Use shell to convert case sensitivity in linux

In linux, use shell to convert the case-Linux general technology-Linux programming and kernel information. The following is a detailed description. The problem is as follows:

After installing apache, I threw a bunch of web pages into the corresponding folder. You can use the home page if you find that the source file name of the webpage is *. HTM, and the link between webpages is *. htm. I'm dizzy...

There are two solutions. apache redirection will point to *. HTM. I have never done this. So it is like changing the *. HTM file name to *. htm in a speculative way.

The Code is as follows:

1 for file in *. HTM
2 do
3 newfile = 'echo $ file | tr A-Z a-Z'
4 mv $ file $ newfile
5 done

The script language is too concise. Like

Row 3 traverses the current directory to find the qualified. HTM file. The key lies in the 1st sentence. Save the new file name. tr should be used well. I am also from baidu ...... Note that ''is executed and assigned to newfile. 4th rows, rename. Everything is done.
