Just loop through the .log files and move them:

for file in *.log
do
    mv "$file" "${file%.log}"
done

This uses shell parameter expansion:

$ d="a.log.log"
$ echo "${d%.log}"
a.log

Using rename to rename all .log files by removing .log from the end:

rename 's/.log$//' *.log

.log$ matches .log at the end of the file name and it is being omitted by replacing with blank

If you are using prename , then you can do a dry-run first:

rename -n 's/.log$//' *.log

If satisfied with the changes to be made:

rename 's/.log$//' *.log
