Re: Redirecting STDOUT and standard error to file

googling for "tee exit code" i found this that works (source):

(/bin/foo ; echo $? >RES)| tee -a $LOGFILE
export ERR=$(cat RES)
[download]

I also found this posting (see also man bash and search for PIPESTATUS) that says that this will work:

  $ cat test
  #!/bin/bash
  echo foo
  sleep 2
  echo bar
  false
  
  $ ./test | tee blah
  foo
  [.. seconds later..]
  bar
  
  $ echo ${PIPESTATUS[@]}
  1 0

  # (so ${PIPESTATUS[0]} should give you the return of the first comma
+nd).

But i was unable to get it to work (PIPESTATUS seemed to always have just one element of 0)...

`PIPESTATUS` works for me. `$ uname -s -r FreeBSD 5.4-RELEASE $ bash --version GNU bash, version 2.05b.0(1)-release (i386-portbld-freebsd4.8) Copyright (C) 2002 Free Software Foundation, Inc.` [download] `man bash` extract: `PIPESTATUS` An array variable (see Arrays below) containing a list of exit status values from the processes in the most-recently-executed foreground pipeline (which may contain only a single command).
