Script-kiddies,
How can I write a wrapper that filters stderr (fd 2) without altering
stdout (fd 1) using ksh?
Detail:
ksh> func 2>/devnull
This is desired from stdout.
ksh> func 1>/dev/null
This is desired from stderr
This is undesired from stderr
This is more desired from stderr
ksh> func-wrapper 2>/dev/null
This is desired from stdout
ksh> func-wrapper 1>/dev/null
This desired from stderr
This is more desired from stderr
ksh> cat func-wrapper
#!/bin/ksh
????
func $*
????
What should the ???? be?
TIA,
--
