h2. Synopsys

<pre>

ciop-copy  [-h] [-a] [-q] [-f] [-b <url-base>] [-d <driver-def>] 

      [-o|O <sink-dir>] [-w <work-dir>] [-c] [-p <prefix>] [-z|-Z]

      [-r <num-retries>] [-t <timeout>] [-R] [-l <log-label>] [-D]

      <url1> [<url2> ... <urlN>]

</pre>

URL Parameters:

> Arguments are URL strings provided by seurl

> if a parameter is specified as '-', URLs are read and inserted from standard input

h2. Description 

The following options are available:

> -h displays this help page

> -a               abort on first error without attempting to process further URLs

> -q               quiet mode, local filenames are not echoed to stdout after transfer

> -f               force transfer of a physical copy of the file for nfs and HDFS urls.

> -d <driver-file> get additional drivers from shell file <driver-file>. Drivers shall contain a named <protocol>Driver

> -o|O <out-dir>   defines the output directory for transfers (default is /root) with -O the sink files or directories possibly existing in the output directory will be overwritten.

> -co <out-dir>    same as -c -o <out-dir>. Kept for retro-compatibility.

> -c               creates the output directory if it does not exist

> -p <prefix>      prepend the given prefix to all output names

> -z               provide output as a compressed package (.gz for files or .tgz for folders). NOTE that it will not compress already compressed files (.gz, .tgz or .zip)

> -U|--no-uzip     disable file automatic decompression of .gz, .tgz and .zip files.

> -r <num-retries> defines the maximum number of retries (default is 5)

> -rt <seconds>    define the time (in seconds) between retries (default is 60)

> -t <timeout>     defines the timer (in seconds) for the watchdog timeout applicable to gridftp, scp, ftp, http, and https schemes (default is 600 seconds)

> -R               do not retry transfer after timeout

> -D               set debug mode for command output parsing debugging

> -H               do not follow html and rdf tags and .uar archives.

> -s               skip download if sink path already exists

> -x <pattern>     exclude the files matching the pattern

> -w               do not overwrite single files iif already exist

h2. Output

unless the quiet option is used (-q), the local path of each file (or directory) downloaded after each URL transfer is echoed, one per line unless the -U option is used, if the output file is a .gz or .tgz file it will be decompressed

unless the -H options is specified, the software will follow the RDF <dclite4g:onlineResource> and the HTML href and refresh tags.

h2. Exit status

> 0      all URLs were successfully downloaded

> 1      an error occured during processing

> 255    environment is invalid (e.g. invalid working directory) or invalid options are provided

> 254    output directory does not exist or failed creating it (with -c option)

> if the -a option is used, the exit code is set to the error code of the last URL transfer:

> > 252    no driver available for URL

> > 251    an existing file or directory conflicts with the sink for the URL in the output directory

> > 250    an error occured while unpacking the output file or when packaging/compressing the output file (when -z or -Z option is used)

> > 128    a timeout occured while fetching an url

> > 127    a fatal error occured, source of error is not known or not handled by driver

> > <128   error codes specific to the transfer scheme

> > 1      resource pointed by input URL does not exist
