Name

       condor_urlfetch fetch - configuration given a URL

Synopsis

       condor_urlfetch [-<daemon>] urllocal-url-cache-file

Description

       Depending  on  the command line arguments, condor_urlfetchsends the result of a query from the urlto both
       standard output and to a file specified by local-url-cache-file, or it sends the  contents  of  the  file
       specified by local-url-cache-fileto standard output.

       condor_urlfetchis  intended  to be used as the program to run when defining configuration, such as in the
       nonfunctional example:

       LOCAL_CONFIG_FILE = $(LIBEXEC)/condor_urlfetch  -$(SUBSYSTEM) \

        http://www.example.com/htcondor-baseconfig  local.config |

       The pipe character (| ) at the end of this definition of the location of a configuration file changes the
       use of the definition. It causes the command listed on the right hand side of this  assignment  statement
       to  be  invoked,  and  standard  output becomes the configuration. The value of  $(SUBSYSTEM) becomes the
       daemon that caused this configuration to be read. If  $(SUBSYSTEM) evaluates to  MASTER ,  then  the  URL
       query  always  occurs, and the result is sent to standard output as well as written to the file specified
       by argument local-url-cache-file. When  $(SUBSYSTEM) evaluates to a daemon other than  MASTER , then  the
       URL  query  only occurs if the file specified by local-url-cache-filedoes notexist. If the file specified
       by local-url-cache-filedoes exist, then the contents of this file is sent to standard output.

       Note that if the configuration kept at the URL  site  changes,  and  reconfiguration  is  requested,  the
       -<daemon>argument  needs to be  -MASTER . This is the only way to guarantee that there will be a query of
       the changed URL contents, such that they will make their way into the configuration.

Options

       -<daemon>

          The upper case name of the daemon issuing the request for the configuration output. If  -MASTER , then
          the URL query always occurs. If a daemon other than  -MASTER , for example  STARTD or  SCHEDD  ,  then
          the URL query only occurs if the file defined by local-url-cache-filedoes not exist.

Exit Status

       condor_urlfetchwill exit with a status value of 0 (zero) upon success and non zero otherwise.
