PUBLICSHARE台録に対応するのはSpecial Folderにはないかな？

Windows	XDG
Desktop	DESKTOP
[^1]	DOWNLOAD
Templates	TEMPLATES
（なし？）	PUBLICSHARE
MyDocuments	DOCUMENTS
MyMusic	MUSIC
MyPictures	PICTURES
MyVideos	VIDEOS

/mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe \

うまくいかない

#!/bin/sh

set -v
set -- Desktop=DESKTOP Templates=TEMPLATES MyDocuments=DOCUMENTS \
       MyMusic=MUSIC MyPictures=PICTURES MyVideo=VIDEOS

while [ $# -gt 0 ]; do
    printf '%s="%s"\n' \
      "${1#*=}" \
        "$(/mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe \
           -Command '[Environment]::GetFolderPath("'${1%=*}'")')"
    #  "$(wslpath -a -u \
    #   )"
    shift
done

うまくいかない原因は，PowerShellの（既定の？←つまり変更可能かもしれない）改行が送行・復帰で構成されていることだった。

#!/bin/sh

set -- Desktop=DESKTOP Templates=TEMPLATES MyDocuments=DOCUMENTS \
       MyMusic=MUSIC MyPictures=PICTURES MyVideo=VIDEOS

while [ $# -gt 0 ]; do
    printf '%s="%s"\n' \
      "${1#*=}" \
      "$(wslpath -a -u \
        "$(/mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe \
           -Command '[Console]::Write([Environment]::GetFolderPath("'"${1%=*}"'"))'
       )")"
    shift
done
