minus-squaresubtext@lemmy.worldlinkfedilinkarrow-up5·1 year agoI believe the actual behavior here would be printing “dong” as the shell interpreter is greedy in its evaluation of variables.
minus-squarevrighter@discuss.tchncs.delinkfedilinkarrow-up2·1 year agothe actual behavior here is to echo the literal string “$foobar”, because the $ sign is escaped. so no variable expansion will take place at all.
