Chapter 3: Guided Tour

COMMITTED

The last revision in which an item changed before (or at)

BASE.

PREV

The revision just before the last revision in which an item changed. (Technically,

COMMITTED - 1.)

Here are some examples of revision keywords in action. Don’t worry if the com-

mands don’t make sense yet; we explain these commands as we go through the chap-

ter:

$ svn diff --revision PREV:COMMITTED foo.c

# shows the last change committed to foo.c

$ svn log --revision HEAD

# shows log message for the latest repository commit

$ svn diff --revision HEAD

# compares your working file (with local mods) to the latest version

# in the repository.

$ svn diff --revision BASE:HEAD foo.c

# compares your "pristine" foo.c (no local mods) with the

# latest version in the repository

$ svn log --revision BASE:HEAD

# shows all commit logs since you last updated

$ svn update --revision PREV foo.c

# rewinds the last change on foo.c.

# (foo.c's working revision is decreased.)

These keywords allow you to perform many common (and helpful) operations with-

out having to look up specific revision numbers or remember the exact revision of

your working copy.

Anywhere that you specify a revision number or revision keyword, you can also spec-
