I'm wanting to rename
123/1/ -> 123/v1/
foo/1/ -> foo/v1/
bar/1/ -> bar/v1/
345/1/ -> 345/v1/
I've searched and found a few related solutions, but not quite sure what is best in this instance. e.g.,
find . -wholename "*/1" -exec echo '{}' \;
successfully prints out all the paths relative to ., but {} expands to ./foo/1/, so I can't move from {} to {}/v1 for instance. I also tried
find . -wholename "*/1" -exec mv '{}' $(echo '{}' | sed 's/1/v1/') \;
with the idea that I would be invoking mv ./foo/1 ./foo/v1, but apparently it tries to move .foo/1/ to a subdirectory of itself.
Anyhow, just looking for the simplest way to do this bulk renaming. To be clear, I'm trying to move the literal subdirectory 1 to v1, not also 2 to v2.
Like this, using perl rename (which may be different than the rename already existing on your system, use rename --version to check):
rename -n 's|([^/]+/)(1)|$1v$2|' */1/
remove -n (dry-run) when the outputs is ok for you.
(note that you can use globstar on bash or something similar on other shells to recurse into deeper sub-directories)
