Shell completion

The Polkadot cli command supports shell auto-completion. For this to work, you will need to run the completion script matching you build and system.

Assuming you built a release version using cargo build --release and use bash run the following:

source target/release/completion-scripts/polkadot.bash

You can find completion scripts for:

• bash
• fish
• zsh
• elvish
• powershell

To make this change persistent, you can proceed as follow:

First install

COMPL_DIR=$HOME/.completion
mkdir -p $COMPL_DIR
cp -f target/release/completion-scripts/polkadot.bash $COMPL_DIR/
echo "source $COMPL_DIR/polkadot.bash" >> $HOME/.bash_profile
source $HOME/.bash_profile

Update

When you build a new version of Polkadot, the following will ensure you auto-completion script matches the current binary:

COMPL_DIR=$HOME/.completion
mkdir -p $COMPL_DIR
cp -f target/release/completion-scripts/polkadot.bash $COMPL_DIR/
source $HOME/.bash_profile
