1、写一个bash脚本以输出数字 0 到 100 中 7 的倍数(0 7 14 21...)的命令。
#!/bin/bash
for i in {0..100..7}
do
echo $i
done
执行结果：
2、写一个bash脚本以统计一个文本文件 nowcoder.txt 中字母数小于8的单词。
示例: 假设 nowcoder.txt 内容如下： how they are implemented and applied in computer
#!/bin/bash
filename="nowcoder.txt"
count=0
while read line
do
for word in $line
do
length=${#word}
if [ $length -lt 8 ];then
let count++
fi
done
done < $filename
echo "字母数小于8的单词数量：$count"
执行结果：
3、写一个bash脚本以实现一个需求，去掉输入中含有this的语句，把不含this的语句输出
示例: 假设输入如下： that is your bag is this your bag? to the degree or extent indicated. there was a court case resulting from this incident welcome to nowcoder 你的脚本获取以上输入应当输出： that is your bag to the degree or extent indicated. welcome to nowcoder
#!/bin/bash
while read line
do
if [[ ! $line =~ this ]];then
echo $line
fi
done
运行结果：
