packages/bare-os-booter/lib/shell.js
$(...)/backticks are now enabled by default unless explicitly disabled via BARE_OS_SHELL_CMDSUBST=0|false|off.
Fixed sh -c exit/status propagation:
packages/bare-os-booter/lib/shell.js
Syncs BARE_OS_EXIT_STATUS after each executed statement so later commands in the same line (like echo $?) see the immediately previous status.
packages/bare-os-coreutils/src/sh.js
In -c mode, reads final BARE_OS_EXIT_STATUS back into ctx.exitCode for consistent result propagation.
Implemented trap behavior for requested scope (EXIT, INT, TERM):
packages/bare-os-booter/lib/shell.js
exit builtin now runs EXIT trap handler before requesting booter exit.
packages/bare-os-booter/index.js
Signal delivery for shell PID now triggers trap dispatch for INT/TERM.
Hardened ulimit -f invalid diagnostics:
packages/bare-os-coreutils/src/ulimit.js
Explicit invalid-value error for malformed -f setter input, with nonzero exit.
Supported-but-unimplemented setter values still return explicit unsupported-setter error.
if=/dev/zero with finite count*bs now produces requested size directly (not limited by VFS 64KiB pseudo-file).
Raw stdout now uses bareOsEmitRaw, improving pipeline correctness.
Fixed pipeline capture path for FIFO-relevant commands
echo and cat now emit via bareOsEmitRaw (packages/bare-os-coreutils/src/echo.js, packages/bare-os-coreutils/src/cat.js).
Shell pipeline now injects bareOsBinWrite into child contexts when output is captured, so raw writes are captured (packages/bare-os-booter/lib/shell.js).
Improved xattr behavior in packages/bare-os-coreutils/src/xattr.js
Added -p/--print NAME.
-w now logs written attribute name for visible success feedback.
Roundtrip behaviors preserved with sidecar metadata format.
Improved ACL UX in:
packages/bare-os-coreutils/src/getfacl.js
Explicit source header for sidecar and mode fallback (non-compact mode).
packages/bare-os-coreutils/src/setfacl.js
Added -m/--modify ENTRY in addition to stdin blob and -b.
Implemented dynamic ulimit output in packages/bare-os-coreutils/src/ulimit.js
Reads /proc/bare_os/rlimits.json when available.
Supports -a, -n, -Sn, -Hn.
Added shuf -e support in packages/bare-os-coreutils/src/shuf.js.
Added split byte-suffix parsing (k/K/m/M/g/G) and attached -bSIZE support in packages/bare-os-coreutils/src/split.js.
