Sharing or transferring files using is not a big deal. First let us upload the files.

All you have to do is run the following command to share the files:

$ curl --upload-file Amazon_s3_tutorial.pdf

Here, Amazon_s3_tutorial.pdf is the file in my Home folder.

Sample output:

When the upload is completed, the service returns the unique download link of the file. You can pass this URL to anyone who wants to download and use this file.

It is also possible to upload files using ‘wget’.

$ wget --method PUT --body-file=/home/sk/file.pdf -O - -nv allows us to upload multiple files in one go.

To upload multiple files at once, run:

$ curl -i -F [email protected]/home/sk/Downloads/bash_tips.pdf -F [email protected]/home/sk/Downloads/Docker.pdf

Sample output:

Alternatively, you can preview and download it from your Web browser. Just place the download link on the address bar of your web browser and click the download button to download the shared file.

Encrypt and upload files allows you to encrypt and upload the files.

To encrypt and upload file, run:

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

You’ll be asked to enter a passphrase twice. Then, will give you the download link of the encrypted file.

Decrypt and download files

To decrypt and download the above encrypted file, run:

$ curl|gpg -o- > /home/sk/ostechnix.txt

Sample output:

% Total % Received % Xferd Average Speed Time Time Time Current
 Dload Upload Total Spent Left Speed

Add alias

If you plan to frequently use this service, you can add alias to .bashrc or .zshrc files to make this command even more easier.

If you use BASH shell, edit ~/.bashrc file:

$ sudo vi ~/.bashrc

Add the following lines at the end.

transfer() { if [ $# -eq 0 ]; then echo -e "No arguments specified. Usage:\necho transfer /tmp/\ncat /tmp/ | transfer"; return 1; fi 
tmpfile=$( mktemp -t transferXXX ); if tty -s; then basefile=$(basename "$1" | sed -e 's/[^a-zA-Z0-9._-]/-/g'); curl --progress-bar --upload-file "$1" "$basefile" >> $tmpfile; else curl --progress-bar --upload-file "-" "$1" >> $tmpfile ; fi; cat $tmpfile; rm -f $tmpfile; }

Save and close the file. Then, run the following command to take effect the saved changes.

$ source ~/.bashrc

Now, you can upload and download files as shown below.

$ transfer file.txt

Sample output:

I must admit that I really liked I haven’t seen or used this kind of file sharing tools before. As far as I tested this tool, it is really easy and very fast. And yes, some of the popular web services such as Google Drive, One Drive also allows you to share and transfer files over Internet. But they have some limitations. You need to have a registered account to use those services. But, doesn’t need any registered account. And, it’s really easy and fast to share large files. More importantly, you don’t need to leave your Terminal and don’t need to install any extra applications to share the files.
