Full Discussion: Expect Script - While file exist
Top Forums UNIX for Dummies Questions & Answers Expect Script - While file exist Post 302244912 by ramen_noodle on Thursday 9th of October 2008 02:54:41 AM

Since you are driving the interaction remotely and possibly dealing with multiple logins concurrently the way I'd do this is to use an interact for each spawn_id (after successful setup) with a procedure that periodically polls the remote filesystem, makes the necessary changes and informs you of completion or error.

Here is a basic example from some code I wrote several years ago. You may want to check the interact examples out at the expect site and at active state.
Code:
spawn -noecho ssh -X root@$host


                       expect {
		                 
		              -re ".*asswor.*" {
			                   send $credentials\r\n
					   if {[info exists initcmd] && [string length $initcmd]} {send "$initcmd\r\n"}
					   if {[info exists cmdfile] && [string length $cmdfile]} {after 1000; feedCmdfile $spawn_id}
					   userMenu; stty echo
					   interact {
					             "~QQ" {rmvConnection $spawn_id}
						     "~AA" {
						           send_user "\nHostname: "
							   expect_user -re "(.*)\r.*" {set hostname $expect_out(1,string)}
							   send_user "\nUser: "
							   expect_user -re "(.*)\r.*" {set username $expect_out(1,string)}
							    if {![string compare [set id [addConnection $username $hostname]] "NUL"] == 0} {
							         iactInner $id
							    } else {
							           send_user "Connection to $hostname failed\n"
							    }	    
						           }
					             "~AF" {doFileAppend $spawn_id}		   		    
						     "~DF" {}
						     "~UF" {}
						     "~XX" {enterInterp $spawn_id}
						     "~MM" {userMenu}
				          }		     
			      }
			      
			      -re ".*\(yes.*no\)" {
			                   send "yes\r\n"
					   exp_continue
			      }
			      
			      -re ".*(#|>).*"  {
			      			if {[info exists initcmd] && [string length $initcmd]} {send "$initcmd\r\n"}
					        if {[info exists cmdfile] && [string length $cmdfile]} {after 1000; feedCmdfile $spawn_id}
					             userMenu; stty echo
					             interact {
					             "~QQ" {rmvConnection $spawn_id}
						     "~AA" {
						           send_user "\nHostname: "
							   expect_user -re "(.*)\r.*" {set hostname $expect_out(1,string)}
							   send_user "\nUser: "
							   expect_user -re "(.*)\r.*" {set username $expect_out(1,string)}
							    if {![string compare [set id [addConnection $username $hostname]] "NUL"] == 0} {
							         iactInner $id
							    } else {
							           send_user "Connection to $hostname failed\n"
							    }	    
						           }		    
						     "~DF" {}
						     "~UF" {}
						     "~XX" {enterInterp $spawn_id}
						     "~MM" {userMenu}
				          }		     
			      }
			      
			      eof {send_user "remote connection for $host has failed\n"}
			      timeout {send_user "Could not connect to $host..connect() timed out\n"}
		     }
