GPIV_UHISTO(1) General Commands Manual GPIV_UHISTO(1)NAME
gpiv_uhisto - Tests PIV data by printing/displaying an histogram of the horizontal particle displacements.
SYNOPSIS
gpiv_uhisto [-g] [-h | --help] [-n N] [-p | --print] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
Gpiv_uhisto calculates the histogram of the horizontal particle displacement distribution between minimum and maximum values.
The parameters read from the configuration resources (containing the key VALID) may be overruled by the command line options, as explained
below.
Options-g Graphical visualization of the histogram with gnuplot.
-h | --help
On-line help
-n N Override number of bins (default 10, hard coded).
-p | --print
Print parameters, command line options and eventually used input and output filenames to stdout. The output is identic of file-
name.par, in case -f is used.
-v | --version
Print version information on standard output, then exit successfully.
filename
Input PIV file. Overrides stdin and stdout. Output will be written to filename.pdf. The parameters will be written or appended to
filename.par and may be used for future use by including them in ./gpivrc.
SEE ALSO
gpivtools
NOTES
stdin and stdout has still to be implemented. [-f filename ] will be added.

Gerber Van der Graaf
BUGS
The program seems to work fine with real PIV data. So far, no serious bugs have been found.

GPIV_FASTY(1) General Commands Manual GPIV_FASTY(1)NAME
gpiv_fasty - Simple data manipulation tool for PIV data.
SYNOPSIS
gpiv_fasty [-h | --help] [-p | --print] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
gpiv_fasty returns fast running y-positions of data that are originally written with fast running x-positions. All other variables (parti-
cle displacements, snr, peak#) are at the new positions as well.
The parameters read from the configuration resources (containing the key POST) may be overruled by the command line options, as explained
below.
Options-h | --help
On-line help.
-p | --print
Prints parameters, command line options and input and output filenames to stdout. The output is identic of filename.par, in case -f
is used.
-v | --version
Print version information on standard output, then exits successfully.
filename
Input Piv data file. Overrides stdin and stdout. Output will be written to filename.ma.piv. The parameters will be written or
appended to filename.par and may be used for future use by including them in ./gpivrc.

hi,
how does a program know whether some data are available from stdin?
I would like to make a program which could read its data from stdin
and _if_there_is_nothing_at_stdin_ from a file which name is given
as an argument. If there is nothing in stdin and no filename is given as
argument,... (2 Replies)

I need to implement a pure virtual FSM program design which copies stdin to stdout, converting any C trigraphs found to their single character form (e.g. converting trigraph ??= to #) including those in the comments.
