What's wrong with this simple statement?

Shell Programming and Scripting
1

I know that this is a ridiculously simple statement, but I am getting an error when I execute it, and I can't figure out what it is. Can anyone point me in the right direction?

#!/bin/ksh
integer dateMonth=0
integer intZero=0
if [$dateMonth == $intZero]
  then
    dateMonth = 1
fi
echo $dateMonth
2

if [$dateMonth == $intZero]

needs to be

if [ $dateMonth == $intZero ]

Notice the spaces after "[" and preceeding "]"

I've actually tried that, with no success. The error I get is "dateMonth: not found". It then proceeds to echo "0".

4

dateMonth = 1

No spaces around the equals sign

5

When I take out those spaces, the error I get is "[0: not found". And then it still proceeds to echo "0".

Sorry I didn't notice this as well.

dateMonth = 1

needs to be

dateMonth=1

either

if [ $dateMonth -eq $intZero ]

OR

if (( dateMonth = intZero ))

Integer typing is needed in programming languages. Shell scripts no support is there for it. Try as,

#!/bin/ksh
# let assings value to that variable
let dateMonth=0
let intZero=0

# Space needed [[<space> and <space>]]
if [[ $dateMonth -eq $intZero ]]
then

# Don't put space between =, variable and data
    dateMonth=1
fi
echo $dateMonth

Execute this. It will work. Plz. refer more online ksh scripting docs before starting it.

All the best.

HTH.
