If "truncate" is not available this should do the trick: find . -type f -name "log*" -print0 | xargs -0 -i /bin/sh -c 'echo -n "" > {}'

You guys are forgetting the -exec flag on find. Try this: find . -type f -name '*.log' -exec tee {} </dev/null \; Or, if you have truncate (I don't, and it doesn't seem to be in the Ubuntu repos): find . -type f -name '*.log' -exec truncate -s 0 {} \;

find . -type f -name '*.log' -exec cp /dev/null '{}' \; Handles spaces in file names (never assume filenames won't have spaces in them).
