<a href="https://en.wikipedia.org/wiki/Sed" rel="noreferrer">sed</a> cannot match <code>\n</code> because the trailing newline is removed before the line is put into the pattern space, but it can match <code>\r</code>, so you can convert <code>\r\n</code> (DOS) to <code>\n</code> (Unix) by removing \r:
<pre><code>sed -i 's/\r//g' file
</code></pre>
Warning: this will change the original file
However, you cannot change from Unix EOL to DOS or old Mac (<code>\r</code>) by this. More readings here:

Actually, Vim does allow what you're looking for. Enter Vim, and type the following commands:
<pre><code>:args **/*.java
:argdo set ff=unix | update | next
</code></pre>
The first of these commands sets the argument list to every file matching <code>**/*.java</code>, which is all Java files, recursively. The second of these commands does the following to each file in the argument list, in turn:
<ul>
<li>Sets the line-endings to Unix style (you already know this)</li>
<li>Writes the file out <a href="https://en.wiktionary.org/wiki/iff#Conjunction" rel="nofollow noreferrer">iff</a> it's been changed</li>

The tr command can also do this:
<pre><code>tr -d '\15\32' &lt; winfile.txt &gt; unixfile.txt
</code></pre>
and should be available to you.
You'll need to run tr from within a script, since it cannot work with file names. For example, create a file myscript.sh:
<pre><code>#!/bin/bash

for f in `find -iname \*.java`; do
 echo &quot;$f&quot;
 tr -d '\15\32' &lt; &quot;$f&quot; &gt; &quot;$f.tr&quot;
 mv &quot;$f.tr&quot; &quot;$f&quot;
 recode CP1252...UTF-8 &quot;$f&quot;
done
</code></pre>
Running <code>myscript.sh</code> would process all the java files in the current directory and its subdirectories.

I'll take a little exception to <a href="https://stackoverflow.com/questions/3891076/how-to-convert-windows-end-of-line-in-unix-end-of-line-cr-lf-to-lf/19283453#19283453">jichao's answer</a>. You can actually do everything he just talked about fairly easily. Instead of looking for a <code>\n</code>, just look for carriage return at the end of the line.
<pre><code>sed -i 's/\r$//' &quot;${FILE_NAME}&quot;
</code></pre>
To change from Unix back to DOS, simply look for the last character on the line and add a form feed to it. (I'll add <code>-r</code> to make this easier with grep regular expressions.)
<pre><code>sed -ri 's/(.)$/\1\r/' &quot;${FILE_NAME}&quot;
</code></pre>
Theoretically, the file could be changed to Mac style by adding code to the last example that also appends the next line of input to the first line until all lines have been processed. I won't try to make that example here, though.
Warning: <code>-i</code> changes the actual file. If you want a backup to be made, add a string of characters after <code>-i</code>. This will move the existing file to a file with the same name with your characters added to the end.
Update: The Unix to DOS conversion can be simplified and made more efficient by not bothering to look for the last character. This also allows us to not require using -r for it to work:
<pre><code>sed -i 's/$/\r/' &quot;${FILE_NAME}&quot;
</code></pre>

I'm a Java developer and I'm using Ubuntu to develop. The project was created in Windows with Eclipse and it's using the <a href="https://en.wikipedia.org/wiki/Windows-1252" rel="noreferrer">Windows-1252</a> encoding.
To convert to UTF-8 I've used the <a href="https://linux.die.net/man/1/recode" rel="noreferrer">recode</a> program:
<pre><code>find Web -iname \*.java | xargs recode CP1252...UTF-8

This command gives this error:
<pre><code>recode: Web/src/br/cits/projeto/geral/presentation/GravacaoMessageHelper.java failed: Ambiguous output in step `CR-LF..data

I've searched about it and get the solution in <a href="http://fvue.nl/wiki/Bash_and_Windows#Recode:_Ambiguous_output_in_step_.60data..CR-LF.27" rel="noreferrer">Bash and Windows, Recode: Ambiguous output in step `data..CR-LF'</a> and it says:
<blockquote>
Convert line endings from CR/LF to a
single LF: Edit the file with Vim,
give the command <code>:set ff=unix</code> and save
the file. Recode now should run
without errors.
</blockquote>
Nice, but I've many files to remove the CR/LF character from, and I can't open each to do it. Vi doesn't provide any option to command line for Bash operations.
Can sed be used to do this? How?
