exp_continue가있는 대상이 누락 되었습니까?

나는 스위치로 ssh를 할 수있게 해주는 expect 스크립트를 작성하고, 플래시의 특정 소프트웨어 세트를 찾은 다음 삭제한다. 나는 결과 "A"가 "B"를, 결과 "C"가 "B"를 보았다고 말하고 싶습니다. 하나의 명령을 실행하면 이러한 모든 결과가 표시됩니다.exp_continue가있는 대상이 누락 되었습니까?

이것은 내가 예상 한 결과의 예입니다.

내가 찾고있는 것은 "flash1 :"디렉토리입니다. 이제 총 9 개의 플래시 파일 시스템이 될 가능성이 있습니다. 항상 "flash1 :"을 갖습니다. 내가하고 싶은 일은 각각의 가능한 디렉토리로 가서 파일이나 전체 디렉토리를 삭제하는 것입니다. 그리고 만약 그들이 다른 디렉토리를 옮기고 싶지 않다면.

내가 알고 싶은 것은 exp_continue를 올바르게 사용하는 방법 또는이 인스턴스에서 전혀 사용해야하는 경우입니다. 이것은 내가 작성한 것이며, 소프트웨어를 flash1에 복사하지만, flas2 등이 존재하면 다른 플래시에 소프트웨어를 복사하거나 삭제하지 않아도됩니다.

내가 말할 것이다 :

set flash_dirs {} 
send "dir ?\r" 
expect { 
    -re {\m(flash[1-9])\M} { 
     lappend flash_dirs $expect_out(1,string) 
     exp_continue 
    } 
    "*#" 
} 
foreach dir $flash_dirs { 
    send "delete /force /recursive $dir:c3750-ipservicesk9-mz.122-55.SE5\r" 
    expect "*#" 
    send "delete /force /recursive $dir:c3750-ipservicesk9-mz.122-55.SE5.bin\r" 
    expect "*#" 
}

그런 다음 당신이 FLASH1에 물건을 복사합니다. 그 후, 나는 디렉토리 목록이 변경되지 않은 가정, 그래서 당신은 이미 탑재 된 플래시 드라이브 알고

foreach dir $flash_dirs { 
    if {$dir eq "flash1"} continue 
    send "copy flash1:c3750-ipservicesk9-mz.122-55.SE7.bin $dir:\r" 
    expect "Destination filename" 
    send "\r" 
    expect "*#" 
}

많은 DRY 어. 물론 안된다.

그래서 어떤 이유에서, 그것은 dir flash를하고 있습니다. (플래시와 flash1은 같은 디렉토리입니다. 번호가 매겨진 유일한 이유는 스택에서 작업중인 스위치를 식별하는 것입니다). 이전 .bin 파일을 삭제하거나 새 .bin 파일을 스택의 다른 구성원에 복사하지 않습니다. – bjforesthowell

스크립트 상단에'exp_internal 1'을 추가하십시오. 기대는 당신에게 무슨 일이 일어나는지 보여줄 것입니다. –

그냥 "dir?"을 계속 반복합니다. 실제로 번호가 지정된 플래시 디렉토리 즉, flash2, flash3 등을 찾고있는 withouth ... 나는 exp_internal의 출력을 파일로 파이프 처리했습니다. 여기에 게시 할 수있는 방법이 있습니까, 아니면 원래 게시물을 편집하여 거기에 올려 놓아야합니까? – bjforesthowell

exp_continue가있는 대상이 누락 되었습니까?
