Package: dash
Version: 0.5.12-6
Hello,
I use actually dash on Fedora version 0.5.12-1.fc38, but the only way to
report bugs towards dash seems to be the Debian bug tracker system.

says:
2.3.1 Alias Substitution
When used as specified by this volume of POSIX.1-2017, alias definitions
shall not be inherited by separate invocations of the shell or by the
utility execution environments invoked by the shell.
So a subshell shall have no knowledge about the aliases from the
supershell, and backticks start a subshell.
These programs
#!/bin/bash
alias wslpath=echo
find `wslpath /tmp`
and
#!/bin/dash
alias wslpath=echo
find `wslpath /tmp`
produce different results (bash 5.2.15-3.fc38) when executed on a WSL2
system. The former program shows the content of the current directory,
the latter program shows the content of /tmp .
Kind regards
Dilyan
