Applications
The release contains a full xrootd releases and a few other tools. The applications of interest are:
| name | Description |
|---|---|
| xrdcp | transfer files from and to xrootd |
| xrdls | list directory on all the xrootd servers |
| xrdprel | run a program under the xrootd preload library (useful for reading fits files) |
| xrd.pl | command line tool to issue commands to xrootd like, stat a file, checksum a file,... |
One think to notice about all the applications is that they are links to a wrapper script. The wrapper script sets the proper environment so that the xrootd authorization libs are found and then runs the proper executable.
Location of the Xrootd Client tools
The glast xrootd client tools are available in the xrootd afs application area:
/afs/slac.stanford.edu/g/glast/applications/xrootd/<RELEASE>
Where <RELEASE> is one of the following names:
| RELEASE | Comment |
|---|---|
| PROD | production version. Updates will be announced and require a CCB |
| DEV | development version. Updates will not be announced, but this release has been tested |
| TEST | experimental version which might not always be working |
| FITS | test release to read fits files from xrootd. (Will disapear at some moment) |
Each of the release contains a bin directory for the executables and a lib for the xrootd libraries.
No environment variables have to be set as the application do this by them self. For example to copy a file from xrootd one would run the command:
/afs/slac/g/glast/applications/xrootd/PROD/bin/xrdcp root://glast-rdr/... localfile
Using applications from a different location, e.g.: /usr/local/bin/xrdcp, will most likely not work as they are not able to load the xrootd security libraries.
