如何将“expect”与“zipcloak” II 一起使用？

这个问题是后续问题这个问题，因为我发现我在上一个问题中提出的解决方案不再有效。它有时有效，但现在expect不能按预期工作。这是完整的代码：

#!/bin/bash
MYPWD="mypassword"

expect -c ' 
    spawn zipcloak test.upd
    expect "*Enter password*" 
    sleep 1
    send  "'"$MYPWD"'\r"
    sleep 1
    expect "*Verify password*" 
    sleep 1
    send  "'"$MYPWD"'\r"
    sleep 1
    '

此 bash 脚本不会加密文件test.upd，而是在我的目录中创建以“zi”开头的文件，例如zi0gA1rU或zi8Vv6OD。

这是为什么？那些文件是什么？为什么上面的脚本有时有效，有时无效？难道就没有办法让expect自己的行为举止得体吗？

我在哪里可以找到 的源代码zipcloak，以便我可以重写它以避免使用expect？

附加信息：

  • 我必须以 执行此命令root，因为 zip 文件具有 root 权限。也许这很重要？

当它停止工作后，我需要将最后一个设置sleep为2。然后它又工作了。但后来，这也行不通了。所以我把时间设置sleep为5秒。目前，我的脚本正在运行。但不可靠。

使用 set 调试输出exp_internal 1：

spawn /usr/bin/test.upd
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {28746}

expect: does "" (spawn_id exp6) match glob pattern "*Enter password*"? no
Enter password: 
expect: does "Enter password: " (spawn_id exp6) match glob pattern "*Enter password*"? yes
expect: set expect_out(0,string) "Enter password: "
expect: set expect_out(spawn_id) "exp6"
expect: set expect_out(buffer) "Enter password: "
send: sending "XXX\r" to { exp6 }

expect: does "" (spawn_id exp6) match glob pattern "*Verify password*"? no

Verify password: 
expect: does "\r\nVerify password: " (spawn_id exp6) match glob pattern "*Verify password*"? yes
expect: set expect_out(0,string) "\r\nVerify password: "
expect: set expect_out(spawn_id) "exp6"
expect: set expect_out(buffer) "\r\nVerify password: "
send: sending "XXX\r" to { exp6 }
argv[0] = expect  argv[1] = -c  argv[2] = 
    exp_internal 1
    spawn /usr/bin/zipcloak "test.upd"
    expect "*Enter password*"
    sleep 1
    send  "XXX\r"
    sleep 1
    expect "*Verify password*"
    sleep 1
    send  "XXX\r"
    sleep 1

set argc 0
set argv0 "expect"
set argv ""

更新：Glenn 发布的第二个脚本的输出是：

spawn zipcloak test.upd
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {9956}
Gate keeper glob pattern for 'password: $' is 'password: '. Activating booster.

expect: does "" (spawn_id exp6) match regular expression "password: $"? Gate "password: "? gate=no
Enter password:
expect: does "Enter password: " (spawn_id exp6) match regular expression "password: $"? Gate "password: "? gate=yes re=yes
expect: set expect_out(0,string) "password: "
expect: set expect_out(spawn_id) "exp6"
expect: set expect_out(buffer) "Enter password: "
send: sending "mypassword\r" to { exp6 }
expect: continuing expect

expect: does "" (spawn_id exp6) match regular expression "password: $"? Gate "password: "? gate=no
mypassword

expect: does "mypassword\r\n" (spawn_id exp6) match regular expression "password: $"? Gate "password: "? gate=no
expect: timed out
argv[0] = expect  argv[1] = -c  argv[2] =
    exp_internal 1
    spawn zipcloak test.upd
    expect {
        -re {password: $} {send "mypassword\r"; exp_continue}
        eof
    }

set argc 0
set argv0 "expect"
set argv ""

更新

我实际上想在命令行上指定文件名和密码来调用代码

./myscript.sh test.upd pass

这是脚本：

#!/bin/bash
expect -c " 
    exp_internal 1
    spawn zipcloak \"$1\"
    expect {
        -re {password: \$} {send \"$2\r\"; exp_continue}
        expect eof
    }
"

但是，它会再次创建一个以 开头的文件zi，并且不会加密实际文件。我不知道每一个看似逻辑上的小变化都会破坏expect脚本的整个工作流程。这是输出：

spawn zipcloak test.upd
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {16791}
Gate keeper glob pattern for 'password: $' is 'password: '. Activating booster.

expect: does "" (spawn_id exp6) match regular expression "password: $"? Gate "password: "? gate=no
"expect"? no
Enter password:
expect: does "Enter password: " (spawn_id exp6) match regular expression "password: $"? Gate "password: "? gate=yes re=yes
expect: set expect_out(0,string) "password: "
expect: set expect_out(spawn_id) "exp6"
expect: set expect_out(buffer) "Enter password: "
send: sending "pass\r" to { exp6 }
expect: continuing expect

expect: does "" (spawn_id exp6) match regular expression "password: $"? Gate "password: "? gate=no
"expect"? no
pass

expect: does "pass\r\n" (spawn_id exp6) match regular expression "password: $"? Gate "password: "? gate=no
"expect"? no
expect: timed out
argv[0] = expect  argv[1] = -c  argv[2] =
    exp_internal 1
    spawn zipcloak "test.upd"
    expect {
        -re {password: $} {send "pass\r"; exp_continue}
        expect eof
    }

set argc 0
set argv0 "expect"
set argv ""

我会把 zipcloak-er 写成

#!/usr/bin/env expect
set zipfile [lindex $argv 0]
if {![file exists $zipfile]} {error "no such zipfile: $zipfile"}
set pass "mypassword"
spawn zipcloak $zipfile
expect {
    -re {password: $} {send "$pass\r"; exp_continue}
    eof
}

exp_continue由于“输入密码：”和“验证密码：”提示具有共同的后缀，因此重用代码是有意义的。

“不起作用”没有帮助。你用了吗exp_internal 1？尝试这个：

#!/bin/bash
MYPWD="mypassword"

expect -c " 
    exp_internal 1
    spawn zipcloak test.upd
    expect {
        -re {password: \$} {send \"$MYPWD\\r\"; exp_continue}
        eof
    }
"

抱歉亚历克斯，我不明白你的问题。这就是我在 bash 中发生的情况：

$ zip test.upd file
  adding: file (deflated 22%)
$ MYPWD="mypassword"
$ expect -c " 
    exp_internal 1
    spawn zipcloak test.upd
    expect {
        -re {password: \$} {send \"$MYPWD\\r\"; exp_continue}
        eof
    }
"

spawn zipcloak test.upd
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {27485}
Gate keeper glob pattern for 'password: $' is 'password: '. Activating booster.

expect: does "" (spawn_id exp4) match regular expression "password: $"? Gate "password: "? gate=no
Enter password: 
expect: does "Enter password: " (spawn_id exp4) match regular expression "password: $"? Gate "password: "? gate=yes re=yes
expect: set expect_out(0,string) "password: "
expect: set expect_out(spawn_id) "exp4"
expect: set expect_out(buffer) "Enter password: "
send: sending "mypassword\r" to { exp4 }
expect: continuing expect

expect: does "" (spawn_id exp4) match regular expression "password: $"? Gate "password: "? gate=no

Verify password: 
expect: does "\r\nVerify password: " (spawn_id exp4) match regular expression "password: $"? Gate "password: "? gate=yes re=yes
expect: set expect_out(0,string) "password: "
expect: set expect_out(spawn_id) "exp4"
expect: set expect_out(buffer) "\r\nVerify password: "
send: sending "mypassword\r" to { exp4 }
expect: continuing expect

expect: does "" (spawn_id exp4) match regular expression "password: $"? Gate "password: "? gate=no


expect: does "\r\n" (spawn_id exp4) match regular expression "password: $"? Gate "password: "? gate=no
encrypting: file

expect: does "\r\nencrypting: file\r\n" (spawn_id exp4) match regular expression "password: $"? Gate "password: "? gate=no
expect: read eof
expect: set expect_out(spawn_id) "exp4"
expect: set expect_out(buffer) "\r\nencrypting: file\r\n"
argv[0] = expect  argv[1] = -c  argv[2] =  
    exp_internal 1
    spawn zipcloak test.upd
    expect {
        -re {password: $} {send "mypassword\r"; exp_continue}
        eof
    }
