如何将getopt与这几个值一起使用? [英] How to use getopt with this several values?

问题描述

我尝试实现具有多个选项的脚本.我从 doc 开始，出现了一些错误，然后转到了浏览器.阅读一些链接并在SO上找到它:

I try to achieve a script with multi options. I started with the doc, get some errors, went to the browser. Read some links and find this on SO : Using getopts in bash shell script to get long and short command line options.

因此，我阅读并重写了我的脚本.我在某个地方犯了一个错误.我在哪里错了?

So I read it and rewrote my script. I made a mistake somewhere. Where am I wrong ?

SH

#!/bin/sh

TEMP=`getopt -o vfts: --long verbose,format,type,style: \
             -n 'opt2' -- "$@"`

if [ $? != 0 ] ; then echo "Terminating..." >&2 ; exit 1 ; fi

eval set -- "$TEMP"

VERBOSE=false
FORMAT=
TYPE=
STYLE=
while true; do
    case "$1" in
        -v | --verbose ) VERBOSE=true; shift ;;
        -f | --format ) FORMAT="$2"; shift 2 ;;
        -t | --type ) TYPE="$2"; shift 2 ;;
        -s | --style ) STYLE="$2"; shift 2 ;;
        -- ) shift; break ;;
        -*) break ;;
        * ) break ;;
    esac
done

echo "verbose = $VERBOSE"
echo "format = $FORMAT"
echo "type = $TYPE"
echo "style = $STYLE"

输出

> ./opt2.sh -v -f fofo -t toto -s soso

verbose = true // ok
format = -t // should be fofo
type =  // should be toto
style = soso // ok

推荐答案

您的选项字符串错误，应为 vf:t:s:.冒号表示必需的参数，除了v之外，每个选项都有.还需要相应地调整长选项字符串.

Your options string is wrong, it should be vf:t:s:. The colon indicates a required argument which each of your options except for v has. Also need to adjust your long options string accordingly.
