No idea what STEP_EXECUTE is. What type of script is this?

Typically, you might use something like the following for file existence checks:

Code:
if [ -f $filename ]
then
  do somethine
fi

To start with, UNIX isn't a language, it's an operating system. There are many languages that will run on a Unix/Linux system which will have different syntax. For this forum, we're talking shell scripting. There are at least a couple of options:

Code:
if [ $a -eq 1 ] && [ $b -eq 1 ]
then
  echo do something
fi

or

Code:
if [ $a -eq 1 -a $b -eq 1 ]
then
  echo do something
fi
