pwd -P produces incorrect output

[amancevice]

• Task version: Task version: v3.7.0 (h1:8dDFv12/Lxi6PHkYNIIm7N6v6oRGxePpLK67LuMh/Rs=)
• Operating System: macOS 11.5.1 (Big Sur)

Example Taskfile showing the issue

Reproduce with the following steps:

mkdir ~/tmpdir
ln -s ~/tmpdir ~/tmplink
cd ~/tmplink
pwd -P
# => /Users/<user>/tmpdir

Using the following Taskfile:

version: "3"
tasks:
  default:
    cmds:
      - pwd -P

Output is:

task: [default] pwd -P
/Users/<user>/tmplink

Interestingly, changing the command to sh -c 'pwd -P' seems to work as expected!

Hi @amancevice,

This seems like a bug on the shell interpreter library Task uses: https://github.com/mvdan/sh

sh -c 'pwd -P' works because sh -c bypasses the library and runs the command in the system's shell.

Would you mind opening an issue there explaining the problem?
