The jar command, which process what really is a .zip file, specifically says that it can do an eXtract from stdin. It can also output to stdout. Example (from Linux) === [john.mck...@it-mckownjohn2 ~]$ jar c base.init.plsql.bkup >x.zip [john.mck...@it-mckownjohn2 ~]$ cat x.zip | jar t META-INF/ META-INF/MANIFEST.MF base.init.plsql.bkup === I don't know if this means that the jar command, in this instance, buffers the entire file in memory or not. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
