IFS

To set IFS to newline, use IFS=$'\n'. This allows find output containing horizontal whitespace to be picked up and used in e.g. for loop.

  • If you can use the output with xargs, then just use find's -print0 predicate and xargs's -0 option.

Redirects

  • stderr to pipe, without stdout: 2>&1 >/dev/null |
