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.
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
