如何在 linux 中使用 for 循环创建脚本，以不同方式编辑文件

Question

I have 10 files and I need a script that can, for example, write numbers from 1 to 10 in each file so that in one file would be written one number. I tried doing like this, but it doesn't work:

    #!/bin/bash
    
    for (( i=1; i<=10; i++ )); do
    cat file$i
    $i
    done

Answer 1

Do you mean each file, say 1.txt , contains 1 in it? Then this may work:

 #!/bin/bash
    
for i in {1..10}; do
     echo $i > ${i}.txt
done
