[英]Getopts in bash script with sub-arguments
我希望能够运行这样的脚本(带有子参数):我需要能够使用短选项和长选项
./myscript.sh -u myname --delete-config --delete-data
./myscript.sh -a myname..........................
./myscript.sh -h
其实我有:
OPTS=`getopt -o a?d:h?dd?dc? --long apps,delete:,delete-data,delete-config -n 'parse-options' -- "$@"`
if [ $? != 0 ] ; then echo "Failed parsing options." >&2 ; exit 1 ; fi
eval set -- "$OPTS"
while true; do
case "$1" in
-a | --apps )
showHelp
exit 0
;;
-d | --delete )
username="$2"
echo $username
shift 2
echo "$1"
echo "$2"
# Here i can add argument to the command
case "$1" in
-dd | --delete-data )
deleteData
shift 1
;;
-dc | --delete-config )
deleteConfig
shift 1
;;
* ) echo "Unexpected option: $1 - this should not happen."
showHelp
break
;;
esac
;;
-h | --help )
showHelp
break
;;
-- ) shift;
break
;;
* ) echo "Unexpected option: $1 - this should not happen."
showHelp
break
;;
esac
done
脚本的结果是:
--delete toto --delete-data --delete-config
多多
--删除数据
--删除配置
压制过程中的数据
意外选项:--delete-config - 这不应该发生。
我不明白我在 shift 和 getopts 上做错了什么
版本略有不同:
#!/usr/bin/env bash
OPTS=`getopt -o a?d:h?dd?dc? --long apps,delete:,delete-data,delete-config -n 'parse-options' -- "$@"`
if [ $? != 0 ] ; then echo "Failed parsing options." >&2 ; exit 1 ; fi
eval set -- "$OPTS"
while test "$1" != --; do
case "$1" in
-a | --apps )
showHelp
exit 0
;;
-d | --delete )
username="$2"
echo $username
shift 2
echo "$1"
echo "$2"
# Here i can add argument to the command
while test "$1" != --; do
case "$1" in
-dd | --delete-data )
echo deleteData
shift 1
;;
-dc | --delete-config )
echo deleteConfig
shift 1
;;
* ) echo "Unexpected option: $1 - this should not happen."
showHelp
break
;;
esac
done
;;
-h | --help )
showHelp
break
;;
-- ) shift;
break
;;
* ) echo "Unexpected option: $1 - this should not happen."
showHelp
break
;;
esac
done
无效的解决方案,它只在这种情况下有效,不适用于 3 个子参数
感谢 Philippe 的评论:如果您认为这不好,或者目的更好并确认为答案,请告诉我:)
