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 tia, Kai
