Usage:     pcretest [options] [<input file> [<output file>]]

Input and output default to stdin and stdout.
This version of pcretest is not linked with readline().

Options:
  -16      use the 16-bit library
  -32      use the 32-bit library
  -b       show compiled code
  -C       show PCRE compile-time options and exit
  -C arg   show a specific compile-time option and exit
           with its value if numeric (else 0). The arg can be:
     linksize     internal link size [2, 3, 4]
     pcre8        8 bit library support enabled [0, 1]
     pcre16       16 bit library support enabled [0, 1]
     pcre32       32 bit library support enabled [0, 1]
     utf          Unicode Transformation Format supported [0, 1]
     ucp          Unicode Properties supported [0, 1]
     jit          Just-in-time compiler supported [0, 1]
     newline      Newline type [CR, LF, CRLF, ANYCRLF, ANY]
     bsr          \R type [ANYCRLF, ANY]
  -d       debug: show compiled code and information (-b and -i)
  -dfa     force DFA matching for all subjects
  -help    show usage information
  -i       show information about compiled patterns
  -M       find MATCH_LIMIT minimum for each subject
  -m       output memory used information
  -O       set PCRE_NO_AUTO_POSSESS on each pattern
  -o <n>   set size of offsets vector to <n>
  -p       use POSIX interface
  -q       quiet: do not output PCRE version number at start
  -S <n>   set stack size to <n> megabytes
  -s       force each pattern to be studied at basic level
  -s+      force each pattern to be studied, using JIT if available
  -s++     ditto, verifying when JIT was actually used
  -s+n     force each pattern to be studied, using JIT if available,
             where 1 <= n <= 7 selects JIT options
  -s++n    ditto, verifying when JIT was actually used
  -t       time compilation and execution
  -t <n>   time compilation and execution, repeating <n> times
  -tm      time execution (matching) only
  -tm <n>  time execution (matching) only, repeating <n> times
  -T       same as -t, but show total times at the end
  -TM      same as -tm, but show total time at the end
