Project description
COMDIRAC
Package to supply a comprehensive list of UNIX-like commands for the DIRAC user interface
Provided commands can serve several purposes:
User Client Configuration
Users can customize their client behaviour. The configuration file lies in $HOME/.dirac/dcommands.conf.
This file is a ConfigParser formatted file (see: http://docs.python.org/2/library/configparser.html).
Here is a sample configuration file:
# dcommands.conf
# global client configuration (mainly default profile) [global] default_profile = frangrilles_user
# frangrilles_user profile [frangrilles_user] # DIRAC group name for this profile group_name = frangrilles_user # Home directory home_dir = /vo.france-grilles.fr/user/p/pgay # default destination for commanddput default_se = M3PEC-disk # default options for command drepl replication_scheme = all() replication_ses = LAL-disk,CPPM-disk,MSFG-disk
# other profile [dirac_user] home_dir = / group_name = dirac_user
It contains a [global] section and some named profile sections. Profiles sections are used by dinit command to configure session with some user profile.
commands:
dconfig - get and set configuration options from configuration file
Session Environment Commands
COMDIRAC sessions are built from a user profile (see User client configuration).
Sessions are used by all commands to remember client state (think of shell environment variables)
Each session is applicable to the Unix process calling the COMDIRAC command.
commands:
dinit - initialize a session from a profile (with proxy creation)
dgetenv - get session environment options
dsetenv - set session environment options
dunsetenv - delete session environment options
File Catalog Files And Directories
These commands, like others in COMDIRAC, require LFN path arguments for files and directories. These LFN paths are specified without any prefix (no “lfn:”).
The main feature of these commands is to provide a sort of File Catalog “working directory” within user session. This working directory can be set and printed with dcd and dpwd, respectively. When correctly set, working directory allows user to name LFNs using relative paths.
commands:
dpwd - print File Catalog working directory
dcd - change File Catalog working directory
dls - list File Catalog files and directories
dreplicas - liste File Catalog file replicas
dmkdir - create File Catalog directory
drmdir - delete File Catalog directory
Data Management
These commands, like others in COMDIRAC, require LFN path arguments for files and directories. These LFN paths are specified without any prefix (no “lfn:”).
When a local path is needed, as with dget or dput, it is deduced from command context. For example, local path is last argument with command dget, while it is first with dput.
commands:
dput - register local file in the File Catalog (and copies replica to a Storage Element)
dget - retrieves a local copy of a File Catalog file
drm - remove a file from the File Catalog (and all associated replicas)
drepl - replicates a File Catalog file
dchmod - change access rights of a File Catalog file
File Catalog Metadata Management
commands: * dmeta - manipulates File Catalog metadata * dfind - find files with File Catalog metadata
Jobs Management
commands:
dinput - retrieve input sandbox for a DIRAC job
dkill - kill or delete DIRAC job
dlogging - retrieve logging information for a DIRAC job
doutput - retrieve output sandbox for a DIRAC job
dstat - retrieve status of DIRAC jobs
dsub - submit jobs to DIRAC WMS
