Question

What’s the equivalent of “git clean” with Perforce?

git-clean – Remove untracked files from the working tree

Cleans the working tree by recursively removing files that are not under version control, starting from the current directory.

-x Don’t use the standard ignore rules read from .gitignore (per
directory) and $GIT_DIR/info/exclude, but do still use the ignore
rules given with -e options. This allows removing all untracked files,
including build products. This can be used (possibly in conjunction
with git reset) to create a pristine working directory to test a clean
build.

-X Remove only files ignored by Git. This may be useful to rebuild
everything from scratch, but keep manually created files.

Try (for Unix) from your top-level:

# Find all files and filter for those that are unknown by Perforce
find . -type f | p4 -x - fstat 2>&1 > /dev/null | sed 's/ -.*$//' > /tmp/list
### manually check /tmp/list for files you didn't mean to delete
# Go ahead and remove the unwanted files.
xargs rm < /tmp/list

Or, for a clean -f kind of approach just pipe directly to xargs rm instead of first staging the file list in /tmp/list.
