- control structures can have redirections (while read l; do ...; done
< file), which apply to all commands in them; they run in the shell
- in pipes and in the background they run in a subshell (cmd | while
read l; do ...; done, for ...; done &, a && b &)
- ( list ) subshells; ( and ) are operators now
- here-documents <<EOF, <<-EOF, <<'EOF' and here-strings <<<word
- redirections of source apply to the commands of the file
- fix non-ASCII characters in quotes being mangled ('für')
