How to 'echo "" > x' on multiple files

Solution 1:

You don't need the echo. Just

>filename

will empty the file. To edit rassie...

for FILE in *.log
do
   >"${FILE}"
done

The quotes and brackets are preferred, as they will correctly handle files with spaces or special characters in them.

Solution 2:

Just for fun, another variation combining Eric Dennis' find with everybody else's redirection:

find . -name "*.log" -exec sh -c ">{}" \;
