What do backquotes do?
What exactly do backquotes do? I've seen the uname example in the
manual, but that leaves a number of questions open.
For example, can I only use backquotes for the value? Or can I also use
it for the name?
| set foo=`echo bar`
This is a somewhat silly way to set the variable foo to the value bar.
But will the following line do the same?
| set `echo foo`=bar
And what about this?
| `echo set` foo=bar
And what if the shell command prints more than one line?
| `echo foo; echo bar`
Will the above do the same as the following two lines?
| foo
| bar
