1363 // for example, if $x has the value timelimit, ${$x} will return
1364 // the value of $timelimit
1365 // - when expanding an alias, the special variable name $* refers
1366 // to all alias parameters, and a number refers to that numbered
1367 // alias parameter, where the name of the alias is $0, the first
1368 // parameter is $1 and so on; as a special case, $* inserts all

1370 // pass all parameters around. All parameters starting from $n

1376 // dollar signs have no unwanted bad side effects. However, this needs to

1378 // alias foo "set x NEW; echo $x"

1382 // alias foo "set x NEW; foo2"
1383 // alias foo2 "echo $x"
1385 // Also note: lines starting with alias are exempt from cvar expansion.
1386 // If you want cvar expansion, write "alias" instead:
1389 // alias foo "echo $x"
1390 // "alias" bar "echo $x"
1393 // foo will print 2, because the variable $x will be expanded when the alias
1394 // gets expanded. bar will print 1, because the variable $x was expanded
