增强版重启进程函数:restart-multi-ps
【Cygwin/WSL专用Shell函数,restart-multi-ps(带命令行参数重启某进程)】适配系统存在多个同名进程的情况,可以手动输入序号选择操作哪一个进程;
restart-multi-ps()
# 重启某进程,本函数匹配多个同名进程实例存在的情况
if [ $# -eq 0 ] || [[ "$*,," == "-h" || "$*,," == "--help" ]]; then
echo "restart-multi-ps:带命令行参数重启某进程,例如重启frpc等进程极为有用!"
echo "restart-multi-ps:本函数适配存在多个同名进程的情况,提供手动输入序号选择的选项!"
echo -e "\\n参数说明:"
echo -e "\\$1 —— 必选,进程名称,eg:msedge|msedge.exe"
echo -e "\\$2 —— 可选,指定运行窗口显示方式,显示或隐藏;有效的参数有两个:show/hide,可省略,默认为show"
echo -e "\\$3 —— 可选,start命令运行窗口的Caption标题栏,可省略,默认为空"
echo -e "\\nUsage:restart-multi-ps process-name [windows state(show/hide)] [cmd Caption]"
echo -e "\\nExample:restart-multi-ps frpc.exe"
echo -e "\\t restart-multi-ps frpc"
echo -e "\\t restart-multi-ps frpc.exe Caption:Frpc内网穿透"
echo -e "\\t restart-multi-ps frpc.exe hide 第一个Frpc进程..."
echo -e "\\t restart-multi-ps frpc.exe show 第二个Frpc进程..."
return
fi
local psName="$1"
local windowState="$2"
psInfo=$(wmicps "$psName" --nopath|dos2unix -q|iconv -f GBK -t UTF-8|grep -iE (ProcessId=|ExecutablePath=|CommandLine=)) #注意iconv兼容命令行参数带中文的情况
if [ -z "$psInfo" ]; then
echo "没有找到相关进程..."
return
fi
psCount=0
parsePsInfo()
if [[ "$2" =~ CommandLine\\= ]]; then

echo "提示:按Pid终止单个进程请直接输入序号数字即可,如 12,如果需终止所有同名进程,并按所选的命令行参数重新运行进程,请输入任意字母+数字序号,比如 \\`a12\\`"
read -p "共有 $psCount 个同名实例,你要操作哪一个进程,请选择:" psChoose

##判断窗口隐藏状态,部分Console类窗口视具体情况可能需要隐藏运行,如(mysqld、httpd等),也可以在$2中使用`show`或`hide`显式指定
if [[ "$windowState,," == "show" ]]; then
local runState=" "
shift
elif [[ "$windowState,," == "hide" ]]; then
local runState=" /B "
shift
##针对一些常用的后台进程常驻服务(MySQL、MongoDB等)。不指定窗口显示方式时,默认方式即设为隐藏窗口
elif [ -z "$windowState" ] & & [[ "$psName,," =~ ^mysqld || "$psName,," =~ ^httpd || "$psName,," =~ ^frpc ]]; then
local runState=" /B "
else
local runState=" "
fi
echo "$commandLine"|grep -iE \\\\.*\\.exe"?& > /dev/null
if [ $? -eq 0 ]; then
runCommandLine="$commandLine"
batPrefix="@pushd \\""$(cygpath -aw `dirname "$exePath"`)"\\"" #保险起见:无论如何都pushd到可执行文件所在路径
else
echo "命令行参数需要特殊处理..."
batPrefix="@pushd \\""$(cygpath -aw `dirname "$exePath"`)"\\""
_commandLine=$(echo "$commandLine"|awk -Fgsub($1" ",""); print $0)
