When supplying an argument (such as a dump_level or date in the previous example), you can omit the option (such as -level or -expires in the example) associated with the argument if
· All arguments supplied with the command are entered in the order in which they appear in the command's syntax. (The syntax for each command is presented with its description in Part 2 of this guide and reference.)
· Arguments are supplied for all options that precede the option to be omitted.
· All options that precede the option to be omitted accept only a single argument.
· No options, either those that accept an argument or those that do not, are supplied before the option to be omitted.
In the case where two options are presented in { | } (braces separated by a vertical bar), the option associated with the first argument can be omitted if that argument is provided; however, the option associated with the second argument is required if that argument is provided.
If you must provide an option, you can abbreviate it to the shortest possible form that distinguishes it from other options of the command. For example, the -server option found in many DFS commands can typically be omitted or abbreviated to be simply -s.
You can also abbreviate a command name to the shortest form that still distinguishes it from the other command names in its suite. For example, you can shorten the fts help command to fts h because no other command names in the fts command suite begin with the letter "h." However, there are several fts commands that begin with the letter "l," such as fts lsquota, fts lsmount, and others. To avoid ambiguity, you can abbreviate these commands to fts lsq and fts lsm; other fts command names that begin with "l" can be abbreviated in a similar fashion. Note that because miscellaneous DFS commands are not included in a suite, their names cannot be abbreviated.
The following example illustrates three acceptable ways to enter the same fts lsquota command:
· Complete command:
$ fts lsquota -path jlw/doc jlw/public
· Abbreviated command name and abbreviated option:
$ fts lsq -p jlw/doc jlw/public
· Abbreviated command name and omitted option:
$ fts lsq jlw/doc jlw/public
Note: The dfs_login and dfs_logout commands provided with the DFS/NFS Secure Gateway do not provide the shortcuts and help available with other DFS commands. See the reference pages for these two commands for information about using the commands.
