Hi I am writing a ksh script and I am having a problem with a if =
statement. when I run the script you need to put a argument on the =
command line. So inside the script I try to make sure that a user is =
putting a argument on the command line with a if command. The if =
command is below:
if [$1 -z ]
then
echo "you must put a argument on the command line."
exit
fi
the if statement work fine if there no argument. it will print out the =
echo statement. On the other handif I put a argument on the command =
line it will print out the argument and say command is not found.=20
example of command line and statement
$command argument
print out to screen
argument is not found
I have done ksh scripting on a hp-us machine and I never had this =
problem before. Has it something how the Unix machine is setup. It =
seems like the machine does not like any thing that is not a command. It =
does the same thing if I assign a variable. in the program. So the =
program is fine if I do no error checking i.e unix command only , but if =
I use any ksh scripting command it seems to work different.
If anyone can help please email back
Thanks
