URLs
The arguments for the SR OS file commands are modeled after standard universal resource locator
(URL). A URL refers to a file (a file-url) or a directory (a directory-url).
The 7950 SR OS supports operations on both the local file system and on remote files. For the
purposes of categorizing the applicability of commands to local and remote file operations, URLs
are divided into three types of URLs: local, ftp and tftp. The syntax for each of the URL types are
listed in
Table 16: URL Types and Syntax
URL Type
local-url
[cflash-id:\]path
ftp-url
ftp://[username[:password]@]host/path
ftp://[username[:password]@]host/./path
tftp-url
tftp://host[/path]/filename
Note that if the host portion of the URL is an IPv6 address, then the address should be enclosed in
square brackets. For example:
The system accepts either forward slash ("/") or backslash ("\") characters to delimit directory
and/or filenames in URLs. Similarly, the The SR OS SCP client application can use either slash or
backslash characters, but not all SCP clients treat backslash characters as equivalent to slash
characters. In particular, UNIX systems will often times interpret the backslash character as an
"escape" character. This can cause problems when using an external SCP client application to
send files to the SCP server. If the external system treats the backslash like an escape character, the
backslash delimiter will get stripped by the parser and will not be transmitted to the SCP server.
For example, a destination directory specified as "cf1:\dir1\file1" will be transmitted to the SCP
server as "cf1:dir1file1" where the backslash escape characters are stripped by the SCP client

Values: cf1:
An absolute ftp path from the root of the remote
file system.
username is the ftp user name
password is the ftp user password
host is the remote host
path is the path to the directory or file
A relative ftp path from the user's home
