for i in {1..9};do for j in `seq $i`;do echo -en "$i*$j=$(($i*$j))\t" done echo done 1. 2. 3. 4. 5. 6. 8、在/testdir目录下创建10个html文件,文件名格式为数字N(从1到10)加随机8个字母,如:1AbCdeFgH.html for i in {1..10};do NUM=`openssl
for i in 1 2 3 4; do echo $i; done 2、测试for的自增长的循环: #!/bin/bash for ((i=1; i<=5; i++)) do echo $i; done 如果会报错,没有则跳过: Syntax error: Bad for loop variable 原因:代码对于标准bash而言没有错,因为Ubuntu为了加快开机速度,用dash代替了传统的bash,是dash在捣鬼。

/bin/bash,好像它还是默认去找了ash,真是让人无奈。上网搜索了一下,找到两种解决方案:1、修改脚本 2、修改系统默认执行shell的工具 第一种的具体做法就是,原来的for循环类似这种 for(( i=1; i<3; i++)),改成类似这种的:for i in `seq 1000`,这是从一个网友的博客上抄来的,我不知道是否等价。但是...
