## About TermSCP 🖥

TermSCP is basically a porting of WinSCP to terminal. So basically is a terminal utility with an TUI to connect to a remote server to retrieve and upload files and to interact with the local file system. It works both on **Linux**, **MacOS**, **BSD** and **Windows** and supports SFTP, SCP, FTP and FTPS.

---

### Why TermSCP 🤔

It happens quite often to me, when using SCP at work to forget the path of a file on a remote machine, which forces me then to connect through SSH, gather the file path and finally download it through SCP. I could use WinSCP, but I use Linux and I pratically use the terminal for everything, so I wanted something like WinSCP on my terminal. Yeah, I know there is midnight commander too, but actually I don't like it very much tbh (and hasn't a decent support for scp).

## Features 🎁

- Different communication protocols
  - SFTP
  - SCP
  - FTP and FTPS
- Practical user interface to explore and operate on the remote and on the local machine file system
- Bookmarks and recent connections can be saved to access quickly to your favourite hosts
- Supports text editors to view and edit text files
- Supports both SFTP/SCP authentication through SSH keys and username/password
- User customization directly from the user interface
- Compatible with Windows, Linux, BSD and MacOS
- Written in Rust
- Easy to extend with new file transfers protocols

## Usage ❓

TermSCP can be started with the following options:

- `-P, --password <password>` if address is provided, password will be this argument
- `-v, --version` Print version info
- `-h, --help` Print help page

TermSCP can be started in two different mode, if no extra arguments is provided, TermSCP will show the authentication form, where the user will be able to provide the parameters required to connect to the remote peer.

Alternatively, the user can provide an address as argument to skip the authentication form and starting directly the connection to the remote server.

### Address argument 🌎

The address argument has the following syntax:

```txt
[protocol]://[username@]<address>[:port]
```

Let's see some example of this particular syntax, since it's very comfortable and you'll probably going to use this instead of the other one...

- Connect using default protocol (*defined in configuration*) to 192.168.1.31, port is default for this protocol (22); username is current user's name

    ```sh
    termscp 192.168.1.31
    ```

- Connect using default protocol (*defined in configuration*) to 192.168.1.31, port is default for this protocol (22); username is `root`

    ```sh
    termscp root@192.168.1.31
    ```

- Connect using scp to 192.168.1.31, port is 4022; username is `omar`

    ```sh
    termscp scp://omar@192.168.1.31:4022
    ```

#### How Password can be provided 🔐

You have probably noticed, that, when providing the address as argument, there's no way to provide the password.
Password can be basically provided through 3 ways when address argument is provided:

- `-P, --password` option: just use this CLI option providing the password. I strongly unrecommend this method, since it's very unsecure (since you might keep the password in the shell history)
- Via `sshpass`: you can provide password via `sshpass`, e.g. `sshpass -f ~/.ssh/topsecret.key termscp cvisintin@192.168.1.31`
- You will be prompted for it: if you don't use any of the previous methods, you will be prompted for the password, as happens with the more classics tools such as `scp`, `ssh`, etc.

## Bookmarks ⭐

In TermSCP it is possible to save favourites hosts, which can be then loaded quickly from the main layout of termscp.
TermSCP will also save the last 16 hosts you connected to.
This feature allows you to load all the parameters required to connect to a certain remote, simply selecting the bookmark in the tab under the authentication form.

Bookmarks will be saved, if possible at:

- `$HOME/.config/termscp/` on Linux/BSD
- `$HOME/Library/Application Support/termscp` on MacOs
- `FOLDERID_RoamingAppData\termscp\` on Windows

For bookmarks only (this won't apply to recent hosts) it is also possible to save the password used to authenticate. The password is not saved by default and must be specified through the prompt when saving a new Bookmark.

> I was very undecided about storing passwords in termscp. The reason? Saving a password on your computer might give access to a hacker to any server you've registered. But I must admit by myself that for many machines typing the password everytime is really boring, also many times I have to work with machines in LAN, which wouldn't provide any advantage to an attacker, So I came out with a good compromise for passwords.

I warmly suggest you to follow these guidelines in order to decide whether you should or you shouldn't save passwords:

- **DON'T** save passwords for machines which are exposed on the internet, save passwords only for machines in LAN
- Make sure your machine is protected by attackers. If possible encrypt your disk and don't leave your PC unlocked while you're away.
- Preferably, save passwords only when a compromising of the target machine wouldn't be a problem.

To create a bookmark, just fulfill the authentication form and then input `CTRL+S`; you'll then be asked to give a name to your bookmark, and tadah, the bookmark has been created.
If you go to [gallery](#gallery-), there is a GIF showing how bookmarks work 💪.

### Are my passwords Safe 😈

Well, kinda.
As said before, bookmarks are saved in your configuration directory along with passwords. Passwords are obviously not plain text, they are encrypted with **AES-128**. Does this make them safe? Well, no, the key used to encrypt your passwords is generated at the first launch of termscp and stored on your drive. So it's still possible to retrieve the key to decrypt passwords. Luckily, the location of the key guarantees your key can't be read by users different from yours, but yeah, I still wouldn't save the password for a server exposed on the internet 😉.

## Text Editor ✏

TermSCP has, as you might have noticed, many features, one of these is the possibility to view and edit text file. It doesn't matter if the file is located on the local host or on the remote host, termscp provides the possibility to open a file in your favourite text editor.
In case the file is located on remote host, the file will be first downloaded into your temporary file directory and then, **only** if changes were made to the file, re-uploaded to the remote host. TermSCP checks if you made changes to the file verifying the last modification time of the file.

Just a reminder: **you can edit only textual file**; binary files are not supported.

### How do I configure the text editor 🦥

Text editor is automatically found using this [awesome crate](https://github.com/milkey-mouse/edit), if you want to change the text editor to use, change it in termscp configuration. [View more](#configuration-️)

---

## Configuration ⚙️

TermSCP supports some user defined parameters, which can be defined in the configuration.
Underhood termscp has a TOML file and some other directories where all the parameters will be saved, but don't worry, you won't touch any of these files, since I made possible to configure termscp from its user interface entirely.

termscp, like for bookmarks, just requires to have these paths accessible:

- `$HOME/.config/termscp/` on Linux/BSD
- `$HOME/Library/Application Support/termscp` on MacOs
- `FOLDERID_RoamingAppData\termscp\` on Windows

To access configuration, you just have to press `<CTRL+C>` from the home of termscp.

These parameters can be changed:

- **Default Protocol**: the default protocol is the default value for the file transfer protocol to be used in termscp. This applies for the login page and for the address CLI argument.
- **Text Editor**: the text editor to use. By default termscp will find the default editor for you; with this option you can force an editor to be used (e.g. `vim`). **Also GUI editors are supported**, unless they `nohup` from the parent process so if you ask: yes, you can use `notepad.exe`, and no: **Visual Studio Code doesn't work**.

### SSH Key Storage 🔐

Along with configuration, termscp provides also an **essential** feature for **SFTP/SCP clients**: the SSH key storage.

You can access the SSH key storage, from configuration moving to the `SSH Keys` tab, once there you can:

- **Add a new key**: just press `<CTRL+N>` and you will be prompted to create a new key. Provide the hostname/ip address and the username associated to the key and finally a text editor will open up: paste the **PRIVATE** ssh key into the text editor, save and quit.
- **Remove an existing key**: just press `<DEL>` or `<CTRL+E>` on the key you want to remove, to delete persistently the key from termscp.
- **Edit an existing key**: just press `<ENTER>` on the key you want to edit, to change the private key.

> Q: Wait, my private key is protected with password, can I use it?
> A: Of course you can. The password provided for authentication in termscp, is valid both for username/password authentication and for RSA key authentication.

## Known issues 🧻

- Ftp:
  - Time in explorer is `1 Jan 1970`, but shouldn't be: that's because chrono can't parse date in a different locale. So if your server has a locale different from the one on your machine, it won't be able to parse the date.
  - Some servers don't work: yes, some kind of ftp server don't work correctly, sometimes it won't display any files in the directories, some other times uploading files will fail. Up to date, `vsftpd` is the only one server which I saw working correctly with TermSCP. Am I going to solve this? I'd like to, but it's not my fault at all. The library used for FTP, which is [rust-ftp](https://github.com/mattnenterprise/rust-ftp) has been abandoned for 2 years and only in december 2020, the maintainer is back to work. I hope this issue will be solved soon.
- `NoSuchFileOrDirectory` on connect: let me guess, you're running on WSL and you've installed termscp through cargo. I know about this issue and it's a glitch of WSL I guess. Don't worry about it, just move the termscp executable into another PATH location, such as `/usr/bin`, or install it through the appropriate package format (e.g. deb).

## Upcoming Features 🧪

- **Find command in explorer**: possibility to search for files in explorers.
