[`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
|
||||
```
