Highlighting --help messages incompatibility with sdkman and zsh

[ThibaultDelaune-pro]

What steps will reproduce the bug?

1. install sdkman
2. follow the process to highlight help messages with global zsh aliases (with alias -g into the ~/.zshrc)
3. run another shell

What happens?
Any new shell show the following errors

/home/my-home/.sdkman/src/sdkman-env.sh:153: parse error near `>&'
/home/my-home/.sdkman/bin/sdkman-init.sh:114: parse error near `>&'

And sdkman doesn't work anymore.

What did you expect to happen instead?
No error in the shell and sdkman still working.

How did you install bat?

sudo apt install bat

bat version and environment

• bat 0.24.0
• zsh 5.9 (x86_64-ubuntu-linux-gnu)
• ubuntu - 24.04.3
• sdkman 5.20.0 (native: 0.7.14 - linux x86_64)

I've just identified that the issue comes from the use of the -h conditional expression in the sdkman-env.sh and sdkman-init.sh files.

I've tried to escape them with \ but it doesn't work :

/home/itde4410/.sdkman/src/sdkman-env.sh:1: parse error: condition expected: \-h
/home/itde4410/.sdkman/bin/sdkman-init.sh:114: parse error: condition expected: \-h

So finally, I replaced these by the -L conditional expression :

...
if [[ -L "$candidate_dir" || -d "${candidate_dir}" ]]; then
...
function __sdkman_is_symlink() {
	[[ -L "$1" ]]
}
...

... and that works! 🥳

So if you have an idea to escape these -h in scripts, it would be appreciated. 😄
From what I read, aliases shouldn't be expanded by default in shell scripts unless shopt expand_aliases is set wich it doesn't seems to be the case...
