Easy and fast file sharing from the command-line. This code contains the server with everything you need to create your own instance. currently supports the s3 (Amazon S3), gdrive (Google Drive) providers, and local file system (local).



$ curl --upload-file ./hello.txt

Encrypt & upload:

$ cat /tmp/hello.txt|gpg -ac -o-|curl -X PUT --upload-file "-"

Download & decrypt:

$ curl|gpg -o- > /tmp/hello.txt

Upload to virustotal:

$ curl -X PUT --upload-file nhgbhhj

Add alias to .bashrc or .zshrc

Using curl

transfer() {
    curl --progress-bar --upload-file "$1"$(basename $1) | tee /dev/null;

alias transfer=transfer

Using wget

transfer() {
    wget -t 1 -qO - --method=PUT --body-file="$1" --header="Content-Type: $(file -b --mime-type $1)"$(basename $1);

alias transfer=transfer

Add alias for fish-shell

Using curl

function transfer --description 'Upload a file to'
    if [ $argv[1] ]
        # write to output to tmpfile because of progress bar
        set -l tmpfile ( mktemp -t transferXXX )
        curl --progress-bar --upload-file "$argv[1]" $argv[1]) >> $tmpfile
        cat $tmpfile
        command rm -f $tmpfile
        echo 'usage: transfer FILE_TO_TRANSFER'

funcsave transfer

Using wget

function transfer --description 'Upload a file to'
    if [ $argv[1] ]
        wget -t 1 -qO - --method=PUT --body-file="$argv[1]" --header="Content-Type: (file -b --mime-type $argv[1])" $argv[1])
        echo 'usage: transfer FILE_TO_TRANSFER'

funcsave transfer

Now run it like this:

$ transfer test.txt

Add alias on Windows

Put a file called transfer.cmd somewhere in your PATH with this inside it:

@echo off
:: use env vars to pass names to PS, to avoid escaping issues
set FN=%~nx1
set FULL=%1
powershell -noprofile -command "$(Invoke-Webrequest -Method put -Infile $Env:FULL$Env:FN).Content"

Link aliases

Create direct download link: -->

Inline file: -->


Parameter Description Value Env
listener port to use for http (:80)
profile-listener port to use for profiler (:6060)
force-https redirect to https false
tls-listener port to use for https (:443)
tls-listener-only flag to enable tls listener only
tls-cert-file path to tls certificate
tls-private-key path to tls private key
http-auth-user user for basic http auth on upload
http-auth-pass pass for basic http auth on upload
temp-path path to temp folder system temp
web-path path to static web files (for development)
ga-key google analytics key for the front end
uservoice-key user voice key for the front end
provider which storage provider to use (s3, grdrive or local)
aws-access-key aws access key AWS_ACCESS_KEY
aws-secret-key aws access key AWS_SECRET_KEY
bucket aws bucket BUCKET
basedir path storage for local/gdrive provider
gdrive-client-json-filepath path to oauth client json config for gdrive provider
gdrive-local-config-path path to store local config cache for gdrive provider
gdrive-chunk-size chunk size for gdrive upload in megabytes, must be lower than available memory (8 MB)
lets-encrypt-hosts hosts to use for lets encrypt certificates (comma seperated)
log path to log file

If you want to use TLS using lets encrypt certificates, set lets-encrypt-hosts to your domain, set tls-listener to :443 and enable force-https.

If you want to use TLS using your own certificates, set tls-listener to :443, force-https, tls-cert=file and tls-private-key.


Make sure your GOPATH is set correctly.

go run main.go --provider=local --listener :8080 --temp-path=/tmp/ --basedir=/tmp/


go build -o transfersh main.go


For easy deployment, we've created a Docker container.

docker run --publish 8080:8080 dutchcoders/ --provider local --basedir /tmp/
