How do I get a list of files modified between two arbitrary changesets?

hg diff -r 182 -r 193 --stat

or

hg status --rev 182:193

The basic command to look for when you want to know something about file status is hg status. The status command is the file name oriented command and you want to know some file names.

When you run it as

$ hg status

then it compares the working copy state with the working copy parent revision (.). But if you run it as

$ hg status --rev AA:BB

then it will show files modified between AA and BB! No need for grepping, cutting, sorting or templates.

(I've explained this before here, here, and here, please see those questions and answers for more tips.)
