等待多个流程完成预期

Question

我正在寻找一个期望从多个工作中观察输出的构造，并且直到所有工作都返回预期输出或超时时才完成。

Answer 1

了解间接产卵ID。这现在有效。

#!/usr/bin/env expect

spawn echo 0 Passed
set list $spawn_id

spawn echo 1 Passed
set list "$list $spawn_id"
set waiting_cnt [llength $list]

send_user "list is '$list', length $waiting_cnt\n"

set timeout 2

expect {
    -i list eof {
        set index [lsearch $list $expect_out(spawn_id)]
        set list  [lreplace $list $index $index]
        if [llength $list] exp_continue
    }

    -i list -re Passed {
        send_user "passed seen on $expect_out(spawn_id)\n"
        incr waiting_cnt -1
        exp_continue
    }
}

send_user "both seem to have passed, waiting_cnt = $waiting_cnt\n"
