Shell Programming and Scripting

Huh? Who suggested that you remove one of the two required parameters to your function?

There was a suggestion that you could invoke your script with:

Code:

ksh -x /scripts/testing/mks.ksh

to turn on tracing. And there was a suggestion that you could change your script to:

Code:

#!/bin/ksh
set -x
test_input()
{
Prmshn=${1}
InFLNm=${2}
echo "DEBUG: $Prmshn -- $InFLNm"
if test "$Prmshn" "$InFLNm" ; then
  echo " $Prmshn $InFLNm input file is now available."
else
  echo " $Prmshn $InFLNm input file is not available."
fi
}
test_input -x /input/test.txt

to enable tracing. Or, to make it easier to read and enable tracing, something like:

Code:

#!/bin/ksh
set -x
test_input() {
	Prmshn=${1}
	InFLNm=${2}
	echo "DEBUG: $Prmshn -- $InFLNm"
	if test "$Prmshn" "$InFLNm"
	then	echo " $Prmshn $InFLNm input file is now available."
	else	echo " $Prmshn $InFLNm input file is not available."
	fi
}
test_input -x /input/test.txt

NOTE: I added a space in your echo commands before $Prmshn. Calling echo with a 1st argument that starts with a minus sign produces results that vary radically from system to system!

Using:

Code:

test_input -x /input/test.txt

as the last line in your script is a asking your function to determine whether or not /input/test.txt is an executable file. If you just want to know whether or not/input/test.txt is present on your system, use:

Code:

test_input -e /input/test.txt

If you want to know if /input/test.txt is present and is a regular file, use:

Code:

test_input -f /input/test.txt

If you want to know if /input/test.txt is present and is a directory, use:

Code:

test_input -d /input/test.txt

If you want to know if /input/test.txt is present and is readable, use:

Code:

test_input -r /input/test.txt
