Yes. Check this ls capturing for hiding some file (grep -v filters
pattern):

[rodolfoap] /home/rodolfoap/test > ls

test_one  test_three  test_two

[rodolfoap] /home/rodolfoap/test > function ls() { /bin/ls|grep -v two; }

[rodolfoap] /home/rodolfoap/test > ls

test_one

test_three

[rodolfoap] /home/rodolfoap/test >

The value of a program is inversely proportional to the weight of its
output.
