Describe your issue

I downloaded Miniforge3-Linux-x86_64.sh, then ran the script. I got the error:

Miniforge3-Linux-x86_64.sh: line 517: [: 1
24: integer expression expected
usage: mamba [-h] [-v] [--no-plugins] [-V] COMMAND ...
mamba: error: argument COMMAND: invalid choice: 'shell' (choose from activate, clean, commands, compare, config, create, deactivate, env, export, info, init, install, list, notices, package, doctor, repoquery, remove, uninstall, rename, run, search, update, upgrade)

I have looked at line 517 of the script:

if [ "$("$PREFIX/bin/mamba" --version | cut -d' ' -f2 | cut -d'.' -f1)" -lt 2 ]; then

If I run:

$PREFIX/bin/mamba --version

I get:

mamba 1.5.12
conda 24.11.3

So the cut commands yield:

1
24

which cannot compare to 2. I think this explains the error. Is this not a bug of the script?
