NAME

       dirfile2ascii — output dirfile database vectors as ASCII text

SYNOPSIS

       dirfile2ascii [ OPTION ]... DIRFILE [ [ -a | -A | -e | -E | -F | -g | -G | -o | -i | -u | -x | -X ] FIELD
              ]...

DESCRIPTION

       Fetches  data  from a dirfile(5) database specified by DIRFILE and writes it as ASCII to standard output.
       Any number of vector FIELDs may be specified.  Each specified field is printed in a separate column.

       Mandatory arguments to long options are mandatory for short options too.

       -d, --delimeter=delim
              separate columns by delim.  (Default: a single space.)

       -f, --first-frame=first_frame-last_frame
              read from frame first_frame to frame last_frame (inclusive).

       -f, --first-frame=first_frame:nframes
              equivalent to --first-frame=first_frame --num-frames=nframes.

       -f, --first-frame=first_frame
              If first_frame >= 0, start reading  at  frame  first_frame.   If  first_frame  is  -1  and  --num-
              frames=nframes  is  specified,  read  the last nframes frames.  If --first-frame is not specified,
              reading starts at frame zero.

       -n, --num-frames=nframes
              read at most nframes frames.  If not specified, or if nframes = 0, all frames to the  end-of-field
              are read.

       -p, --precision=format
              use format to format output.  format may contain any of the flag characters, a field width, and/or
              a precision as specified in printf(3).  It may not contain a length modifier.

       -q, --quiet
              don't write diagnostic messages on standard error.  (This is the default behaviour).

       -s, --skip=frame_skip
              if frame_skip > 0, output only one sample for every frame_skip frames.

       -v, --verbose
              write diagnostic messages on standard error.

       -z, --fill=STRING
              Fill  columns  which go past the end of their corresponding field with the string STRING.  The de‐
              fault behaviour is to fill columns with floating-point conversions with NaN and columns with inte‐
              ger conversion with 0, which mirrors what occurs when an attempt is made to print data from before
              the start of a field.  (Note: the default behaviour cannot be reproduced with this  option,  since
              STRING is applied to all columns, regardless of conversion type.)

       In  addition to the above, each FIELD argument may be preceded by a short option, one of: -a, -A, -e, -E,
       -F, -g, -G, -i, -o, -u, -x, -X, indicating the conversion to be used.  See printf(3) for the  meaning  of
       these  conversion  specifiers.  The output flags, width, and precision may be specified by using --preci‐
       sion.  If no conversion specifier is given, %f is used.

       For conversion specifiers %a, %A, %e, %E, %f, %F, %g, %G, data is read from the dirfile as double  preci‐
       sion floats.  For conversion specifier %i, data is read as 64-bit signed integers.  For conversion speci‐
       fiers %o, %u, %x, %X, data is read as 64-bit unsigned integers.

LIMITATIONS

       No  native  support for printing complex data is provided.  This may be worked around by using dirfile(5)
       representation suffixes.  For example, the command

              dirfile2ascii DIRFILE FIELD.r FIELD.i

       will print the real and imaginary parts of the complex  valued  field  FIELD  in  the  first  and  second
       columns, respectively.
