··· 1 1 - # my-bash-scripts 2 2 - 3 3 - These are the basic bash scripts I've made for myself. They're made for macOS, so there's no guarantee they'll work on other OSes. 4 4 - 5 5 - # Install 6 6 - 7 7 - 1. Download the scripts and put them in whatever folder you want. In my case, they are in `~/dev/my-bash-scripts/bin`. 8 8 - 2. Now you need to make the scripts executable. You can do that by running `chmod +x <YOUR_FOLDER>/*`. 9 9 - 3. Lastly, add the folder to your PATH, so you can call the scripts by their filename in your terminal from anywhere. Edit the file named `.bash_profile` (or create it if it does not exist). Add the following line to it: `export PATH=<YOUR_FOLDER>:$PATH`. 10 10 - 11 11 - # Scripts 12 12 - 13 13 - ## welp 14 14 - Super simple script that lists the files in the same folder as the script is in. In other words, it lists the scripts here. 15 15 - 16 16 - ## chill 17 17 - Stops execution for a specified amount of time. Useful for scheduling stuff. `chill` shows the syntax: 18 18 - ``` 19 19 - Syntax: chill #h 20 20 - Syntax: chill #m 21 21 - Syntax: chill #h #m 22 22 - ``` 23 23 - 24 24 - ## d-c 25 25 - Basic wrapper around the `docker-compose` command (which you should have if you got Docker installed). The command works the same as `docker-compose`, except: 26 26 - - When running `d-c run`, it automatically adds the `--rm` argument 27 27 - - When running `d-c up`, it automatically runs `docker-compose down` afterwards. 28 28 - 29 29 - ## render 30 30 - This will render [After Effects](https://www.adobe.com/products/aftereffects.html) projects, assuming you have After Effects installed in `/Applications/Adobe After Effects CC 2019` (Specifically, the `aerender` file needs to be in there). Running `render` shows the syntax: 31 31 - ``` 32 32 - Usage: 33 33 - render <file> [file...] 34 34 - 35 35 - Options: 36 36 - file After Effects .aep file for After Effects' aerender to render. 37 37 - ``` 38 38 - It was made to be able to support multiple path arguments, as well as taking folders as path arguments to render every .aep file inside those folders, but I don't think that works. Might fix that someday if I need it. 39 39 - 40 40 - ## reset-permissions 41 41 - Resets permissions of a directory. You should probably know what you're doing before running this. 42 42 - 43 43 - Running `reset-permissions` shows the syntax: 44 44 - ``` 45 45 - reset-permissions 46 46 - usage: reset-permissions <username> <directory> 47 47 - ``` 48 48 - 49 49 - This is the command it will run: 50 50 - ``` 51 51 - sudo chmod -RN <DIRECTORY> && \ 52 52 - sudo chown -R <USERNAME> <DIRECTORY> && \ 53 53 - sudo chmod -R 755 <DIRECTORY> 54 54 - ``` 55 55 - 56 56 - ## sleepy 57 57 - Hibernates your computer. I usually run this after `render` or `chill`. 58 58 - 59 59 - ## to 60 60 - Requires [ImageMagick](https://imagemagick.org) for images and [FFmpeg](https://ffmpeg.org) for audio and video. I recommend installing them using [Brew](https://brew.sh) by running `brew install ffmpeg imagemagick`. 61 61 - 62 62 - Converts audio and video. Running `to` shows this help message: 63 63 - ``` 64 64 - Usage: 65 65 - to <format> [options] <file1> [file2...] 66 66 - 67 67 - Options: 68 68 - format Format to convert to. 69 69 - --formats List all supported formats. 70 70 - -v, --verbose If you love logs. 71 71 - -h, --help Show this help message. 72 72 - 73 73 - Video/audio formats support FFmpeg options (see $ ffmpeg -h). 74 74 - Image formats support ImageMagick options (see $ man magick). 75 75 - Long arguments must have quotes (like "-b:a 128k"). 76 76 - ``` 77 77 - 78 78 - ## to-gif 79 79 - Requires [ffmpeg](https://ffmpeg.org) (which I recommend installing using [Brew](https://brew.sh)). 1 1 + # to 80 2 81 81 - Converts videos into gifs. If you do this frequently I would probably use some app instead. 82 82 - 83 83 - Running `to-gif` shows the syntax: 84 84 - ``` 85 85 - Syntax: to-gif <file> [fps] [scale] [duration] [start_at] 86 86 - file: File to convert to gif. Required. 87 87 - fps: Defaults to 15. 88 88 - scale: GIF resolution. Defaults to 1. 89 89 - duration: How long the gif will be, in seconds. Defaults to 999999. 90 90 - start_at: Where the video starts, in seconds. Defaults to 0 91 91 - ``` 3 3 + Pretty simple bash script that converts audio, video and image files using FFmpeg and ImageMagick.
