I've a file with a list of files in different directories and want to find the oldest one. It feels like something that should be easy with some shell scripting but I don't know how to approach this. I'm sure it's really easy in perl and other scripting languages but I'd really like to know if I've missed some obvious bash solution.
Example of the contents of the source file:
/home/user2/file1
/home/user14/tmp/file3
/home/user9/documents/file9
