       pegasus-transfer - Handles data transfers in Pegasus workflows.


       pegasus-transfer [-h]
                          [--file inputfile]
                          [--threads number_threads]
                          [--max-attempts attempts]


       pegasus-transfer takes a list of url pairs, either on stdin or with an input file,
       determines the correct tool to use for the transfer and executes the transfer. Some of the
       protocols pegasus-transfer can handle are GridFTP, SRM, Amazon S3, HTTP, and local
       cp/symlinking. Failed transfers are retried.

       Note that pegasus-transfer is a tool mostly used internally in Pegasus workflows, but the
       tool can be used stand alone as well.


       -h, --help

       -f inputfile, --file inputfile
           File with input pairs. If not given, stdin will be used.

       -m, --max-attempts attempts
           Maximum number of attempts for retrying failed transfers.

       -t, --threads number_threads
           The number of threads to use. This controls the parallelism of transfers.

       -d, --debug
           Enables debugging output.


           $ pegasus-transfer
           # src 1 local_site
           # dst 1 local_site


       Credentials used for transfers can be specified with a combination of comments in the
       input file format and environment variables. For example, give the following input file:

           # src 1 isi
           # dst 1 tacc_stampede

       pegasus-transfer will expect either one environment variable specifying one credential to
       be used on both end of the connection (X509_USER_PROXY), or two separate environment
       variables specifying two different credentials to be used on the two ends of the
       connection. The the latter case, the environment variables are derived from the site names
       provided in the input file commments. In the example above, the environment variables
       would be named X509_USER_PROXY_isi and X509_USER_PROXY_tacc_stampede


       In order to speed up data transfers, pegasus-transfer will start a set of transfers in
       parallel using threads. Threads are turned off when retrying failed transfers.
