1.1 认识 for ... do ... done 昨天刚学过while,until的循环方式 -->Linux 之 shell script -- loop(不定循环) :符合循环条件便可以无限得循环执行指定的“程序段”,我们便称为不定循环。今天学习与不定循环相对应的for循环,这种语法则是已经知道要进行几次循环的状态。 for ... do ... done的语法结...

echo "$var--->$sum" done a=1 while [ "$a" -le 5 ]; do echo "loop num : $a" a=$(($a+1)) done a1=1 until [ "$a1" -gt 5 ] do echo "until a1:$a1" a1=$(($a1+1)) done s=0 for ((i=1;i<=100;i++)) do s=$(($s...
echo "I am good at ${skill}Script" done 如果不给skill变量加花括号,写成echo "I am good at $skillScript",解释器就会把$skillScript当成一个变量(其值为空),代码执行结果就不是我们期望的样子了。 推荐给所有变量加上花括号,这是个好的编程习惯。
Now for the next script block. First, import the CSV file by passing the content path to theImport-CSVcmdlet. Then, using theforeach()method, loop through the names and create the new users in Active Directory. # Import list of Firstname and Lastname from CSV file$newUsers=Import-Csv-...
(转) 一个从fedora7中拷贝过来的bash脚本,居然不能在ubuntu下面执行,提示错误 Bad for loop variable G了一把,在TW同胞那里找到了答案～原来是bash和dash的问题 解决方法: 使用 sudo dpkg-reconfigure dash 选择NO。。 世界又清静了~(经典!) 感谢link:http://hi.baidu.com/yk103/blog/item/1e9831fa3fc23d...
While 构造运行脚本块,直到指定条件为 false。 虽然它类似于 Do..While 构造,但它不能保证脚本块的运行。 While 构造使用以下语法: PowerShell While($answer-eq"go") {Write-Host"Script block to process"} 下一单元: 查看 Windows PowerShell 脚本中的 Break 和 Continue 下一步...
