How to find the files of specific file types using shell script

I want to find the specific file types in a particular directory. Once the file type got matched I need to delete the file. As I have used the below codes but it does not work. Could you suggest solution for this?

directory=/var/log/myFiles

if [ -d $directory ]
then
   for file in $directory/*
      do  
       if [ -f $file ]
       then    
         if [$file==*.log.1]
         then
            rm file            
        fi
       fi
      done 
fi

Shorter and faster solution is using find and xargs:

find /var/log/myFiles -type f -name '*.log.1' | xargs rm

Before doing mass deletes like the above, I do a safety check first, like so:

find /var/log/myFiles -type f -name '*.log1' | xargs ls -1

If your files contain spaces or newlines, use NUL-delimited form of the command above:

find /var/log/myFiles -type f -name '*.log.1' -print0 | xargs -0 rm

You don't actually need a script, find + exec could do that:

find /var/log/myFiles -name "*.log.1" -exec echo rm {} \;

Your script fails:

$ ./script.sh
./script.sh: line 11: [/var/log/myFiles/a==*.log.1]: No such file or directory
./script.sh: line 11: [/var/log/myFiles/a.log.1==*.log.1]: No such file or directory

because the if line is completely wrong, it should be something like:

if [[ "$file" == *.log.1 ]]
