batch file - How to make two running command-prompt windows send commands to each other on the same computer? -

-

i new using command-prompt programming related purposes if makes no sense or seems unclear please request elaborate , best.

what hoping able have 2 command-prompt windows open on windows machine (running windows 7) , have them communicate each other. instance want cmd window tell cmd window b print contents of file , vice versa.

is in anyway possible? also, know there may way polling file in 1 command-prompt window, asynchronous/non-blocking way of doing if possible.

thanks in advance!

i found quite simple make 2 command windows interact each other.

batch file 1:

:keepsending set /p message= echo set run=%message% >command.bat goto :keepsending

batch file 2:

:running %run% set ran=%run% :check if not "%ran%"=="%run%" goto :running call command.bat timeout 1 >nul goto :check

add in counter on , guess make work in longer code interacts each other.

if want work on network use poshd/popd

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
