prysmctl is a command-line utility for common and one-off Ethereum proof-of-stake tasks, like helping users with validator exits or withdrawals. Most
prysmctl commands require access to a fully synced beacon node.
Run via binaries
Binaries for the latest
prysmctl tool can be found on the latest prysm release page. Each binary is a unique version with its own set of features. New releases may include new features for
prysmctl that will need to be downloaded separately. The installed binaries will need to be renamed to
prysmctl to use the example below.
Some users will need to give permissions to the the downloaded binaries to be executable. Linux users can do this by right clicking the file, going to permissions, and clicking the
Allow executing file as program checkmark. This may be different for each operating system.
Example of running prysmctl by opening a terminal at the installed location after renaming.
The binaries can be run through a terminal directly and won't need installation. Please refer to the list commands section for additional information.
