The README advertises macOS support, but the port used constructs that fail on the userland macOS actually ships: - `mapfile` (bash 4+) in 10 spots — macOS ships bash 3.2 as /usr/bin/bash, so a mac user following the README hit "mapfile: command not found" and silently got empty project lists. Replace each with a portable `while IFS= read -r` loop (identical arrays; set -u safe on empty input). - `_z_commafy` used the GNU-only `sed :a;...;ta` label/branch idiom, which errors on BSD/macOS sed (the token footer's thousands separators). Reimplement with awk (already a dependency). - README: correct the macOS line — bash 4+ does NOT ship with macOS; the stock 3.2 now works, and only jq needs brew. Also two correctness nits found in the same review: - zkill/zrestart `--kill-all` was parsed but silently ignored; now it prints a "not implemented in the bash port" notice instead of no-op. - zrepair's smoke-test line said "https://$domain" but probes http://$HOST with a Host header; label now matches what it does. Verified on WSL (bash 5): read-loops produce the same 11 project / 7 domain keys as mapfile; awk commafy matches across 0..1,234,567; empty producer yields a 0-length array; footer renders. 3.2-compat is by static analysis — no bash-4-only constructs remain.

# zbackup_ec2 — pull backups down from the server: a Postgres dump for projects
|
|
# with a "db" config block, plus a zip of server-side data dirs (uploads/archive/dist).
|
|
#
|
|
# Usage:
|
|
# zbackup_ec2 # every project with a remote.path
|
|
# zbackup_ec2 <project> [<project> ...]
|
|
#
|
|
# Output:
|
|
# <paths.backupsEc2>/<project>/<timestamp>_<project>_db.sql (projects with a db block)
|
|
# <paths.backupsEc2>/<project>/<timestamp>_<project>_files.zip
