脚本期望太快：在从文件读取的每一行之间添加一个睡眠时间

Question 1

expect所以，这是一个比较老的讨论，但经过过去一两天的思考，并收集了来自这里和其他地方的用户的一些有用提示后，我决定发布我发现的内容。我也在Mac 并非原生 Linux为此，有些事情很古怪。此脚本从以下 bash脚本调用：

expect -d <filename>.expect

如果在文件#!<PATH to expect> -f的第一行实现*.expect和你：

chmod +x <filename>.expect您的文件将起作用。这-d是附加调试信息。

在您的 bash 脚本中调用expect： expect -df <filename>.expect来实现相同的效果，并且您不需要对文件的可执行权限。

调试信息是非常有助于查看您的expect语句、变量等，如下所示：

spawn <program> <args>
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {29747}

expect: does "" (spawn_id exp10) match glob pattern "Please enter 
passphrase:"? no
Please enter passphrase:
expect: does "Please enter passphrase: " (spawn_id exp10) match glob 
pattern "Please enter passphrase:"? yes
expect: set expect_out(0,string) "Please enter passphrase:"
expect: set expect_out(spawn_id) "exp10"
expect: set expect_out(buffer) "Please enter passphrase:"

这是简短的 bash 脚本，（仅作为示例，但如果您需要它来执行更复杂的事情或只是出于bash某种原因调用它，它会很有帮助）

#!/bin/bash

expect -d exp.expect "$WORD"
RET=$?

if [ $RET -eq 1 ]; then
    #mac specific, sheer laziness, allows me to do other stuff...
    #use esay or similar on Linux
    say "Query was found, expect returned success" 
    echo *************************************************** 
    echo ******************FOUND!***************************
fi
exit 0

脚本如下expect：

#!/usr/bin/expect -f
#capture logs for debugging
log_file -a log_file.txt

#dont timeout, let the program run its course, (was mandatory for me)
set timeout -1;

#capture all of our output for debugging
set output [ open "output.txt" "RDWR" ];

#This procedure is called repeatedly with the next word
proc check_word {w} {

#kickoff our other program we are going to talk to
spawn <program> <args>

#we want this one to go regardless, the next 2 are mutex
expect "Please enter passphrase:" { send "$w\r"; send_user "\nSENDING: $w\r"; send_user "\nOutput BUFFER: $expect_out(buffer)\n" }

#These are mutually exclusive, either worked or not, can be grouped
expect {
"scrypt: Passphrase is incorrect" { send_user "\n*FAILED*\n"; close }
-re {anders} { send_user "$expect_out(buffer)\n"; close; exit 1 }
}
#wait for the process to end, timeout is set to never expire
wait
}

#open the file to take the words from, (happens before proc above)
set input [ open "words.txt" "RDONLY" ];

#while there are still words, (we exit on a match) ...keep going....
while {[gets $input word] != -1} {
        check_word $word;
}
#close input file, TODO do this upon success in expect call too?
close $input
close $words

#EOF

希望这可以帮助一些人/任何人节省一些时间！
