shell脚本通过read实现与键盘交互

#!/bin/bash
 
read -p "输入你想执行的操作(run|kill):" exec
read -p "输入对应的进程(server|web|all):" process

function run_process() {
    case ${1} in
    all)
        echo '启动所有进程'
    ;;
    server)
        echo '只启动server'
    ;;
    web)
        echo '只启动web'
    ;;
    *)
        echo "Usage: $0 {server|web|all}"
    ;;
    esac
}

function kill_process() {
    case ${1} in
    all)
        echo '杀掉所有进程'
    ;;
    server)
        echo '杀掉server的进程'
    ;;
    web)
        echo '杀掉web的进程'
    ;;
    *)
        echo "Usage: $0 {server|web|all}"
    ;;
    esac
}

case $exec in
run)
    run_process $process
;;
kill)
    kill_process $process
;;
*)
    echo "Usage: $0 {run|kill}"
;;
esac

echo '结束'
