我想在bash中使用getopts.用户应该选择自己的选项.
大多数选项都有参数,但有两个选项没有参数.当没有参数的选项位于命令的中间时,它工作正常,但是当它在结尾时它不起作用.

注意 – 前两个参数(服务器和密码)是必需的,而不是getopts的一部分.
#!/bin/bash SERVER=${1} PASSWORD=${2} VERSION=v0 ASKED_REVISION=0 DB=schema_1 PROPERTIES=1 FULL=0 USER= # Usage info show_help() { echo " Usage: Environment DBPassword [-V Version] [-R Revision] [-S Schema] [-P] [-F] [-U Username] -V Version Version to deploy. -R Revision Revision number (0 means the latest revision). -S Schema Schema in the DB to deploy. -P No(!)

Use -H flag for help." exit ;; esac done shift $((OPTIND-1)) #This tells getopts to move on to the next argument. echo "Env=$SERVER" echo "Pass=$PASSWORD" echo "Version=$VERSION" echo "Revision=$ASKED_REVISION" echo "Schema=$DB" echo "External Properties=$PROPERTIES" echo "FULL=$FULL" echo "USER=$USER"
-F和-P不应该得到一个参数.当我运行此命令时,它正常工作(中间的-F):
./deploy_test.sh server1 pass1234 -U 555 -R 55555 -F -V v1.0
当-F或-P在命令的末尾时,
这条线无法正常工作(一切正常,但-F):
./deploy_test.sh server1 pass1234 -U 555 -R 55555 -V v1.0 -F
