…as a no-op
tests/e2e/template_instantiation_test.sh ran:
find ... -exec bash -c '
file="$1"
... grep/sed over $file ...
' _ "$file"
Two defects in that one line:
1. No ';' or '+' terminator, so the file does not parse (SC2067).
2. "$file" is passed where {} belongs. $file is assigned ONLY inside the
-exec body, so in the outer scope it is UNSET — $1 arrived empty, file=""
and every grep/sed operated on an empty path.
⚠ The consequence is worse than a lint error: the placeholder-replacement step
SILENTLY DID NOTHING, then logged "All placeholder tokens replaced". A test
whose whole purpose is to prove instantiation worked was passing without
replacing a single token. That is a plausible cause of estate repos shipping
with literal {{project}} tokens still in their sources.
Corrected to "' _ {} \;" so find passes each matched path.
Found by an estate-wide shellcheck sweep of 5,111 scripts across 375 repos:
this identical stale copy exists in 30 repositories. rsr-template-repo's own
copy is already correct and restructured (371 lines vs the 268 here), so these
are stale duplicates that never picked up the upstream fix.

Pass the placeholder values to the child shell.
bash -c does not inherit ordinary shell variables. The variables assigned on Lines 18-27 are not exported, so $TEST_REPO_NAME, $TEST_OWNER, $TEST_FORGE, $TEST_PROJECT_NAME, $TEST_DESCRIPTION, $TEST_PRIMARY_LANGUAGE, $TEST_AUTHOR, and $TEST_AUTHOR_EMAIL expand to empty strings in the child shell. The now-active find -exec therefore deletes most placeholder values while the test can still report success. Export these variables before find, or pass them as additional bash -c arguments.
Proposed fix
+# Make values available to the `bash -c` child process.

Pull Request Overview
While this PR correctly identifies and addresses the syntax error in the find -exec command, the implementation remains non-functional (a 'no-op'). The subshell invoked by sh -c uses single quotes, which prevents the parent shell from expanding the $placeholder and $value variables. Consequently, these variables are empty within the subshell, and the template replacement logic will not execute as intended.
Codacy reports the PR is up to standards, but this refers to static analysis rather than the logic flaw described above. To meet the acceptance criteria of ensuring placeholders are actually replaced, the command must be restructured to pass local variables as arguments to the subshell.
About this PR
- The fix provided corrects the shell syntax but does not yet achieve the goal of making the placeholder replacement functional. The variables inside the find execution block remain inaccessible to the subshell.
Test suggestions
- Verify that template placeholders are actually replaced with provided values in the output files.
- Ensure the find command correctly iterates over all target files and executes the substitution block.
- Verify that $placeholder and $value variables are correctly propagated into the subshell environment.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify that $placeholder and $value variables are correctly propagated into the subshell environment.

🔴 HIGH RISK
The shell script inside 'sh -c' is single-quoted, which prevents the parent shell from expanding variables. While adding '{} ;' fixes the find syntax error, variables like $placeholder and $value will be empty inside the subshell. Furthermore, since the script fragment on line 139 concludes with a 'done' statement, using '+' instead of ';' is more efficient as it allows 'find' to batch multiple files into fewer shell invocations.
Consider updating the command to pass the variables as arguments:
find ... -exec sh -c 'p="$1"; v="$2"; shift 2; for file in "$@"; do ... done' _ "$placeholder" "$value" {} +1 participant
