Or am I doing (or expecting?) something wrong?
I've boiled my script down quite a bit to isolate the behavior. The
code is at the bottom.
Ignore the output for LIST in the this, I was also trying to isolate a
problem with that not behaving the way I expect, but while isolating
the problem with TYPE, I actually eliminated the problem with LIST. If
I can reproduce the LIST problem maybe I'll send another question later.
This is the output I get with the OpenSolaris ksh93:
[kmcdon...@galileo] 297> ./Test1.sh
:TYPE=None :LIST=Zero:
Main :TYPE=None :LIST=Zero:
Func1 :TYPE=None :LIST=Zero:
Func1 :TYPE=RIGHT :LIST=Zero:
Func2 :TYPE=RIGHT :LIST=Zero:
Func2 :TYPE=WRONG!:LIST=Zero One:
Func2 :TYPE=WRONG!:LIST=Zero One:
Func2 :TYPE=WRONG!:LIST=Zero One Two:
Func1 :TYPE=WRONG!:LIST=Zero One Two:
Main :TYPE=WRONG!:LIST=Zero One Two:
:TYPE=WRONG!:LIST=Zero One Two:
However I expected to see what bash and /bin/ksh (88??) give below:
(/export/Install/src/bin)
[kmcdon...@galileo] 298>bash ./Test1.sh
:TYPE=None :LIST=Zero:
Main :TYPE=None :LIST=Zero:
Func1 :TYPE=None :LIST=Zero:
Func1 :TYPE=RIGHT :LIST=Zero:
Func2 :TYPE=RIGHT :LIST=Zero:
Func2 :TYPE=WRONG!:LIST=Zero One:
Func2 :TYPE=RIGHT :LIST=Zero One:
Func2 :TYPE=WRONG!:LIST=Zero One Two:
Func1 :TYPE=RIGHT :LIST=Zero One Two:
Main :TYPE=RIGHT :LIST=Zero One Two:
:TYPE=RIGHT :LIST=Zero One Two:
(/export/Install/src/bin)
[kmcdon...@galileo] 299>ksh ./Test1.sh
:TYPE=None :LIST=Zero:
Main :TYPE=None :LIST=Zero:
Func1 :TYPE=None :LIST=Zero:
Func1 :TYPE=RIGHT :LIST=Zero:
Func2 :TYPE=RIGHT :LIST=Zero:
Func2 :TYPE=WRONG!:LIST=Zero One:
Func2 :TYPE=RIGHT :LIST=Zero One:
Func2 :TYPE=WRONG!:LIST=Zero One Two:
Func1 :TYPE=RIGHT :LIST=Zero One Two:
Main :TYPE=RIGHT :LIST=Zero One Two:
:TYPE=RIGHT :LIST=Zero One Two:
Here's the code. Shouldn't the 'typeset TYPE' in Func2 make TYPE a
local variable for that function only? I expected it to hide the
global TYPE, but it shouldn't change the global TYPE, should it?
(/export/Install/src/bin)
[kmcdon...@galileo] 300>cat Test1.sh
#!/bin/ksh93
TYPE="None "
LIST="Zero"
Main()
{
echo "Main :TYPE=${TYPE}:LIST=${LIST}:"
Func1 "$...@}"
echo "Main :TYPE=${TYPE}:LIST=${LIST}:"
}
Func1()
{
echo "Func1 :TYPE=${TYPE}:LIST=${LIST}:"
TYPE="RIGHT "
echo "Func1 :TYPE=${TYPE}:LIST=${LIST}:"
Func2 One
Func2 Two
echo "Func1 :TYPE=${TYPE}:LIST=${LIST}:"
}
Func2()
{
echo "Func2 :TYPE=${TYPE}:LIST=${LIST}:"
LIST="${LIST} ${1}"
typeset TYPE="WRONG!"
echo "Func2 :TYPE=${TYPE}:LIST=${LIST}:"
}
echo " :TYPE=${TYPE}:LIST=${LIST}:"
Main "$@"
echo " :TYPE=${TYPE}:LIST=${LIST}:"
Am I nuts?
Thanks!
