Image of a disc changer

dich

dich (pronounced "ditch") stands for DIsc CHanger, a profile/configuration file manager. Switch between your profiles as if you are using a good-ol' CD changer.

dich was written when I was binge-downloading data from the Corpenius Data Store. Its API uses a profile file for each account, and I needed to switch between them frequently. It should be useful for similar uses.

First time setup

Clone this repository in a favorable location.

Before running, edit the config.json file and the CONFIG_FILE variable in dich.sh based on your needs.

Important: Use absolute paths for CONFIG_FILE in dich.sh, and directory and target in config.json if you intend to run it from elsewhere.

You might also want to add execute permission, create a link of dich and add to PATH variable by:

chmod u+x dich.sh
ln -s dich.sh dich
export PATH=`pwd`:$PATH

Use dich -i to initialize first before running other modes.

Usage

dich has four primary modes: init -i, get -g,next -n, and set -s. The modes are pretty much self-explanatory.

  • Use dich -i to initialize first before running other modes.

After this, you can edit the list of candidate files config.json manually, or dich -i again if there are changes.

  • -g would output the current state that the target file is in.

  • Use -n flag to update the target file to the next file in the candidate file list, or use -s to interactively specify a file to overwrite to the target.

  • Use -h flag for a brief help message.
