I want subtract a number in expect shell
until it equals 0, then close this shell, such as :
#!/usr/bin/expect
set round [lindex $argv 0];
incr round -1
if round <= 0 close // ??how to write this sentence?
CodePudding user response:
Your last line would be:
if {$round <= 0} exit
BUT I think you actually want to decrement the counter repeatedly, for which you would need a loop:
while {$round > 0} {
incr round -1
}
