This is because pipes operate in subshells and the exit applies to the subshell. Please see the bash FAQ question E4 for more information. ftp://ftp.cwru.edu/pub/bash/FAQ > cat /tmp/atf | while read; do exit 3; done # for any text file /tmp/atf > Yet the following works > cat /tmp/atf | while read; do exit 3; done Those two are the same. You probably meant to say: while read; do exit 3; done < /tmp/atf No pipeline there and so that is done in the current shell. Bob
