# Send standard error to standard output (the screen)
# then sends both to the file and to the screen
tdarwin 2>&1 | tee $fdrwlog

The statement below is still outputting the stuff to the terminal

Code:
tdarwin 2>&1 > $fdrwlog

tdarwin 2>&1 | tee $fdrwlog is working great, however no log file is created using tdarwin 2>&1 > $fdrwlog

Apples and oranges.

Code:
$ cat myTest
echo OUTPUT
echo ERROR >&2
 
$ > file1 ./myTest 2>&1
$ cat file1
OUTPUT
ERROR
 
$ 2>&1 > file1 ./myTest
ERROR
$ cat file1
OUTPUT

I have a ksh script to which I pass an argument

Code:
tdradon -fdsstmod=npt02-sr40-syn-4x3smp.cmod

I have coded these variants like below, with the results following

Code:
  opt=$(print $arg | awk 'BEGIN {FS="="} {print $1}')
  print "opt1 = $arg $opt"
  opt=` print $arg | awk 'BEGIN {FS="="} {print $1}' `
  print "opt2 = $arg $opt"
  opt=` print $arg | awk 'BEGIN {FS="="} {print $1}' `
  print "opt3 = $arg $opt"
  opt=` echo "-fdsstmod=npt02-sr40-syn-4x3smp.cmod"  \
        | awk 'BEGIN {FS="="} {print $1}' `
  print "opt4 = $arg $opt"

Code:
opt1 = -fdsstmod=npt02-sr40-syn-4x3smp.cmod dsstmod
opt2 = -fdsstmod=npt02-sr40-syn-4x3smp.cmod dsstmod
opt3 = -fdsstmod=npt02-sr40-syn-4x3smp.cmod dsstmod
opt4 = -fdsstmod=npt02-sr40-syn-4x3smp.cmod -fdsstmod

As one can see, for some reason the -f is removed and am only getting dsstmod when using print rather than -fdsstmod.

Huh ?
Have you anything to support that bizarre (to say the least) HP-UX theory ?

IMO it should be:
Code:
> ... 2>&1

also on HP-UX
