octave:1> gnuplot_binary="/bin/cat"
gnuplot_binary = /bin/cat
octave:2> a=1:100;gplot(a')
octave:3> set data style lines
pl "C:ŠÜCygwinŠÜ/tmp/oct-6106b22d.3" t "line 1"

However taking address@hidden suggestion...

octave:1> putenv('TMPDIR','c:/cygwin/tmp')
octave:2> gnuplot_binary = "/bin/cat"
gnuplot_binary = /bin/cat
octave:3> a = 1:100; gplot(a')
octave:4> set data style lines
pl "c:/cygwin/tmp/oct-6106b22d.7" t "line 1"

works fine.

Many thanks to you both.
