File and Replica Manipulation with LCG utilities
LCG commands are the simplest and most effective way to transfer files onto and out of the grid as well as manipulate the files when they are present on the grid. The hide much of the complexity of data management from the end user, which is a good thing!
Note that when interacting with file catalogs the definition of LCG_CATALOG_TYPE is important.
Replica Management
| lcg-cp | Copies a Grid file to a local destination (download). | |
| lcg-cr | Copies a file to a SE and registers the file in the catalog (LFC or LRC) (upload). | |
| lcg-del | Deletes one file (either one replica or all replicas). | |
| lcg-rep | Copies a file from one SE to another SE and registers it in the catalog (LFC or LRC) (replicate). | |
| lcg-gt | Gets the TURL for a given SURL and transfer protocol. | |
| lcg-sd | Sets file status to "Done" for a given SURL in an SRM's request. |
File Catalog Interaction
| lcg-aa | Adds an alias in the catalog (LFC or RMC) for a given GUID. | |
| lcg-ra | Removes an alias in the catalog (LFC or RMC) for a given GUID. | |
| lcg-rf | Registers in the the catalog (LFC or LRC/RMC), a file residing on an SE. | |
| lcg-uf | Unregisters in the the catalog (LFC or LRC) a file residing on an SE. | |
| lcg-la | Lists the aliases for a given LFN, GUID or SURL. | |
| lcg-lg | Gets the GUID for a given LFN or SURL. | |
| lcg-lr | Lists the replicas for a given LFN, GUID or SURL. |
Documentation
All of the LCG Util commands have unix man page documentation. For a discussion on how to use the commands see the LCG User Guide
