How to expand wildcard inside shell code block in a Makefile? - shell

Question

I got this script which reads a delimited part of my .gitignore file and remove all files after the given mark # #:

readarray -td' ' GARBAGE_DIRECTORIES <<<"$(DIRECTORIES_TO_CLEAN) "; \
unset 'GARBAGE_DIRECTORIES[-1]'; \
declare -p GARBAGE_DIRECTORIES; \
readarray -td' ' GARBAGE_EXTENSIONS <<<"$(GITIGNORE_CONTENTS) "; \
unset 'GARBAGE_EXTENSIONS[-1]'; \
declare -p GARBAGE_EXTENSIONS; \
for filename in "$${GARBAGE_DIRECTORIES[#]}"; \
do \
arraylength="$${#GARBAGE_EXTENSIONS[#]}"; \
printf 'Cleaning %s extensions on %s\n' "$${arraylength}" "$$filename"; \
for extension in "$${GARBAGE_EXTENSIONS[#]}"; \
do \
[[ ! -z "$$filename" ]] || continue; \
[[ ! -z "$$extension" ]] || continue; \
full_expression="$${filename}/$${extension}" ;\
printf '%s\n' "$$full_expression"; \
rm -v "$$full_expression"; \
done; \
done;
Running it with the following .gitignore file:
*.txt
*.var
# Comment #
*.aux
The rm command is not expanding the wildcards and keeps telling me rm: cannot remove './*.aux': No such file or directory and do not remove the *.aux files from the ./ directory.
Update
After asked on a comment by #Beta, I simplified the Makefile to this:
GITIGNORE_CONTENTS := "*.aux" "*.lof"
DIRECTORIES_TO_CLEAN := "./setup/cache" "./setup/cache/chapters"
clean:
readarray -td' ' GARBAGE_DIRECTORIES <<<"$(DIRECTORIES_TO_CLEAN) "; \
unset 'GARBAGE_DIRECTORIES[-1]'; \
declare -p GARBAGE_DIRECTORIES; \
readarray -td' ' GARBAGE_EXTENSIONS <<<"$(GITIGNORE_CONTENTS) "; \
unset 'GARBAGE_EXTENSIONS[-1]'; \
declare -p GARBAGE_EXTENSIONS; \
for filename in "$${GARBAGE_DIRECTORIES[#]}"; \
do \
arraylength="$${#GARBAGE_EXTENSIONS[#]}"; \
printf 'Cleaning %s extensions on %s\n' "$${arraylength}" "$$filename"; \
for extension in "$${GARBAGE_EXTENSIONS[#]}"; \
do \
[[ ! -z "$$filename" ]] || continue; \
[[ ! -z "$$extension" ]] || continue; \
full_expression="$${filename}/$${extension}" ;\
printf '%s\n' "$$full_expression"; \
rm -vf "$$full_expression"; \
done; \
done;
Which results on this output after running it:
$ make
readarray -td' ' GARBAGE_DIRECTORIES <<<""./setup/cache" "./setup/cache/chapters" "; \
unset 'GARBAGE_DIRECTORIES[-1]'; \
declare -p GARBAGE_DIRECTORIES; \
readarray -td' ' GARBAGE_EXTENSIONS <<<""*.aux" "*.lof" "; \
unset 'GARBAGE_EXTENSIONS[-1]'; \
declare -p GARBAGE_EXTENSIONS; \
for filename in "${GARBAGE_DIRECTORIES[#]}"; \
do \
arraylength="${#GARBAGE_EXTENSIONS[#]}"; \
printf 'Cleaning %s extensions on %s\n' "${arraylength}" "$filename"; \
for extension in "${GARBAGE_EXTENSIONS[#]}"; \
do \
[[ ! -z "$filename" ]] || continue; \
[[ ! -z "$extension" ]] || continue; \
full_expression="${filename}/${extension}" ;\
printf '%s\n' "$full_expression"; \
rm -vf "$full_expression"; \
done; \
done;
declare -a GARBAGE_DIRECTORIES=([0]="./setup/cache" [1]="./setup/cache/chapters")
declare -a GARBAGE_EXTENSIONS=([0]="*.aux" [1]="*.lof")
Cleaning 2 extensions on ./setup/cache
./setup/cache/*.aux
./setup/cache/*.lof
Cleaning 2 extensions on ./setup/cache/chapters
./setup/cache/chapters/*.aux
./setup/cache/chapters/*.lof
More simplification
I reduced to the more simple version it could be:
clean:
rm -v "./setup/cache/*.aux";
Running this, also do not remove the files:
$ make
rm -v "./setup/cache/*.aux";
rm: cannot remove './setup/cache/*.aux': No such file or directory
make: *** [Makefile:3: clean] Error 1
$ ls ./setup/cache/*.aux
./setup/cache/main.aux
On above, after running ls, you can see the file still exists and it is there.

Answer 1

I managed to fix it by changing:
rm -vf "$$full_expression"; \
To:
rm -vf $${full_expression}; \
