Shell,执行一个需要逐一遍历多个值的命令

steam variables shell bash

Plankt0n · 技术社区 · 1 年前

我有一个脚本:

if [ $ModEnabled == "1" ];then
    ${HOME}/servers/steamcmd/steamcmd.sh +force_install_dir ${HOME}/servers/dayzserver/ +login "${SteamUser}"  +workshop_download_item 221100 1559212036 validate +quit
    printf "Done"
else
    echo "Variable is not set"
fi

但是,我需要做的是运行该命令 +workshop_download_item 221100 1559212036 validate

当它重新运行/循环该命令时,将特定值“1559212036”替换为多个值的列表。

愿景是:(假代码,显然哈哈)

modlist={"
    123123123,
    234456567,
    456456456,
    567567567,"
}

那么这将运行:

${HOME}/servers/steamcmd/steamcmd.sh +force_install_dir ${HOME}/servers/dayzserver/ +login "${SteamUser}"  +workshop_download_item 221100 $modlist, then run again with the next item in modlist" validate +quit

如果可以在不每次调用“+quit”的情况下做到这一点,那将是一个额外的好处(但我想这是steamcmd的事情。

你可以这样做:

for mod in 123123123 234456567 456456456 567567567
do
   ${HOME}/servers/steamcmd/steamcmd.sh \
      +force_install_dir ${HOME}/servers/dayzserver/ \
      +login "${SteamUser}"  \
      +workshop_download_item 221100 $mod \
      validate +quit
done

在这种情况下 $mod 变量将在关键字后定义值 in 逐一地。

您要查找的构造是 for loop .

DayZModList="
123123
456456
789789
"

if [ $ModEnabled == "1" ];then
    for value in $DayZModList ; do
        ${HOME}/servers/steamcmd/steamcmd.sh \
        +force_install_dir ${HOME}/servers/dayzserver/ \
        +login "${SteamUser}" \
        +workshop_download_item 221100 "${value}" \
        validate +quit
    done

    printf "Done"
else
    echo "Variable is not set"
fi

您设置了迭代器(我使用了变量名 value ,但你可以使用任何你喜欢的东西),然后使用(在这个例子中)访问它 "${value}" .

好吧,我很快就聊过了。这是以下代码:

#Configure if using mods. 
ModEnabled="1" # If 1 = Install/update mods 
DayZModList=("1559212036" "1828439124" "2545327648"

#Update Mods
if [ $ModEnabled == "1" ];then
    printf "[ ${yellow}REALM-SERVER${default} ] Updating/Downloading Mod files!\n"
    for value in ${DayZModList[@]}; do
        ${HOME}/servers/steamcmd/steamcmd.sh +force_install_dir ${HOME}/servers/dayzserver/ +login "${SteamUser}"  +workshop_download_item 221100 "${DayZModList}" validate +quit
        printf "[ ${green}REALM-SERVER${default} ] Done downloading and updating Mod files!\n"
    done
else
    printf "[ ${red}Error${default} ] You have not enabled downloading and updating mods, skipping!\n"
fi

然而,它跳过了“1559212036”之后的所有内容,实际上并没有下载它们。
