Is there a do-while loop in bash? -

-
this question has answer here: emulating do-while loop in bash 3 answers is there do - while loop in bash? i know how program while loop in bash: while [[ condition ]]; body done is there similar construct, do - while loop, body executed @ least once irrespective of while condition? while loops flexible enough serve do-while loops: while body condition true; done for example, ask input , loop until it's integer, can use: while echo "enter number: " read n [[ -z $n || $n == *[^0-9]* ]] true; done this better normal do-while loops, because can have commands executed after first iteration: replace true echo "please enter valid number" .
