windows - Run program from command line what prompts password and automatically provide password for it (cmd.exe, python) -


i have command line program prompts password:

> cwrsync root@nn.nn.nn.nn:/src /cygdrive/c/dst

output (when run cmd.exe command line):

root@nn.nn.nn.nn's password:

when input password manually, ok. output:

skipping directory src

i want provide password command line or python script automatically.

i tried:

one. command line:

> echo pass|cwrsync -r root@nn.nn.nn.nn:/src /cygdrive/c/dst

not working. output:

root@nn.nn.nn.nn's password:

two. python script. test.py:

import subprocess cmd = "cwrsync -r root@nn.nn.nn.nn:/src /cygdrive/c/dst" proc = subprocess.popen(cmd1, stdout=subprocess.pipe, stderr=subprocess.pipe, stdin=subprocess.pipe, shell=true) std1, std2 = proc.communicate("pass") print std1print std2

not workin. output:

permission denied, please try again. permission denied, please try again. permission denied (publickey,password). rsync: connection unexpectedly closed (0 bytes received far) [receiver] rsync error: unexplained error (code 255) @ io.c(235) [receiver=3.1.1]

it common security oriented programs ask password on direct io instead of reading stdin. , :

echo pass|cwrsync -r root@nn.nn.nn.nn:/src /cygdrive/c/dst

did ask password, presume csrsync directly reads console.

in case cannot automate without work , low level programming, because have simulate keyboard actions. should instead search documentations, because looks uses underlying ssh, accept public key pair. if accept 1 without passphrase, should able automate it.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
