### Restore
### Restore (not implemented yet)
This will allow you to restore a file on disk to the specific version that is stored in the bucket.
### Get
The utility will allow you to get the contents of a backup up file and have it output to the terminal.
### Delete
The utility allows you to delete entries/backups in the bucket if you choose to do so.

Description:
This utlity is meant to be used to interact with & manage the filebucket in the same capacity as
the builtin filebucket utility. However, it does not handle any puppet tie ins.
This utlity is meant to be used to interact with & manage the filebucket on P4 nodes due to the
utility for that `puppet filebucket -l <action>` being nonfunctional.
I created this due to the puppet filebucket utility in my companies P4 envrionments not
functioning
This implements the same functionality (minus the puppet tie-in) and will allow the user to
search the filebucket and restore from it.
Actions:
search <term> : Search for bucket entries matching a portion of the filepath
list : List all Bucket entries
list-files : List all files/paths that have been backed up to the bucket
get <entry-hash> : Get the content of a specific entry (by hash)
restore <value> : Restore previous state of file stored in bucket. Value can be hash or filename/filepath
: Note: To restore to an alternate path you will need to provide the path via the -o flag
:
backup <file> : Backup the file to the bucket
delete <hash> : Delete the entry from the bucket
Restore Flags:
-o | --output-file <file> : Used to provide an alternate restoral path for the restore function
search <term> : Search for bucket entries matching a portion of the filepath
list : List all Bucket entries
list-files : List all files/paths that have been backed up to the bucket
get <entry-hash> : Get the content of a specific entry (by hash)
Global Flags:
-d | --debug : Set debug flag
-h | --help : This help message
-b | --bucket <bucket-dir> : User specified bucket directory
Listing Filter Flags:
--from-date <DATE> : Filter listings from starting after this point (FORMAT: YYYY-MM-DD HH:MM:SS)
: EX:
: 1. --from-date 2023-05-10
: 2. --from-date "2023-05-10 13:23"
:
--to-date <DATE> : Filter listings from ending at this point (FORMAT: YYYY-MM-DD HH:MM:SS)
: EX:
: 1. --to-date 2024-05-10
: 2. --to-date "2024-05-10 05:27"
:
Info Format Flags:
-i | --inline : Set the info format to inline (MTIME : HASH : FILENAME)
-l | --long : Set the info format to long
: Entry [HASH]:
: Paths: path1,path2,...,pathn
: MTIME: YYYY-MM-DD HH:MM:SS -####
:
-c | --csv : Set the info format to csv ( MTIME,HASH,FILENAME1[;FILENAMEn] )
-d | --debug : Set debug flag
-h | --help : This help message
