NAME

edg-gridftp-exists - Determine if file/directory exists on GridFTP server.

SYNOPSIS

edg-gridftp-exists [--proxy=proxy] [--timeout=timeout] [--noauth] URL [URL ...]

edg-gridftp-exists --usage

edg-gridftp-exists --help

DESCRIPTION

edg-gridftp-exists determines if the file or directory associated with the given URL exists. This command will return a status of 0 if the file or directory exists. In all other cases, it will return a non-zero value and print an error message to the standard error.

If more than one URL is given, then a successful return will only occur if all of the URLs exist. The processing will stop with the first failure.

OPTIONS

--proxy=proxy

Set the proxy to use for the GridFTP operation. If this is unset, then the underlying GridFTP library will try to find the proxy in the usual locations. This is useful if the proxy is in a non-standard location, or the caller is a daemon which must act on the behalf of a user.

--timeout=timeout

Set the overall time (in seconds) within which all the checks must complete. If no timeout is specified a default 120 second timeout will be used. A negative or zero timeout will report a timeout error before attempting to contact any of the FTP servers.

--noauth

If this flag is set, then the authentication of the data channel will be turned off. It is on by default.

--usage

Short description of the usage of this command is given.

--help

A description of the usage of this command and information on all of the options is given.

URL

URLs of the following formats are accepted:

ftp://ftp.server.org//absolute/file/name gsiftp://gridftp.server.org/~/home/relative/name.txt gridftp://gridftp.server.org/home/relative/name.txt

Note: for the URLs without a tilde, the server configuration determines whether the filename is absolute or relative. On servers which do not restrict users to their home areas, the tilde notation will not work.
