of processes and does only two syscalls per file.

Apart from an implementation in C, it will probably be the fastest way of doing it (I needed it to fix a filesystem of 15 million files which were all set to 777) #!/usr/bin/python3 import os for par, dirs, files in os.walk('.' ): for d in dirs: os.chmod(par + '/' + d, 0o755) for f in files: os.chmod(par + '/' + f, 0o644) In my case, a try/catch was required around the last chmod, since chmodding some special files failed.

Is there a way to set chmod 755 for /opt/lampp/htdocs and all of its content including subfolders and files? Also, in the future, if I create a new folder or file. I have a number of files in this directory and I need to. Linux / UNIX: Change File Permissions Recursively. : : Appcrash : Photoshop.exe. Find and chmod command. To find all files in.
