something like a universal chmod

**Doctor Feelgood** · Posted: Wed, 15 Dec 2004 10:10:13 Post Subject: something like a universal chmod

OK, so I have a folder where the databases are backed up to on a daily basis. But then they are overwitten each day. I just want to set up a cron similar to my other one where it copies that backup to a folder based on the day of the week, so I have 7 backups at any one time.

But, the permission seem to revert to 600 on that db backup each time it is written. I wind up manually having to change it to 777 to make sure it is accesible for copying, but is there a way I can make this happen automatically?

Grin

- Thanks

just put it in your cron job, chmod 755 dir/*

I tried that... there doesn't seem to be appropriate permissions on this level to do so. So, I logged in as root and setup a separate cron that only does that. Doesn't seem to do anything...

WTF

I now see that I can manually change permissions on this when logged into the server as root, but not when I am logged into the bigbruin area with that separate account... Confused

Sounds like a group problem. Try chgrp'ing it.

Oops, sorry. I meant CHOWN:

chown -R username *

Also, I just thought of recursion in CHMOD. These files are in subdirectories, right? You might need to use the -R flag...

I was just going to suggest using the -R option.

If that doesn't work, who are the owner and group of the directory and the backup files.

yes, files in a subdirectory.

I am unsure about ownership... the whole server is mine, so it is either my root login or the site specific one.

so... how do I use -R with chmod? just: chmod -R 777 filename

And what is that actually doing? Do I do that once, or do I need to do it as a cron?

thanks!

Copying from man pages....

the command sequence:

chmod -R 777 f*

will change permissions on:

./dir1/fdir2

./dir1/fdir2/file1

./dir1/fdir2/file2

./dir1/file3

I hate using chmod recursevly as it sets everything (including files) to whatever permissions you might just want on your directories, and vice versa.

This works for me:

cd /some/location && find . -type d -exec chmod 755 {} \; && find . -type f -exec chmod 644 {} \;

I use it to keep things sane in my file storeage area.
