tr(1) or sed(1) should do

  pitchl@srdscs05:~$ echo "foo fooo foooo fooooo" | tr '[:blank:]' '_'
  foo_fooo_foooo__fooooo

  pitchl@srdscs05:~$ echo "foo fooo foooo fooooo" | tr -d '[:blank:]'
  foofooofoooofooooo

  pitchl@srdscs05:~$ echo "foo fooo foooo fooooo" \
                     | sed 's/[[:blank:]]/_/g'
  foo_fooo_foooo__fooooo

  pitchl@srdscs05:~$ echo "foo fooo foooo fooooo" \
                     | sed 's/[[:blank:]]//g'
  foofooofoooofooooo
