, execute the sas program.

How about

Code:

if [ -f ./file2 -a  -f ./file3 -a \( -f ./file1 -o $DAYOFWEEK -ne 1 \) ]  
  then  sas 1 /files/are/here/process.sas
fi

Be aware that the -a and -o operators are deprecated and should be replaced by && and || (but I'm not sure how to do the parentheses grouping).

Can be done as a { } group. (Note: there must be a semicolon or newline before the closing brace! And of cause spaces next to the [ ] { } )

Code:

if [ -f ./file2 ] && [  -f ./file3 ] && { [ -f ./file1 ] || [ $DAYOFWEEK -ne 1  ]; }
  then  sas 1 /files/are/here/process.sas
fi
