This will work only so long as the process generating the output doesn't generate enough data to fill a pipe buffer. Since your "null" program isn't actually going to read anything, when the pipe fills, the writing program will block. A more reasonable method would be to use "|cat >/dev/null", though the result is the same as a simple ">/dev/null". Why did you want the pipe, anyway? Les Mikesell les@chinet.chi.il.us
