Re: 'run xterm' fails to open a window

[jean-luc malet <jeanluc dot malet at gmail dot com>]

thanks for the reply
I tested doing
c:\Cygwin\bin\run.exe sh -c "env|grep DISP > /cygdrive/c/log"
I get the expected value : DISPLAY=:0.0
C:\cygwin\bin\run.exe -p /usr/bin sh -c "gvim > /cygdrive/c/log 2>&1"
do diplay waring in the log.... but does make the window appears
in fact  it seems that because gvim do output some error string it is
stopped by run.exe....

so as said in next reply
C:\cygwin\bin\run.exe -p /usr/bin sh -c "gvim >/dev/null 2>&1" is a workaround

thanks
JLM
