Replace \n with <br /> in bash

Question

[UPDATED QUESTION]

I've got a variable $CHANGED which stores the output of a subversion command like this: CHANGED="$(svnlook changed -r $REV $REPOS)".

Executing svnlook changed -r $REV $REPOS will output the following to the command line:

A /path/to/file
A /path/to/file2
A /path/to/file3

However, I need to store the output formatted as shown below in a variable $FILES:

A /path/to/file<br />A /path/to/file2<br />A /path/to/file3<br />

I need this for using $FILES in a command which generates an email massage like this:

sendemail [some-options] $FILES

应该替换为$FILES，A /path/to/file<br />A /path/to/file2<br />A /path/to/file3<br />以便它可以解释html break标签。

Answer 1

在bash中：

echo "${VAR//$'\n'/<br />}"
