Why am I getting gibrish result in windows terminal?-CodePudding

I am trying to compare version in windows terminal. It works greate in Git Bash but in windows terminal it shows gibrish and wrong result?

verlte() {
    [  "$1" = "`echo -e "$1\n$2" | sort -V | head -n1`" ]
}

verlt() {
    [ "$1" = "$2" ] && return 1 || verlte $1 $2
}

verlte 2.5.7 2.5.6 && echo "yes" || echo "no" # no
verlt 2.4.10 2.4.9 && echo "yes" || echo "no" # no
verlt 2.4.8 2.4.10 && echo "yes" || echo "no" # yes
verlte 2.5.6 2.5.6 && echo "yes" || echo "no" # yes
verlt 2.5.6 2.5.6 && echo "yes" || echo "no" # no

Result in windows terminal

Result in Git Bash

Borrowing from Sort a list that contains version numbers properly, which references How to sort by file name the same way Windows Explorer does?, here's my attempt at converting to PowerShell syntax:

# compare two arbitrary version strings using natural sorting
# allows strings to contain non-numeric components
function verlte {
    param(
        [string]$v1,
        [string]$v2
    )

    function ToNatural {
        param( [string]$v )
        [regex]::Replace($v, '\d ', { $args[0].Value.PadLeft(20) })
    }
    
    (ToNatural $v1) -le (ToNatural $v2)
}

function verlt {
    param(
        [string]$v1,
        [string]$v2
    )

    if ($v1 -eq $v2) { return $false }
    verlte $v1 $v2
}

verlte 2.5.7 2.5.6 # False
verlt 2.4.10 2.4.9 # False
verlt 2.4.8 2.4.10 # True
verlte 2.5.6 2.5.6 # True
verlt 2.5.6 2.5.6 # False

It seems you're comparing versions. In PowerShell and .NET framework there are already [version] to do that:

PS C:\Users> [version]"2.5.7" -le [version]"2.5.6"
False
PS C:\Users> [version]"2.4.10" -lt [version]"2.4.9"
False
PS C:\Users> [version]::new(2, 4, 8) -lt [version]::new(2, 4, 10)
True
PS C:\Users> [version]"2.5.6" -le [version]"2.5.6"
True
PS C:\Users> [version]::new(2, 5, 6) -lt [version]::new(2, 5, 6)
False
