Details:
In the find(1) manual entry, there is this example:
Given the following directory of projects and their associated SCM
administrative directories, perform an efficient search for the projects'
roots:
$ find repo/ \
\( -exec test -d '{}/.svn' \; \
-or -exec test -d '{}/.git' \; \
-or -exec test -d '{}/CVS' \; \
\) -print -prune
Sample output:
repo/project1/CVS
repo/gnu/project2/.svn
repo/gnu/project3/.svn
repo/gnu/project3/src/.svn
repo/project4/.git
But the above sample output is very wrong. If the directories listed above
existed, then the output would be:
repo/project1
repo/gnu/project2
repo/gnu/project3
repo/project4
(but not necessarily in that order).
The "/CVS" and "/.svn" and "/.git" sub-directories would not be included in
the output because they don't match the query. It is their parent directories
that match the query.
More importantly, the "repo/gnu/project3/src" directory would not appear
because of the use of -prune which excludes anything under
"repo/gnu/project3". That's the whole point of this example. It prunes the
tree wherever it finds an SCM directory (so it excludes nested project
roots).
It looks like the "Sample output" should really have been listed under "Given
the following directory of projects", and the "Sample output" should have been
completely different.
This example should probably be rewritten to look like this:
Given the following directory of projects and their associated SCM
administrative directories, perform an efficient search for the projects'
roots:
$ find repo/ \
\( -exec test -d '{}/.svn' \; \
-or -exec test -d '{}/.git' \; \
-or -exec test -d '{}/CVS' \; \
\) -print -prune
Sample directories:
repo/project1/CVS
repo/gnu/project2/.svn
repo/gnu/project3/.svn
repo/gnu/project3/src/.svn
repo/project4/.git
Sample output:
repo/project1
repo/gnu/project2
repo/gnu/project3
repo/project4
