#tac
Reverse record order for MoonX.
moonx cli/tac@0.1.6 [OPTION]... [FILE]...#Supported scope
Reverse records from each file or stdin, preserving separator bytes and missing final separators. Default separator is LF.
#Options
| Option | Description |
|---|---|
| -s, --separator=STRING | Set a separator; empty fixed separator means NUL. |
| -b, --before | Attach separators to the following record. |
| -r, --regex | Interpret the separator using GNU Emacs byte regex syntax. |
| --help / --version | Show help / package version. |
#Limitations
The local development candidate batches fixed-separator ranges within each 64 KiB block, including multi-byte separators. With no partial separator match, it skips bytes that cannot start a reverse match. Input spooling and cross-block record semantics are unchanged; memory remains bounded by the block and separator sizes.
- Empty regex separators and locale-aware matching are unsupported.
- A local GNU 9.11 comparison retains a long repeated-input difference with the overlapping fixed separator aa; see ADR-0003.
- Stdin/nonregular inputs and regex mode require temporary storage. Regex mode also retains input in memory.
- Temporary cleanup failures are reported after successful processing. An earlier read or output failure keeps its original diagnostic if cleanup also fails.
