Unix equivalent of dir/s ?

[HangTime]

Are there any parameters which can be added to the "ls" command to recursively list files within subdirectories? Basically I need something which will list all the files within a given directory including all subdirectories - the same as what dir/s does in DOS.

Forgive the 'newbie' question, but I've never really used a unix CLI before.

Thanks.

Next question - how do I dump the results of commands to a text file (equivalent of "> file.txt" in DOS)?
