Pattern match does not work in bash script
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Using the pattern match !("file1") does not work within a bash script but will work on the command line.
For example:
ls !("file1"|"file2")
This will list all files in directory except file1 and file2.
When that line is executed in a script this error is displayed:
./script.sh: line 1: syntax error near unexpected token `('
./script.sh: line 1: ` ls !("file1"|"file2") '
Regardless what is used rm -v !("file1"). The same error takes place. What is going on here why does this not work in a script?

The extended glob syntax you are trying to use is turned off by default; you have to enable it separately in each script where you want to use it.
shopt -s extglob
Scripts should not use ls though I imagine you were using it merely as a placeholder here.

Globbing doesn't work that way unless you enable extglob shell opt. Instead, I recommend using find:
find . -maxdepth 1 -not -name '<NAME>' -or -name '<NAME>' -delete
before running this command with -delete ensure the output is correct
