Chmod recursively

Question

I have an archive  which is archived by someone else  and I want to automatically  after I download it  to change a branch of the file system within the extracted files to gain read access   I can t change how archive is created    I ve looked into this thread  chmod  How to recursively add execute permissions only to files which already have execute permission as into some others  but no joy   The directories originally come with multiple but all wrong flags  they may appear as   drwx------ d---r-x--- drwxrwxr-x dr--r-xr--   Those are just the few I ve discovered so far  but could be more   find errors when tries to look into a directory with no x permission  and so doesn t pass it to chmod  What I ve been doing so far  is manually change permissions on the parent directory  then go into the child directories and do the same for them and so on  But this is a lot of hand labour  Isn t there some way to do this automatically   I e  how I am doing it now   do     chmod -R  x   chmod -R  r   until I get no errors  then    find -type f -exec chmod -x        But there must be a better way

You need read access  in addition to execute access  to list a directory  If you only have execute access  then you can find out the names of entries in the directory  but no other information  not even types  so you don t know which of the entries are subdirectories   This works for me   find   -type d -exec chmod  rx

You can use chmod with the X mode letter  the capital X  to set the executable flag only for directories   In the example below the executable flag is cleared and then set for all directories recursively      mkdir foo    mkdir foo bar    mkdir foo baz    touch foo x    touch foo y     chmod -R go-X foo     ls -l foo total 8 drwxrw-r-- 2 wq wq 4096 Nov 14 15 31 bar drwxrw-r-- 2 wq wq 4096 Nov 14 15 31 baz -rw-rw-r-- 1 wq wq    0 Nov 14 15 31 x -rw-rw-r-- 1 wq wq    0 Nov 14 15 31 y     chmod -R go X foo     ls -l foo total 8 drwxrwxr-x 2 wq wq 4096 Nov 14 15 31 bar drwxrwxr-x 2 wq wq 4096 Nov 14 15 31 baz -rw-rw-r-- 1 wq wq    0 Nov 14 15 31 x -rw-rw-r-- 1 wq wq    0 Nov 14 15 31 y   A bit of explaination    chmod -x foo - clear the eXecutable flag for foo chmod  x foo - set the eXecutable flag for foo chmod go x foo - same as above  but set the flag only for Group and Other users  don t touch the User  owner  permission chmod go X foo - same as above  but apply only to directories  don t touch files chmod -R go X foo - same as above  but do this Recursively for all subdirectories of foo
