Extract file and folders with specified permissions

Question

I pack a folder with lot of sub-folders and files in Windows with 7zip, upload to VPS and then run the command:

tar -xvzf file.tar.gz

then all unpacked files and folders have permissions of 777. How do I get it so that folders will have permissions of 755 and files 644?

Answer 1

Run the following commands in the root of the directory to set the desired permissions for your directories and files:

find . -type d -exec chmod 755 {}\;
find . -type f -exec chmod 644 {}\;

Answer 2

If you're running tar(1) as a regular user, it will apply your umask by default. If you're running tar(1) as root, then you can give --no-same-permissions command line option to ask tar(1) to respect the umask.

So: either run this as a regular user:

umask 022
tar zxvf file.tar.gz

or run this as root:

umask 022
tar zxvf file.tar.gz --no-same-permissions

You might want to stick umask 022 into your ~/.bashrc, ~/.bash_profile, or ~/.profile. (See bash(1) manpage for full details on the start up files. It's complicated.)

Details on umask can be found in your shell's manpage, the umask(2) system-call manpage, or the umask(1posix) POSIX-provided utility manpage (if you have the manpages-posix installed).

Answer 3

I found this solution that worked for me. For folders and subfolders:

chmod -R 777 */

And for all files (also in folders and subfolders):

find . -type f -name "*" | xargs chmod 644

All comments welcome if this is not a good way of doing it. I just started learning Linux.
