gfal-sum  Calculates  the  checksum  of  the  specified  file,  using a specified checksum algorithm. The
       supported algorithm depend on the protocol and endpoint. Some examples are ADLER32 , CRC32 and MD5

gfal-sum
              srm://endpoint.cern.ch/path/file ADLER32

/etc/gfal2.d/*
              All configuration files in this directory affect the behavior of the underlying gfal2.

-h,--help
              show help about the command.

       -V,--version
              output version information and exit.

       -v,--verbose
              verbose mode. Repeat up to 3 times for the most verbose mode.

       -D,--definitionDEFINITION
              define properties for gfal2. Definitions have the following syntax: "CONFIG_GROUP:KEY=VALUE"

       -t,--timeoutTIMEOUT
              global timeout for the execution of the command. Command is interrupted if time expires before  it
              finishes. Note: A grace period of 30 seconds is given to the global timeout.

       -E,--certCERT
              user  certificate.  (This  option takes effect only after X509_USER_PROXY environment variable and
              default /tmp/x509up_u`id -u` location cannot provide a certificate)

       --keyKEY
              user private key.

       -4     forces Gfal2 to use IPv4 addresses only. (Option valid only for GridFTP protocol)

       -6     forces Gfal2 to use IPv6 addresses only. (Option valid only for GridFTP protocol)

       -C,--client-infoCLIENT_INFO
              provide custom client-side information.

       --log-fileLOG_FILE
              write Gfal2 library logs to the given file location.
