Recommended action: Use a form that works on both: attach a suffix ('sed -i.bak ... file && rm file.bak'), or avoid -i (write to a temp file and mv), or install GNU sed (gsed) on macOS and call it explicitly.
Option: Use an attached backup suffix that both seds accept [evidence: documented_workaround]
Applies when: Scripts that must run on macOS and Linux
Steps:
1. Replace 'sed -i ...' with 'sed -i.bak -e ... file'
2. Remove the backup: 'rm file.bak'
Expected: Same behavior on BSD and GNU sed
Option: Install GNU sed on macOS [evidence: documented_workaround]
Applies when: Developer machines/macOS CI where GNU semantics are assumed
Steps:
1. brew install gnu-sed
2. Call gsed, or put the gnubin directory first in PATH
Expected: GNU sed semantics on macOS
