[`transfer.sh`](https://transfer.sh) is an easy to use file sharing service from the command line
## Usage
To use it, add `transfer` to the plugins array in your zshrc file:
Add `transfer` to your plugins array in your zshrc file:
```zsh
plugins=(... transfer)
```
Then you can:
## Usage
- transfer a file:
- Transfer a file: `transfer file.txt`.
```zsh
transfer file.txt
```
- Transfer a whole directory (it will be automatically compressed): `transfer dir`.
- transfer a whole directory (it will be automatically compressed):
### Encryption / Decryption
```zsh
transfer directory/
```
- Encrypt and upload a file with symmetric cipher and create ASCII armored output:
```zsh
transfer file -ca
```
- Encrypt and upload directory with symmetric cipher and gpg output:
```zsh
transfer directory -ca
```
- Decrypt file:
```zsh
gpg -d file -ca
```
- Decrypt directory:
```zsh
gpg -d your_archive.tgz.gpg | tar xz
```
