Re: [CentOS] Changing UID numbers

In article 2f86eabc-697f-4f57-3a0a-f2e5da13d9d7@nist.gov, Chris Schanzle via CentOS centos@centos.org wrote:

My guess is you used something like

find -uid=500 -exec chown 1000 {} ;

This will start a chown process for each file, changing only one file at a time.  That's a lot of work the system has to do for each file!  But you probably know chown (and similar utilities) can take multiple file arguments, and 'find' can help you take advantage grouping many arguments with the '+' operator to -exec:

find -uid=500 -exec chown 1000 {} +

Well I never knew that! Thanks. For many years I have been doing: find ... -print0 | xargs -0 ...

Ah, I see the newer syntax was introduced in CentOS 5. :-)
