Given the folder structure
/recipes/foo/.env
/recipes/bar/.env
Running the following command:
find ./recipes -type f -name '.env' -print0 | xargs -0 dirname | xargs -0 basename
Output:
foo
Trimming the command down to:
find ./recipes -type f -name '.env' -print0 | xargs -0 dirname
Output:
./recipes/bar
./recipes/foo
So for some reason piping dirname to basename causes me to lose some of the found directories.
0
There are 2 issues here:
-
The
-0option ofxargsindicates that the inputs are NUL-separated, not the outputs. In order to pipe the output ofxargs -0 dirnametoxargs -0 somethingyou must use the-zoption ofdirnameif it is supported (it is not POSIX). Else, its output is newline-separated. -
basenamedoes not support multiple arguments by default. If yours supports it (it is not POSIX) you can try-aor--multiple.find ./recipes -type f -name '.env' -print0 | xargs -0 dirname -z | xargs -0 basename -aElse, use the
-n1option ofxargs:find ./recipes -type f -name '.env' -print0 | xargs -0 dirname -z | xargs -0 -n1 basename
Note: as your find is apparently GNU find you could skip dirname with:
find ./recipes -type f -name '.env' -printf '%h' | xargs -0 basename -a
Note: you could also use only find and any POSIX shell:
find ./recipes -type f -name '.env' -exec sh -c '
d="${1%/*}"; printf "%sn" "${d##*/}"' _ {} ;
Note: if, like in the example you show, the depth of the .env files is 2 you don’t need find, xargs, dirname or basename. Your (POSIX) shell is enough (plus the printf utility if it is not already a built-in of your shell):
for f in recipes/*; do [ -f "$f/.env" ] && printf '%sn' "${f##*/}"; done
