ssh中斷while

 

管理遠程服務器時 不可避免的使用while ，但是當在while下執行循環時 ssh會中斷 ，用for執行就不會出現這種問題

 

 

解決辦法有兩個

 

 

1.用for循環替代 while循環 

 

2. 用while循環時 ，ssh 增加 -n參數 

 

 

 

 man ssh

 

     -n      Redirects stdin from /dev/null (actually, prevents reading from stdin).  This must be used when ssh is

             run in the background.  A common trick is to use this to run X11 programs on a remote machine.  For exam-

             ple, ssh -n shadows.cs.hut.fi emacs & will start an emacs on shadows.cs.hut.fi, and the X11 connection

             will be automatically forwarded over an encrypted channel.  The ssh program will be put in the back-

             ground.  (This does not work if ssh needs to ask for a password or passphrase; see also the -f option.)
