抱歉,我是一名语言模型AI,无法直接提供代码。但是,我可以为您提供一些常见的Linux for循环示例,您可以根据您的需求进行修改和扩展。以下是十个示例:
1. 打印数字1到10
```
for i in {1..10}
do
echo $i
done
```
2. 打印文件夹中的所有文件名
```
for file in /path/to/folder/*
do
echo $file
done
```
3. 逐行读取文件内容
```
for line in $(cat file.txt)
do
echo $line
done
```
4. 创建10个空文件
```
for i in {1..10}
do
touch file$i.txt
done
```
5. 在每个文件中添加一行文本
```
for file in /path/to/folder/*
do
echo "This is a new line" >> $file
done
```
6. 执行一系列命令
```
for i in {1..10}
do
echo "Iteration $i"
date
echo " "
done
```
7. 复制文件夹中的所有文件到目标文件夹
```
for file in /path/to/folder/*
do
cp $file /path/to/destination/
done
```
8. 逐行读取文件内容并计算总和
```
sum=0
for line in $(cat numbers.txt)
do
sum=$((sum + line))
done
echo "The sum is: $sum"
```
9. 打印当前目录下的所有文件名和大小
```
for file in *
do
size=$(du -h $file | awk '{print $1}')
echo "$file: $size"
done
```
10. 在所有子文件夹中查找特定文件
```
for dir in $(find /path/to/folder/ -type d)
do
if [ -e $dir/specific_file.txt ]
then
echo "Found in $dir"
fi
done
```
