Remove unreferenced chunks from a store

## NAME

desync-prune - Remove unreferenced chunks from a store

## SYNOPSIS

**desync prune \<index\> \[\<index\>...\] \[flags\]**

## DESCRIPTION

Read chunk IDs from index files and delete all chunks from a store that are not referenced in any of the provided index files. This is a destructive operation; a confirmation prompt is shown before any chunks are deleted unless --yes is used. Use '-' to read a single index from STDIN.

**--client-key**=""\
 	path to client key for TLS authentication

**-n**, **--concurrency**=10\
 	number of concurrent goroutines, -1 to let desync choose: the number of CPUs for chunking and hashing, adapting to each store up to 128 for transfers

**-e**, **--error-retry**=3\
 	number of times to retry in case of network error

**-b**, **--error-retry-base-interval**=500ms\
 	initial retry delay, increases linearly with each subsequent attempt

**-h**, **--help**\[=false\]\
 	help for prune

**-s**, **--store**=""\

**-t**, **--trust-insecure**\[=false\]\
