xargs

E.g. to change the permissions of all directories:

find . -type d -print | xargs /bin/chmod ug+rx

To be able to handle directory names with special characters

find . -type d -print0 | xargs -0 /bin/chmod ug+rx

In order to find all tif files in the current directory or below and to compress them (using the ImageMagick "mogrify" command and LZW compression):

find . -name '*.tif' -print | xargs mogrify -compress LZW
