[Li|Nux]: braces on the command line
Self-tutoring about Linux: the tutor mentions braces.
On the system I use,
{ Enter
will open up a subshell into which you can enter one command per line, as if in a script file. On the last line I just do} Enter
which closes the subshell. Then, the commands entered will execute.
