Shell Programming and Scripting

as of our requiremnt some x no of files will be created from a third party tool ,out of them one or two files will be empty i.e size is 0. so i want to remove those files which are empty.
naming of the files which are created will be like this

abc_.txt 0 size
abc_1.txt 4000 size
abc_2.txt 3500 size
abc_3.txt 0 size

these files will be created every time in the same folder and the number of files will be some times 4 or some times 10 ,it varies from time to time .my requiment is to remove the files which are created with 0 size

thanks

find . -name "abc_*.txt" -size 0c -exec rm {} \;
