Shell script syntax warning about missing quote

Question

I'm a new beginner of shell scripting. I cannot figure out why the following script keep pop up warning that there are some missing 「"」? Can someone help me take a look?

  if [ $portalweb_prepared == "true"];then
    CHECK="false";
  elif [ $ims_prepared == "true"] &&[ $same_version == "false" ];then
    CHECK="false";
  elif [ $portalapi_prepared == "true"] &&[ $same_version == "false" ];then
    CHECK="false";
  fi

This should be written as follows:

if [ "$portalweb_prepared" = "true" ]
then
    CHECK="false"
elif [ "$ims_prepared" = "true" ] && [ "$same_version" = "false" ]
then
    CHECK="false"
elif [ "$portalapi_prepared" = "true" ] && [ "$same_version" = "false" ]
then
    CHECK="false"
fi

Very similar, but almost all the spaces are significant, and the rest aid readability.

I think the spaces around the double ampersands are not significant. – ceving Jul 03 '17 at 14:18
What is really important are the spaces around the `[` and `]` in IFs statements! And I agree with spaces around &&. – linuxfan says Reinstate Monica Jul 03 '17 at 14:54
It's truly works!!! So, the space really affects in shell script syntax? – user2933783 Jul 04 '17 at 02:54
Yeah, Bash is a weird language like that. – l0b0 Jul 04 '17 at 13:30
