通過從cygwin的一個python腳本

Question

我試圖得到這個工作運行rsync命令，但我不斷收到

subprocess.call(['c:/cygwin/bin/bash.exe', '--login', '-i', 'rsync', '-zrgo', '--omit-dir-times', '--verbose', '--delete', '.', 'usertwo@192.168.1.1:/var/www/project/']) 

-

bash: /usr/bin/rsync: cannot execute binary file 
126

你缺少了 '-c'（命令）選項打擊。你還應該提供rsync命令作爲一個字符串：

subprocess.call(['c:/cygwin/bin/bash.exe', '--login', '-i', '-c', 'rsync -zrgo --omit-dir-times --verbose --delete . usertwo@192.168.1.1:/var/www/project/']) 

從手冊頁：

-c string If the -c option is present, then commands are read from 
      string. If there are arguments after the string, they are 
      assigned to the positional parameters, starting with $0. 

例如：

# bash /bin/ls 
/bin/ls: /bin/ls: cannot execute binary file 
# bash -c "/bin/ls -l" 
<ls output>
