Code:
echo "abc.xyz" | awk -F. '{print $1}'
abc

Code:
echo ${1%.*}

where $1 is the first argument passed to the script. If you are storing the argument in a variable, you can use

Code:
echo ${FILENAME%.*}

where FILENAME is the variable which stores the argument passed.

Replace name= "$fullname" | cut -f1 -d"." with

Code:
name=$(echo "$fullname" | cut -f1 -d".")

There is a simpler way
If you always know the extension and if it static..says extension is always xyz then you can use 'basename'

>basename abc.xyz .xyz
abc
