what is the syntax error in this

Code:

if [[ ${CYC_DT} -ge ${cur_sys_dt}]]; then
  echo "cycle date is equal"
else
  echo "not equal"
fi

t.ksh[120]: Syntax error at line 283 : `then' is not expected.

Thanks

That depends on the contents of the two variables. You may also want to insert a space before "]]".

I believe I've fixed most of the syntax errors below. You are also testing to see if $CYC_DT is greater or equal to $cur_sys_dt but then reporting that it is just equal, use -eq if you want to test equality between numbers. Also if either of these variables don't have a value then you'll get a syntax error. Otherwise it's fine

Code:

if [ $CYC_DT -ge $cur_sys_dt ]
then
   echo "cycle date is equal"
else
   echo "not equal"
fi

I always enclose variables in conditions double-quotes to avoid semantic changes, depending on the variable content. (For SQL, you would say to avoid SQL injection.)

Code:

if [ "$CYC_DT" -ge "$cur_sys_dt" ]
