A command line download/upload tool with resume.

Table of Contents

❓ Why

Simplicity: download or upload files depending on parameter order with default settings.

💿︎ Installation

Download a release for Linux or MacOS from releases. See the Docker section on how to run it platform-independently.

If you want to build from source, use: bash cargo install aim

💡 Features

Feature matrix

Protocol | Download | Upload | Resume | Interactive mode | ----------|----------|--------|--------|------------------| http(s) | ✅ | ✅ | ✅ | ✅ | ftp | ✅ | ✅ | ✅ | ❌ | sftp | ✅ | ✅ | ✅ | ❌ | ssh | ✅ | ✅ | ❌ | ❌ | s3 | ✅ | ✅ | ❌ | ❌ |

Download / Upload

• default action implied from parameter order.
  • aim https://domain.com/ -> Display contents.
  • aim https://domain.com/source.file . -> Download.
  • aim source.file https://domain.com/destination.file -> Upload.
• support for http(s), (s)ftp, ssh, s3 (no resume at the moment).

Optional check of sha256

To validate that a download matches a desired checksum, just list it at the end when invoking aim. rust aim https://github.com/XAMPPRocky/tokei/releases/download/v12.0.4/tokei-x86_64-unknown-linux-gnu.tar.gz . 0e0f0d7139c8c7e3ff20cb243e94bc5993517d88e8be8d59129730607d5c631b

Resume

If you're hosting a http(s) server yourself, upload needs PUT ranges (or a patched version of nginx).

Interactive mode

This feature can be activated by passing the -i or --interactive flag to the invocation.

It allows you to specify an initial URL and then navigate through links found in it using fuzzy search.

Controls: * Start typing, partial matches are listed. * Tab expands the path and goes into it, lists contents. * / goes into path without expanding, lists contents. * .. goes one level up. * Enter finalizes the interaction and takes the result, performs the required operation on it.

This feature can be used in conjunction with Output during downloading and/or Sharing a folder.

Output during downloading

Several output formats can be specified: * aim source . - downloads to the same basename as the source. * aim source + - downloads to the same basename as the source and attempts to decompress. Target extensions are read and the system decompressor is called. Further info here. * aim source destination - download to a new or existing file called destination.

Sharing a folder

aim can serve a folder over http on one device so that you can download it on another. By default, the serving port is 8080 or the next free port.

Machine A bash aim . # to serve current folder

Machine B bash aim http://ip_of_Machine_A:8080 # list contents aim http://ip_of_Machine_A:8080/file . # download

Moreover, since hosting is done over http, the client can even be a browser:

The server prints logs to the standard output. To colorize them, you can use pipecolor with the provided .pipecolor.aim.toml in this repo:

bash aim /tmp | pipecolor -c ~/.pipecolor.aim.toml

Indicators

By default, a progressbar is displayed when up/downloading. The indicators can be configured via the internally used indicatif package.

You can change the display template and progress chars by either setting correct environment variables or creating a .env file in the folder you are calling from: bash AIM_PROGRESSBAR_DOWNLOADED_MESSAGE="🎯 Downloaded {input} to {output}" AIM_PROGRESSBAR_MESSAGE_FORMAT="🎯 Transfering {url}" AIM_PROGRESSBAR_PROGRESS_CHARS="=>-" AIM_PROGRESSBAR_TEMPLATE="{msg}\n{spinner:.cyan} {elapsed_precise} ▕{bar:.white}▏ {bytes}/{total_bytes} {bytes_per_sec} ETA {eta}." AIM_PROGRESSBAR_UPLOADED_MESSAGE="🎯 Uploaded {input} to {output}"

By default, no progressbar is displayed if content length <1MB (easy display contents of remote).

Output

Because default output is stdout, aim is pipe-able to other commands: bash aim https://github.com/XAMPPRocky/tokei/releases/download/v12.0.4/tokei-x86_64-unknown-linux-gnu.tar.gz | tar xvz aim https://www.rust-lang.org/ | htmlq --attribute href a

🔑 Authentication

Basicauth in url

Just use the syntax protocol://user:pass@server:port. This can be used for all http(s), ftp, ssh and s3.

Example for downloading:

bash aim ftp://user:pass@127.0.0.1:21/myfile .

Netrc

Create a file named .netrc with read permissions in ~ or the current folder you're running aim from to automate login to that endpoint: bash machine mydomain.com login myuser password mypass port server_port

SSH keys

Keys that match the following patterns are automatically tried: * ided25519 * idrsa * keys/ided25519 * keys/idrsa * ~/.ssh/idrsa * ~/.ssh/keys/ided25519

.aws folder

Credentials for AWS interaction (i.e.: S3) are automatically read from ~/.aws/credentials.

Alternatively, the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables are read.

🆕 Updating

aim can self update in-place using:

bash aim --update

🐳 Docker

For convenience, alpine-based docker images for aarch64 and x64 are available, so arguments can be passed directly to them.

bash docker run --rm -it -v $(pwd):/src --user $UID:$UID mihaigalos/aim https://raw.githubusercontent.com/mihaigalos/aim/main/LICENSE.md

Hosting on machine A

bash cd $(mktemp -d) echo hello > myfile docker run --rm -it -v $(pwd):/src --user $UID:$UID -p 8080:8080 mihaigalos/aim /src

Downloading on machine B

Adapt IP to match that of machine A.

```bash docker run --rm -it -v $(pwd):/src --user $UID:$UID mihaigalos/aim http://192.168.0.24:8080/myfile /src/myfile

```
