I would use basename for this.

$ basename --suffix ".gz" example.123.ytu.tar.gz
example.123.ytu.tar

You can find out more about it via man basename

echo example.123.ytu.tar.gz | cut -d "." -f1-4
example.123.ytu.tar

The -f option takes any comma separated list of fields and/or field ranges (with '-'). Eg 

echo example.123.ytu.tar.gz | cut -d "." -f1,2,3,4
example.123.ytu.tar

gives the same output.

Sorry, I was not clear in my question. The exact thing I want is to have a string till *.tar or before ".gz"
I have edited the answer. But if you look at the previous example you should see how to get the result you wanted.

You could simply use grep

echo example.123.ytu.tar | grep -Eo '.*tar'

output: example.123.ytu.tar

The -E option enables extended regular expression mode and the -o option makes grep print only the part of the word that matched the regex.
