1255 // to all alias parameters, and a number refers to that numbered

1257 // parameter is $1 and so on; as a special case, $* inserts all

1259 // pass all parameters around. All parameters starting from $n

1265 // dollar signs have no unwanted bad side effects. However, this needs to

1271 // alias foo "set x NEW; foo2"
1272 // alias foo2 "echo $x"
1274 // Also note: lines starting with alias are exempt from cvar expansion.
1275 // If you want cvar expansion, write "alias" instead:
1278 // alias foo "echo $x"
1279 // "alias" bar "echo $x"
1282 // foo will print 2, because the variable $x will be expanded when the alias
