URLs
The arguments for the 7210 SAS 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).
7210 SAS 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 12.
Table 12: URL types and Syntax
The system accepts either forward slash (“/”) or backslash (“\”) characters to delimit directory 
and/or filenames in URLs. Similarly, the 7210 SAS 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 
system before transmission. On systems where the client treats the backslash like an “escape” 
character, a double backslash “\\” or the forward slash “/” can typically be used to properly delimit 
directories and the filename.
URL Type Syntax Notes
local-url [cflash-id:\]path
[usb-flash-id:\]path
cflash-id is the compact flash device name.
Values: cf1: and cf2:\ (only on 7210 SAS-T)
usb-flash-id is the USB device name.
Values: uf1:
ftp-url ftp://[username[:password]@]host/path 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
ftp://[username[:password]@]host/./path A relative ftp path from the user’s home 
directory. Note the period and slash (“./”) in this 
syntax compared to the absolute path.
tftp-url tftp://host[/path]/filename tftp is only supported for operations on file-urls.
