 ------------
 
  -- Command: test expression
      Evaluate EXPRESSION and return zero exit status if result is true,
      non zero status otherwise.
 
      EXPRESSION is one of:
 
      STRING1 '==' STRING2
           the strings are equal
      STRING1 '!=' STRING2
           the strings are not equal
      STRING1 '<' STRING2
           STRING1 is lexicographically less than STRING2
      STRING1 '<=' STRING2
           STRING1 is lexicographically less or equal than STRING2
      STRING1 '>' STRING2
           STRING1 is lexicographically greater than STRING2
      STRING1 '>=' STRING2
           STRING1 is lexicographically greater or equal than STRING2
      INTEGER1 '-eq' INTEGER2
           INTEGER1 is equal to INTEGER2
      INTEGER1 '-ge' INTEGER2
           INTEGER1 is greater than or equal to INTEGER2
      INTEGER1 '-gt' INTEGER2
           INTEGER1 is greater than INTEGER2
      INTEGER1 '-le' INTEGER2
           INTEGER1 is less than or equal to INTEGER2
      INTEGER1 '-lt' INTEGER2
           INTEGER1 is less than INTEGER2
      INTEGER1 '-ne' INTEGER2
           INTEGER1 is not equal to INTEGER2
      PREFIXINTEGER1 '-pgt' PREFIXINTEGER2
           INTEGER1 is greater than INTEGER2 after stripping off common
           non-numeric PREFIX.
      PREFIXINTEGER1 '-plt' PREFIXINTEGER2
           INTEGER1 is less than INTEGER2 after stripping off common
           non-numeric PREFIX.
      FILE1 '-nt' FILE2
           FILE1 is newer than FILE2 (modification time).  Optionally
           numeric BIAS may be directly appended to '-nt' in which case
           it is added to the first file modification time.
      FILE1 '-ot' FILE2
           FILE1 is older than FILE2 (modification time).  Optionally
           numeric BIAS may be directly appended to '-ot' in which case
           it is added to the first file modification time.
      '-d' FILE
           FILE exists and is a directory
      '-e' FILE
           FILE exists
      '-f' FILE
           FILE exists and is not a directory
      '-s' FILE
           FILE exists and has a size greater than zero
      '-n' STRING
           the length of STRING is nonzero
      STRING
           STRING is equivalent to '-n STRING'
      '-z' STRING
           the length of STRING is zero
      '(' EXPRESSION ')'
           EXPRESSION is true
      '!' EXPRESSION
           EXPRESSION is false
      EXPRESSION1 '-a' EXPRESSION2
           both EXPRESSION1 and EXPRESSION2 are true
      EXPRESSION1 EXPRESSION2
           both EXPRESSION1 and EXPRESSION2 are true.  This syntax is not
           POSIX-compliant and is not recommended.
      EXPRESSION1 '-o' EXPRESSION2
           either EXPRESSION1 or EXPRESSION2 is true
