- This is GNU cpio. Its main advantages over the Unix versions are:
-
- * It can use any I/O block size, with `+block-size'.
-
- * `-o' and `-p' can copy symbolic links either as symbolic links or,
- with `-L', as the files they point to.
-
- * `-i' automatically recognizes ASCII, binary, and byte-swapped binary
- cpio archives, and skips any junk between files, to try to recover
- from corrupted archives. `-b' and `-c' force it to only recognize
- binary (either byte ordering) or ASCII archives.
-
- * The output of '-itv' looks like 'ls -l'.
-
- * It accepts long-named options as well as traditional
- single-character options.
-
- Some features of other versions of cpio are missing from GNU cpio, including:
-
- * Byte swapping of data with `-i'.
- -b swap bytes and 16-bit words within each 32-bit word
- -s swap bytes within each 16-bit half-word (dd conv=swab can do this)
- -S swap 16-bit words within each 32-bit word
-
- * The `-6' option to support Sixth Edition Unix cpio archives with `-i'.
-
- * `-s' option to limit volume size, like afio.
