除了列表,我们还可以利用for-in循环遍历文件中的内容。例如,如果我们有一个包含文件名的文本文件,我们可以使用for-in循环逐行读取文件中的数据。示例代码如下: ``` filename="files.txt" for file in $(cat $filename) do echo "Processing file: $file" # 进行其他操作... done ``` 上述代码将会逐行读取...
for i in `ls` # 错误! for i in $(find . -type f) # 错误! for i in `find . -type f` # 错误! files=($(find . -type f)) # 错误! for i in ${files[@]} # 错误! 这里主要两个问题: 使用命令展开时不带引号,其执行结果会使用 IFS 作为分隔符,拆分成参数传递给 for 循环处理;...

The rendered files will be created in the same directory, and have .template replaced with .rendered. The rendered file will be symlinked into the home directory with the .rendered suffix removed and a pre-prended dot. For example: If you have the file default/env.template with the below...
The rm command is short for "remove." As you'd expect, rm deletes files. So this command puts an end to 0001.jpg:Bash Copy rm 0001.jpg And this command deletes all the files in the current directory:Bash Copy rm * Be wary of rm. It's a dangerous command....
system, and in this case, the Bash shell. To get help with a specific command, you can use themancommand followed by the name of the command you need help with. For example,man lswill provide information on the ls command, which is used for listing directories and finding files. ...

这个写法的另一个常见用途,是直接用于for循环。 for i in {1..4}do echo $idone 上面例子会循环4次。 如果整数前面有前导0,扩展输出的每一项都有前导0。 $ echo {01..5} 01 02 03 04 05 $ echo {001..5} 001 002 003 004 005 这种简写形式还可以使用第二个双点号(start..end..step),用来...
