tzxcutCuts out blocks from a TZX file into a new TZX file.
This tool is useful to split the copy of a mixed tape into a separate TZX file for one of the programs.
See also tzxsplit.
This tool also accepts a TAP file. It is converted to TZX format internally.
tzxcut [-h] [-i SOURCE] [-o TARGET] [-v] [blocks [blocks ...]]
blocks: Block number, or range of block numbers, to keep in the output file. Use tzxls to find out the block numbers of a TZX file.-i, --from: TZX file to read from, or stdin if not given.-o, --to: Target file. If omitted, stdout is used.-v, --invert: Invert block matches. The given block numbers are not kept, but removed.-h, --help: Show help message and exit.Blocks can be addressed in a single number or in a range:
13 - Keep block number 13.4:8 - Keep block numbers 4 to 8 (inclusive).3: - Keep block numbers 3 and higher.:4 - Keep the first blocks up to block 4 (inclusive).Remember that blocks are counted starting from zero.
Negative block numbers are counted backwards from the last block:
-1 - Keep only the last block.4:-2 - Keep block numbers from 4 up to the second to last block.-4: - Keep the last four blocks.:-3 - Keep all the blocks up the third to last block.If you use negative block numbers, it is wise to place a -- at the command line before the block ranges, so negative block numbers are not interpreted as options (see example below).
tzxcut -i games.tzx -o first-game.tzx 0:5 7
Copies the blocks 0 to 5 (inclusive) and block 7 of games.tzx into a new file first-game.tzx.
tzxcut -i games.tzx -o first-game.tzx -- -5 -3:
Copies the fifth to last and the three last blocks of games.tzx into a new file first-game.tzx.
