# oxpasta
|
||||
|
||||
A minimal shell script for interacting with a [rustypaste](https://github.com/orhun/rustypaste) server
|
||||
|
||||
## Brief
|
||||
|
||||
As someone who needed quick access to only a handful of features, [rpaste](https://github.com/orhun/rustypaste-cli) was overkill. As such, this shell only provides shortcuts for 3 features: upload, oneshot (-o), and url shortening (-s).
|
||||
|
||||
## Help
|
||||
|
||||
``` zsh
|
||||
Usage: oxpasta [OPTION] FILE
|
||||
|
||||
Options:
|
||||
[none] {file} Upload a file
|
||||
-o, --oneshot {file} Upload a file as a oneshot link
|
||||
-s, --shorten-url {url} Shorten a given URL
|
||||
-h, --help Display this help message
|
||||
|
||||
Description:
|
||||
minimal rustypaste cli script
|
||||
|
||||
Requires:
|
||||
export OXP_SERVER="https://example.com"
|
||||
|
||||
Examples:
|
||||
oxpasta /path/to/file
|
||||
| Uploads the file located at /path/to/file
|
||||
oxpasta -o /path/to/file
|
||||
| Uploads the oneshot URL https://example.com
|
||||
oxpasta -s https://example.com/long/url
|
||||
| Shortens the URL to https://<server>/<some-text>
|
||||
```
|
||||
|
||||
## Setup
|
||||
|
||||
1. save `oxpasta.sh` file
|
||||
|
||||
|
||||
1. symlink `oxpasta`
|
||||
``` zsh
|
||||
sudo ln -s /path/to/oxpasta.sh /usr/local/bin/oxpasta
|
||||
```
|
||||
|
||||
1. set server url
|
||||
``` zsh
|
||||
echo 'export OXP_SERVER="https://<rustypaste-server-url>"' >> ~/.bashrc
|
||||
source ~/.bashrc
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
``` zsh
|
||||
$ git clone https://github.com/rskntroot/oxpasta.git
|
||||
$ echo $PATH | grep -o '/usr/local/sbin'
|
||||
$ sudo ln -s /home/${USER}/workspace/oxpasta/oxpasta.sh /usr/local/bin/oxpasta
