The Command Line BIC permits you to execute a script at the operating system command line or shell, and provides the ability to execute commands on the system where the BIC's associated BIC Manager resides. When implementing the Command Line BIC to modify a work item's hash table, you must specify the script file (which must already exist) and the hash table keys of work item to be used. The hash table is not updated directly when the Command Line BIC executes a script, but rather the script must produce a file that can then be loaded with the Work Item Import/Export BIC, at which point the work item's hash table is modified. See Work Item Import/Export BIC Format Options for additional information.
