Linux 中使用脚本启动 Java 服务
Linux 中使用脚本启动 Java 服务
Shell 脚本（优化）
主要除去了不必要的指令，同时使用 dirname、realpath 指令来设置关键变量

将脚本设置为全局快捷命令
-
执行
sudo vim /etc/bashrc有些解决方式是进入 /etx/profile 中进行修改，但是实测后发现不行，暂不清楚是否由其他因素干扰
-
在文件最后编辑。
# 格式：alias [别名]='sh [脚本路径]/[脚本名]' alias chain='sh /home/bin/chain.sh' -
刷新配置文件
source /etc/bashrc -
查看是否已经加入
alias [别名] 或 alias
遇到的问题
-
运行脚本出现：
chain.sh: line 1: $'\r': command not found解决：执行如下指令
sed -i 's/\r//' one-more.sh
