====== Mount_an_ISO_(CD_Image)_on_linux ======

 mount -o loop -t iso9660 /path/to/image.iso /mnt/

===== Problem - ISO-13346 "UDF" file system =====
I recently got the following error when I tried the above:
 server:/mnt# ls -la
 total 5
 dr-xr-xr-x  1 root root  112 Aug 31  2009 .
 drwxr-xr-x 22 root root 4096 Mar 28  2009 ..
 -r-xr-xr-x  1 root root  135 Aug 31  2009 readme.txt
 server:/mnt# cat readme.txt
 This disc contains a "UDF" file system and requires an operating system
 that supports the ISO-13346 "UDF" file system specification.
This was a Windows 7 DVD I wanted to check would mount ok. 

==== Solution ====
 mount -o loop -t udf,iso9660 /path/to/image.iso /mnt/
