====== Mass renaming in bash ======

Add prefix to filename:
<code>rename 's/^/MyPrefix_/' *</code>

Remove part of filename:
<code>rename 's/SEARCH/REPLACE/' *</code>

Add suffix to filename:
<code>rename 's/$/_MySuffix/' *</code>

Rename extension:
<code>rename 's/\.pdf$/.doc/' *</code>

Swapping parts of filename:
<code>rename 's/(.*) - Linkin Park (.*)$/Linkin Park - $1 $2/' *.mkv</code>

for dry-run, use -n option!

Mass moving files from numbered directories into another one (bash for loop):
<code>for i in `seq 2 30`;do mv bla$i/* target_directory ; done</code>



A graphical bulk renaming tool is:
<code>sudo apt-get install pyrenamer</code>
