It is designed to be used with the Linux shell. In addition, you can preview your files in the browser. In this article, we will show how to use transfer.sh in Linux.

Upload a Single File

To upload a file, you can use the curl program with the --upload-file option as shown.

$ curl --upload-file ./tecmint.txt https://transfer.sh/tecmint.txt

Download a File

To download your file, a friend or colleague can run the following command.

$ curl https://transfer.sh/Vq3Kg/tecmint.txt -o tecmint.txt 

Upload Multiple Files

You can upload multiple files at once, for example:

$ curl -i -F [email protected]/path/to/tecmint.txt -F [email protected]/path/to/usernames.txt https://transfer.sh/ 

Encrypt Files Before Transfer

To encrypt your files before the transfer, use the following command (you must have the gpg tool installed on the system). You will be prompted to enter a password to encrypt the file.

$ cat usernames.txt | gpg -ac -o- | curl -X PUT --upload-file "-" https://transfer.sh/usernames.txt 

To download and decrypt the above file, use the following command:

$ curl https://transfer.sh/11Rnw5/usernames.txt | gpg -o- > ./usernames.txt

Use Wget Tool

Transfer.sh also supports the wget tool. To upload a file, run.

$ wget --method PUT –body-file=./tecmint.txt https://transfer.sh/tecmint.txt -O --nv 

Create Alias Command

To use the short transfer command, add an alias to your .bashrc or .zshrc startup file.

$ vim ~/.bashrc
OR
$ vim ~/.zshrc

Then add the lines below in it (you can only choose one tool, either curl or wget).

##using curl
transfer() {
    curl --progress-bar --upload-file "$1" https://transfer.sh/$(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 $1)" https://transfer.sh/$(basename $1);
}

alias transfer=transfer

Save the changes and close the file. Then source it to apply the changes.

$ source ~/.bashrc
OR
$ source ~/.zshrc

From now on, you upload a file using the transfer command as shown.

$ transfer users.list.gz

To setup your own sharing server instance, download the program code from the Github repository.
