This really belongs to the new help-b...@gnu.org mailing list * https://lists.gnu.org/mailman/listinfo/help-bash The most simple is to redirect the output to standard error or the terminal: echo ===="$@" >&2 # not that using set -x will give you this for free echo ===="$@" > /dev/tty Another possibilty is to pass the file name as an argument instead file=$1 shitf echo ===="$@" exec > "$file" "$@"
