Describe the bug

A clear and concise description of what the bug is.

I built my application as specified in the documentation and use it as specified in https://cli.urfave.org/v2/examples/bash-completions/
However, when you press TAB on the command line with an incomplete sub-command name, nothing happens.

To reproduce

PROG=./out/bin/myprog source ./scripts/bash_autocomplete
./out/bin/myprog subcomm[press TAB]

Observed behavior

Nothing happens.

Expected behavior

bash auto-complete command in command-line to "subcommand".

@Aleksei-Badyaev Can you try PROG=myprog source ./scripts/bash_autocomplete ?

@Aleksei-Badyaev Can you try PROG=myprog source ./scripts/bash_autocomplete ?

I've already done that. I wrote above that I did everything exactly according to the documentation.

@Aleksei-Badyaev does the autocomplete work when you just press ./out/bin/myprog <TAB> without the subcommand ?

See #1905 and #1874

We plan on making shell completion easier to use in v3.

NO - nothing happens.

Hey Aleksei,

I have 3 simple Go CLI programs that are built with urfave/cli/v3 (not v2) and they support shell completion just fine. You might want to check them out as examples:

• https://github.com/bartekpacia/emu
• https://github.com/bartekpacia/fhome

If you're on mac, you can install them with Homebrew: e.g. brew install bartekpacia/tools/emu
