How to detect Visual Studio installation path from Git Bash, Cygwin, MSYS2 etc.

find-visual-studio-path.sh

#!/usr/bin/env bash
[[ -t 1 ]] && { cG="\e[1;32m"; cR="\e[1;31m"; cB="\e[1;34m"; cW="\e[1;37m"; cY="\e[1;33m"; cG_="\e[0;32m"; cR_="\e[0;31m"; cB_="\e[0;34m"; cW_="\e[0;37m"; cY_="\e[0;33m"; cZ="\e[0m"; export cR cG cB cY cW cR_ cG_ cB_ cY_ cW_ cZ; }
for tool in env gawk tr; do type $tool > /dev/null 2>&1 || { echo -e "${cR}ERROR:${cZ} couldn't find '$tool' which is required by this script."; exit 1; }; done

function VsWhereLatest
{
    for tool in cygpath; do type $tool > /dev/null 2>&1 || { echo -e "${cR}ERROR:${cZ} couldn't find '$tool' which is required by this script."; exit 1; }; done
    # Bash chokes on variable names with embedded parentheses, hence this mumbo jumbo
    local PF86="$(cygpath -u "$(env|tr -d '\r'|gawk -F= '$1 == "ProgramFiles(x86)" {print $2}')")"
    # This is a well-known path that _can_ legitimately be hardcoded as per Microsoft!
    local VSWHERE="$PF86/Microsoft Visual Studio/Installer/vswhere.exe"
    echo -e "${cW}VSWHERE${cZ}=$VSWHERE" > /dev/stderr
    if [[ -f "$VSWHERE" && -x "$VSWHERE" ]]; then
        # Result of the following line will be something like: C:\Program Files\Microsoft Visual Studio\2022\Professional
        local WIN_VSINSTPATH="$(set -x; "$VSWHERE" -products \* -format value -property installationPath -latest|tr -d '\r')"
        # Result of the following line will be something like: /c/Program Files/Microsoft Visual Studio/2022/Professional
        # Note: depending on your environment a prefix like /cygdrive may have been prepended as well.
        local VSINSTPATH="$(cygpath -u "$WIN_VSINSTPATH")"
    fi
    echo "$VSINSTPATH"
}

VSINSTPATH=$(VsWhereLatest)
if [[ -n "$VSINSTPATH" ]]; then
	echo -e "${cW}VSINSTPATH${cZ}=$VSINSTPATH"
else
	echo -e "${cR}ERROR:${cZ} Could not determine path of latest Visual Studio installation."
	exit 1
fi

Small update to tackle the \r in the output of vswhere.exe and delete that for further use in a variable.
