分裂功能 [英] split function
问题描述
我是perl编程的新手。
我要求验证用户收到的输入文件并将其发送到打印机。
例如：
脚本-o选项-p printername -f文件名
脚本 - 是我的脚本的名称
-o选项 - 是必须用另一个文件验证的选项
-p printername - 是的名称我的打印机
-f filename - 是必须打印的文件名。
在这种情况下如何使用此拆分功能。我想采取 -o选项并将其与文件进行比较。
我已准备好打印队列。什么是将文件名发送到打印机的命令。
请帮助我。
谢谢。
Hi,
I am new to perl programming.
I have a requirement to validate the input received from the user with the file and send it to the printer.
For Eg:
script -o option -p printername -f filename
script - is the name of my script
-o option- is the option that has to be validated with another file
-p printername - is the name of my printer
-f filename - is the filename which has to be printed.
how to use this split function in this case. I want to take" -o option" and compare it with the file.
I already have a print queue ready. what is teh command to send the filename to the printer.
Please help me.
Thanks.

要处理命令行选项，您可以使用 GetOpt :: Std 模块。
To process command line options, you can make use of GetOpt::Std module that comes with default Perl installation.
