As title, for a shell script to accomplish it, it is doable:

test.sh

#/bin/sh
while read line; do
    echo ${line%.xx}
done < input.txt

input file

$ cat input.txt
hello.xx
my.xx

testdriving

$ ./test.sh
hello
my

Use following pattern:

If remove .xx from everywhere

s/\.xx//g

If remove .xx only at the end

s/\.xx$//g
