運行腳本時輸出不返回任何內容

Question

當我運行此腳本時，我什么也沒有返回。 有什么建議么？ 這是代碼。

securityTlsVersion() {
     local file="/usr/lib/firefox/mozilla.cfg"
     local config=`more $file|grep security.tls.version.max`
     local tlsmax="lockPref(\"security.tls.version.max`
     if [ "`hostname`" == "server1" ] || [ "`hostname`" == "server2" ];then
       if [ "$config" = "" ]; then
         echo "Adding security.tls.version.max line to mozilla.cfg"
         echo "tlsmax >> $file
         echo "security.tls.version.max is now configured"
       else
         echo "security.tls.version.max is already configured"
       fi
     fi
 }

下面是shellcheck的結果。 這意味着第一行包含未關閉的" 。正如@JNevill所寫，這是從local tlsmax開頭的行：

shellcheck myscript.sh 

In myscript.sh line 7:
     if [ "`hostname`" == "server1" ] || [ "`hostname`" == "server2" ];then
        ^-- SC1009: The mentioned parser error was in this test expression.
          ^-- SC1073: Couldn't parse this double quoted string.
           ^-- SC1072: Expected end of double quoted string. Fix any mentioned problems and try again.

有幫助嗎？
