Hi all, Here's a quick one...
The following works as expected: # exec 9<>test.file ; jot 50 >&9 ; tail -5 <&9 9>&- 46 47 48 49 50 The next one does not: # exec 9<>test.file ; jot 50 >&9 ; head -5 <&9 9>&- # The question is: Why? bash --version GNU bash, version 3.2.17(1)-release (i386-apple-darwin9.0) Copyright (C) 2005 Free Software Foundation, Inc. I'd like to "split" output from a pipe to perform multiple end-steps after a long-chain of pipes. FD redirection seems to be the best way. Many thanks in advance for any ideas as to why "head" doesn't work and "tail" does. Thanks SM
