batch execution and mkfifo

[woche]

hi

i'm trying to set up a named pipe, stuff in some commands and - from another programm - execute the commands in the pipe. i thought, that after execution of the pipe, the pipe itself would die (disappear) - but mine doesn't:

<< program 1 >>
mkfifo MYPIPE
'ps -ef' > MYPIPE &

...some time later
<< program 2>>
cat MYPIPE

-> this returns me the output of ps -ef but MYPIPE remains in the directory.

what am i doing wrong?

thx!
woche

p.s.: all of this is on aix 4.3

Hi:

I've never heard of a named pipe disappearing on it own. I think you need to delete it - probably after you're done reading it in program2.
