Я пропускаю цель с exp_continue?

Я пытаюсь написать сценарий ожидания, который позволяет мне переключиться на ssh, искать определенный набор программного обеспечения во флеше, а затем удалить его. Я хотел бы сказать, что если вы видите результат «A», выполните действие «B», и если вы увидите результат «C», выполните действие «B». Все эти результаты отображаются, когда я запускаю одну команду.Я пропускаю цель с exp_continue?

Это пример результата, которого я ожидаю.

Что я ищу - это каталог "flash1:". Теперь существует вероятность того, что они будут состоять из девяти флеш-файловых систем. У вас всегда будет «flash1:»; то, что я хочу сделать, - это войти в каждый из возможных каталогов и удалить либо файл, либо весь каталог. И если у них нет других каталогов, просто чтобы двигаться дальше.

Что я хочу знать, как правильно использовать exp_continue, или если мне нужно использовать его вообще в этом случае. Это то, что я написал, и он скопирует программное обеспечение на flash1, но если flas2 и т. Д. Существуют, он не скопирует или не удаляет программное обеспечение на другие вспышки.

Я бы сказал:

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 "*#" 
}

Затем скопировать материал в Flash1. После этого, я полагаю, список реж не изменилось, так что вы уже знаете, какие флэш-диски установлены:

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 "*#" 
}

Много DRY эр. Конечно, непроверенный.

поэтому по какой-то причине он выполняет миксер: (flash и flash1 - это тот же каталог, кстати, единственная причина, по которой он пронумерован, - определить, с каким коммутатором вы работаете в стеке). Он не удаляет старый .bin-файл или не копирует новый .bin-файл другим членам стека. – bjforesthowell

добавьте 'exp_internal 1' в начало вашего скрипта. Ожидание покажет вам, что происходит. –

Он просто продолжает повторять "dir?" на самом деле ищет какой-либо из пронумерованных флеш-директорий, то есть flash2, flash3 и т. д. Мне удалось передать вывод из файла exp_internal в файл. Есть ли способ опубликовать его здесь, или я должен просто отредактировать свой оригинальный пост и разместить его там? – bjforesthowell
