linux - Bash command to exit from TL1 terminal -

-

i have bash script telnets system's tl1 terminal , executes command how exit out of tl1 terminal?

i've tried quit , exit , doesn't work. normally, press ctrl+c if had logged in manually tl1 term , work; how automate process? 

    #!/bin/bash      (        echo "act-user::root:d::root;"        echo "^c"        echo "quit"        echo "exit"     ) | telnet 192.168.1.1      echo "done"     exit

expect, tool script interactive programs that's part of linux distributions may help. fiddling required, goes this:

#!/usr/bin/expect -f spawn telnet 192.168.1.1 send "act-user::root:d::root;\r" send \003

which start telnet host , send command string followed control-c. expect has many more possibilities (especially fact can react other side replies, possibility limit script runtime, etc), , there literally hundreds of references on internet, should started.

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...
