^M in vi with php files
Why do I see ^M in vi with php files? I don't see that in any other type of files.

I added this to my .bashrc and it went away. Does anyone know why this is happening? What does exporting xterm-color do that makes it go away?
Code:
export TERM="xterm-color"

Did you ever edit them in Notepad? That will fill them with carriage returns because Windows uses \r\n while UNIX uses \n

For PHP files or webpages it may not make an enormous difference. For other script files it can be an annoying problem.

I didn't. Someone else may have. I am learning me way around a new server right now. Trying to understand all of the shellscripts and php files.

In vi you can do
Code:
:%s/<C-V><C-M>//g

where C-V and C-M are keys you should press on keyboard.

This is happening because the file is imported from a Windows file system. Issue the command:
Code:
dos2unix filename.php

..to change the file to unix format.

...except nobody actually has dos2unix, so sed -i 's/\r//' filename will work better (on linux. on other systems you may need to tr -d '\r' < filename > tempname ; cat tempname > filename ; rm tempname )

What does this do? Does C-V mean ctrl V?

I don't have dos2inix but it is in my repository?

What do those sed and tr commands do? I like to learn Smilie.
