```
### Excluding languages
Put a `-` in front of a language to remove it from the selection. This works on `-l`,
`-vl`, `-al`, `-sl`, and `-fsl`, in the same way as it works on `-w` / `--wanted`.
```shell title="Every subtitle language except Spanish"
unshackle dl -sl all,-es EXAMPLE 81234567
```
The exclusions are subtracted from the languages the flag would otherwise select, and the
order of the values does not matter. If you give only exclusions, the flag keeps its own
default: `-sl -es` is the same as `-sl all,-es`, and `-l -es` is the same as `-l orig,-es`.
```shell title="Only exclusions"
# every subtitle language except Spanish and French
unshackle dl -sl -es,-fr EXAMPLE 81234567
# the original audio language, unless it is Spanish
unshackle dl -l -es EXAMPLE 81234567
```
`-vl` and `-al` have no default of their own: they cascade to `-l`. An override that names
a language replaces `-l` for that stream type, exclusions included. An override that gives
only exclusions adds them to the ones from `-l`.
```shell title="Cascade"
# video keeps the Japanese track; only the audio drops Spanish
unshackle dl -l en,-es -vl ja EXAMPLE 81234567
```
!!! note "Rules for exclusion tokens"
- `orig` is resolved per title, so `-sl -orig` drops the subtitles in the title's
original language.
- `--exact-lang` applies to exclusions with the same matching rules as selection:
`-es` removes exactly the tracks that `es` would select. Without it, `-es` also
removes `es-419` and `es-ES`.
- Tracks with no language tag are never excluded.
- `-all` is rejected. Name the languages you do not want instead.
- The comma form is the documented style. `-sl -es` also works, but a shell can read
a lone `-es` as another option.
