Find and Replace

rhansen — Wed, 11 Nov 2009 21:28:24 GMT

Hello,

I have hundreds of files that I need to change the ownerships for. The files are under directory
-rw-rw---- 1 4707 arbor 570 Oct 29 20:03 /opt/hyperion/parmfiles/arbor/ECSDM_INCFC_CCHD_CRNCY_CONV_RATE

I need to change the files owned by UID 4707 to arbor. I was thinking of using for loop.

Any help would be appreciated.

Thanks.

Let find do the work:

cd /dir/files/are/in
find . -type f -user 4707 -exec chown arbor {} \+

Hi:

Patrick's use of the "+" terminator with the '-exec' command makes things much more efficient than if the '\;' terminator is used.

That is:

# find . -type f -user 4707 -exec chown arbor {} \+

...runs much faster than:

# find . -type f -user 4707 -exec chown arbor {} \;

The '+' syntax causes multiple arguments to be assembled and passed to one instantiation of the 'exec'ed command eliminating the overhead of spawning one process per file.

Lastly, too, you do not need to escape the '+' character and can write:

# find . -type f -user 4707 -exec chown arbor {} +

True. Old habits die hard though.
