CommandNotFoundException errors in Powershell script - amazon-web-services

Question

I'm using this script to try to upload files to an S3 bucket using cURL.
#S3 parameters
$S3KEY="AKIAYZL7ANTULMU355OD"
$S3SECRET="AKIAYZL7ANTULMU355OD"
$S3BUCKET="quixel-ml-team-data"
$S3STORAGETYPE="STANDARD" #REDUCED_REDUNDANCY or STANDARD etc.
$AWSREGION="us-west-2"
file_path="C:\Users\DELL\AppData\Local\Temp\input_settings.txt"
aws_path="seam-removal\"
bucket="${S3BUCKET}"
date=$(date -R)
acl="x-amz-acl:private"
content_type="application/x-compressed-tar"
storage_type="x-amz-storage-class:${S3STORAGETYPE}"
string="PUT\n\n$content_type\n$date\n$acl\n$storage_type\n/$bucket$aws_path${file_path##/*/}"
signature=$(echo -en "${string}" | openssl sha1 -hmac "${S3SECRET}" -binary | base64)
curl -s --retry 3 --retry-delay 10 -X PUT -T "$file_path" \
-H "Host: $bucket.${AWSREGION}.amazonaws.com" \
-H "Date: $date" \
-H "Content-Type: $content_type" \
-H "$storage_type" \
-H "$acl" \
-H "Authorization: AWS ${S3KEY}:$signature" \
"https://$bucket.${AWSREGION}.amazonaws.com$aws_path${file_path##/*/}"
However, I'm getting these errors. Any idea about them? Sorry, I'm a novice at this sort of programming.

You're mixing a PowerShell with a traditional Unix script.
Further, there's no need to call out the external utilities like OpenSSL and Curl since PowerShell has similar capabilities built in. To sign the URL and perform the Upload without using the AWS SDK, the script would look something like this:
$method = 'PUT'
$service = 's3'
$bucket = "SAMPLES3BUCKETNAME"
$key = 'example-s3-key.txt'
$local_file = "test.txt"
$region = 'us-west-2'
$host1 = $bucket + '.s3-' + $region + '.amazonaws.com'
$access_key = 'SAMPLEACCESSKEY'
$secret_key = 'SAMPLESECRETKEY'
function HmacSHA256($message, $secret)
{
$hmacsha = New-Object System.Security.Cryptography.HMACSHA256
$hmacsha.key = $secret
$signature = $hmacsha.ComputeHash([Text.Encoding]::ASCII.GetBytes($message))
return $signature
}
function getSignatureKey($key, $dateStamp, $regionName, $serviceName)
{
$kSecret = [Text.Encoding]::UTF8.GetBytes(("AWS4" + $key).toCharArray())
$kDate = HmacSHA256 $dateStamp $kSecret;
$kRegion = HmacSHA256 $regionName $kDate;
$kService = HmacSHA256 $serviceName $kRegion;
$kSigning = HmacSHA256 "aws4_request" $kService;
return $kSigning
}
function hash($request)
{
$hasher = [System.Security.Cryptography.SHA256]::Create()
$content = [Text.Encoding]::UTF8.GetBytes($request)
$bytes = $hasher.ComputeHash($content)
return ($bytes|ForEach-Object ToString x2) -join ''
}
$now = [DateTime]::UtcNow
$amz_date = $now.ToString('yyyyMMddTHHmmssZ')
$datestamp = $now.ToString('yyyyMMdd')
$signed_headers = 'host'
$credential_scope = $datestamp + '/' + $region + '/' + $service + '/' + 'aws4_request'
$canonical_querystring = 'X-Amz-Algorithm=AWS4-HMAC-SHA256'
$canonical_querystring += '&X-Amz-Credential=' + [uri]::EscapeDataString(($access_key + '/' + $credential_scope))
$canonical_querystring += '&X-Amz-Date=' + $amz_date
$canonical_querystring += '&X-Amz-Expires=300'
$canonical_querystring += '&X-Amz-SignedHeaders=' + $signed_headers
$canonical_headers = 'host:' + $host1 + "`n"
$canonical_request = $method + "`n"
$canonical_request += "/" + $key + "`n"
$canonical_request += $canonical_querystring + "`n"
$canonical_request += $canonical_headers + "`n"
$canonical_request += $signed_headers + "`n"
$canonical_request += "UNSIGNED-PAYLOAD"
$algorithm = 'AWS4-HMAC-SHA256'
$canonical_request_hash = hash -request $canonical_request
$string_to_sign = $algorithm + "`n"
$string_to_sign += $amz_date + "`n"
$string_to_sign += $credential_scope + "`n"
$string_to_sign += $canonical_request_hash
$signing_key = getSignatureKey $secret_key $datestamp $region $service
$signature = HmacSHA256 -secret $signing_key -message $string_to_sign
$signature = ($signature|ForEach-Object ToString x2) -join ''
$canonical_querystring += '&X-Amz-Signature=' + $signature
$request_url = "http://" + $host1 + "/" + $key + "?" + $canonical_querystring
# Write-Host $request_url
# Using Curl:
# curl.exe '-s', '--retry', '3', '--retry-delay', '10', '-X', 'PUT', '-T', $local_file, $request_url
# Or just put to the URL directly:
Invoke-RestMethod -Uri $request_url -Method Put -InFile $local_file
