学完python后需要学以致用，但平时还真没有这个环境，也不搞自动化，但语言这玩意必需要用，就拿secureCRT来练手吧，也算是和工作擦点边

对话框加按扭

CONFIRM_REPLACE = """\ #为数不多的button判断

Do you want to replace the contents of "%(FILE)s" with the selected text?

Yes = overwrite

No = append

Cancel = end script"""

message = CONFIRM_REPLACE % { 'FILE' : "filename" }

prompt = "Replace contents"

buttons = BUTTON_YESNOCANCEL

result = crt.Dialog.MessageBox(message, prompt, buttons)

if result == IDYES:

fileMode = "w"

elif result == IDNO:

fileMode = "a"

crt.Dialog.Prompt( #超级有用的在用户这获取数据的方式

"Save selected text to File:",

"SecureCRT - Save selected text to file",

"MyFile.txt")

获取log文件名在SecureCRT

tab = crt.GetScriptTab()

tab.Session.LogFileName

#如果在CRT中设置了log文件名，这个函数可以把它读取出来

#可以直接取到log的文件名 获取系统当前的前缀名

SCRIPT_TAB = crt.GetScriptTab()

rowIndex = SCRIPT_TAB.Screen.CurrentRow

colIndex = SCRIPT_TAB.Screen.CurrentColumn - 1

prompt = SCRIPT_TAB.Screen.Get(rowIndex, 0, rowIndex, colIndex)

#获取当前行，当前列的数据，即该服务器的前缀，与waitfor配套

prompt = prompt.strip()

获取打印值

def CaptureOutputOfCommand(command, prompt):

if not crt.Session.Connected:

return "[ERROR: Not Connected.]"

# First, send the command to the remote.

SCRIPT_TAB.Screen.Send(command + '\r')

#输入命令 cmmand 然后回车

# Second, wait for the carriage return to be echoed by the remote device.

# This allows us to capture only the output of the command, not the line

# on which the command was issued (which would include the prompt + cmd).

# If you want to capture the command that was issued, simply comment out

# the following line of code.

SCRIPT_TAB.Screen.WaitForString('\r'

#等待命令输完后，服务器给的回应，这样可以不是获取行，而是获取输出

# Now that the command has been sent, use Screen.ReadString to capture

# all the data that is received up to the point at which the shell

# prompt appears (the captured data does not include the shell prompt).

return SCRIPT_TAB.Screen.ReadString(prompt)

#获取直到prompt出现时的所有数据

屏幕取词

filename = os.path.join(os.path.expanduser('~'), 'output.txt') #~/output.txt

fp = open(filename, "wb+")

screenrow = crt.Screen.CurrentRow - 1

readline = crt.Screen.Get(screenrow, 1, screenrow, 20)

#把当前行的1~20个字符取出来

fp.write(readline + os.linesep)

#把取出的那一行加行尾符写到文件中

写到excel

import os

import csv #excel module

fileobj = open(filename, 'wb')

worksheet = csv.writer(fileobj)

worksheet.writerow(items[:2])

fileobj.close(

连接

SSH:

cmd = "/SSH2 /L %s /PASSWORD %s /C 3DES /M MD5 %s" % (user, passwd, host)

crt.Session.Connect(cmd) #ssh -L user password host

Telnet:

crt.Session.Connect("/TELNET 127.0.0.1 2034") # telnet 127.0.0.1:2034

crt.Session.Connect("/S \"" + session + "\"")

#如果这个session在CRT里存在，无论是Telnet还是SSH都能连

调试工具 CRT中的print

crt.Dialog.MessageBox("Nothing to save!")
