Using getopts in bash shell script to get long and short command line options28个答案我想支持短和长选项在bash脚本，所以一个可以：
$ foo -ax --long-key val -b -y SOME FILE NAMES
可能吗？
getopt支持长选项。

这里是一个使用你的参数的例子：
#!/bin/bash
OPTS=`getopt -o axby -l long-key: -- "$@"`
if [ $? != 0 ]
then
exit 1
fi
eval set -- "$OPTS"
while true ; do
case "$1" in
-a) echo "Got a"; shift;;
-b) echo "Got b"; shift;;
-x) echo "Got x"; shift;;
-y) echo "Got y"; shift;;
--long-key) echo "Got long-key,arg: $2"; shift 2;;
--) shift; break;;
esac
done
echo "Args:"
for arg
do
echo $arg
done
输出$ foo -ax –long-key val -b -y某些文件的名称：
Got a Got x Got long-key,arg: val Got b Got y Args: SOME FILE NAMES
