The Bourne shell’s while loop uses exit codes, like the if conditional. For example, this script does 10 iterations: Bourne shell 的 while 循环使用退出代码,就像 if 条件一样。例如,此脚本进行了 10 次迭代: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #!/bin/sh FILE=/tmp/whiletest....
You can break out of a while loop with the break statement. The Bourne shell also has an until loop that works just like while, except that it breaks the loop when it encounters a zero exit code rather than a nonzero exit code. This said, you shouldn’t need to use the while and ...
Shell Scripting - While LoopEASY We will discuss the while loop, its syntax, and boolean operators for conditioning. We will also implement a while loop in a limit and an infinite loop. AuthorAlankrit Srivastava 1 upvote Shell Scripting - Until, Select and For LoopEASY ...
most of the scripts we have written over the years at the Script Center did not use theWhile…Wendloop. That does not mean that it is wrong, nor is one any better
AB, we hope that you will explore theDo…While…Loopconstruction with Windows PowerShell, and you will be able to use it to meet your scripting needs. You know, while I was at the Riverbanks Zoo this weekend, I saw another bear as well. If you encounter a bear while scripting,...

A handy way to iterate through all of the parameters passed involves the use of a while loop and the shift command. This command is what lets you iterate through all the arguments in the argument list (rather than remaining in an infinite loop)....
