Getopt ::长时间将带空格的字符串放入变量 [英] Getopt::Long getting a string with spaces into a variable

问题描述

我正在制作一个使用Getopt :: Long解析命令行参数的perl脚本.但是，我有一个参数可以接受字符串(带空格).我怎样才能把整个字符串变成一个变量.例如:

I'm making a perl script which uses Getopt::Long to parse command line arguments. However, I have an argument which can accept a string (with spaces). How can I get the whole string into a variable. For example:

./script.pl --string=blah blah blah blah yup --another-opt

我需要变量$ string中的等等等等".我知道Getopt :: Long支持一个参数的多个输入，当您知道有多少个时(我不知道).这可能吗?

I need "blah blah blah blah yup" in variable $string. I know Getopt::Long supports multiple inputs for one argument when you know how many you will have (which I do not). Is this possible?

推荐答案

您需要在参数周围加上引号:

You need to either put quotes around the argument:

./script.pl --string="blah blah blah blah yup" --another-opt

或逃脱空格:

./script.pl --string=blah\ blah\ blah\ blah\ yup --another-opt
