unix commands in Informatica command task - what am I missing?

Question

I tried a simple

if [ 1 == 1 ]; then echo "Hi"; fi >>/projects/ods/Chk.txt
included in the command task but it fails with error code 512....

what am I missing here?

Answer 1

An if/fi block cannot redirect output.

use

if [ 1 == 1 ]; then echo "Hi">>/projects/ods/Chk.txt; fi
As you indicate this is a simple test case, if you need output from a larger block of if/the/else/fi or other logic, you can wrap it all in a process group and redirect that output..

{
   if [ 1 == 1 ]; then 
     echo "Hi"
   else
     echo "nope" 
   fi 
} >>/projects/ods/Chk.txt

Also, it's likely that using == is a problem. Typically you'd use 1 -eq 1 or other constructs like if true ; then, or if you really want good math comparisons, use if (( 1 == 1 )) ; then ..., but older shells may or may not support the (( ... )) test.
