Shell脚本中也算是一门简易的编程语言了,当然循环是不能缺少的。常用到的循环有for循环和while循环。下面就分别介绍一下两种循环的结构。 【for循环】: Shell脚本中的for循环示例: #! /bin/bash ## author:Xiong Xuehao ## Useforinthis script.foriin`seq15`;doecho$idone 脚本中的seq 1 5 表示从1到5...
因此,想要程序无限循环,则使用语句while (( 1 ))...即可 5、shell里面的for循环如下图所示,显然,和C语言的表示方式差不多,不过是单括号变成了双括号而已 6、浮点数的for循环,其实和整数类似,不过是起点,终点,累加值都变为浮点数而已,其中seq每隔0.1产生一个新的数字,占据一行,然后fp依次从中取数 7、shell...
in my case I noticed that when I run “git commit” it will return immediately with “Aborting commit due to empty commit message.” this is something I encountered in the past and was remedied by configuring git to use “emeditor /sp”. I encountered this again recently and /sp did not...
[root@localhost script]# 到此,shell中的四大循环结构就介绍完毕了。
Sometimes, we may need to take action in a shell script when a particular file is created. For example, we may want to synchronize the execution of two scripts using a file. The first script waits for the second script to create the file. When the second script creates the file, it wa...
PowerShell For($i=1;$i-le10;$i++) {Write-Host"Creating User$i"} For 构造使用初始状态、条件和操作。 在前面的示例中,初始状态为$i=1。 条件为$i -le 10。 指定的条件为 true 时,将处理另一个循环。 处理每个循环后,将执行该操作。 在此示例中,操作为$i++,其使$i递增 1。

ForEach($userin$users) {Set-ADUser$user-Department"Marketing"} 在前面的示例中,有一个名为$users的数组,其中包含 Active Directory 域服务 (AD DS) 用户对象。 ForEach 构造会为每个对象处理一次大括号之间的 Windows PowerShell 命令。 处理命令时,$user是包含数组中每个项的变量。 在第一次迭代中...
