Command line interface Shorthand syntax is also available for remote connection arguments: -u username -pw password -pwf password file -p port -s server Example: On a remote XenServer Host: xe vm-list -u myuser -pw mypassword -s hostname Arguments are also taken from the environment variable XE_EXTRA_ARGS, in the form of comma-separated key/value pairs. For example, in order to enter commands on one XenServer Host that are run on a remote XenServer Host, you could do the following: export XE_EXTRA_ARGS="server=jeffbeck,port=443,username=root,password=pass" and thereafter you would not need to specify the remote XenServer Host parameters in each xe command you execute. Using the XE_EXTRA_ARGS environment variable also enables tab completion of xe commands when issued against a remote XenServer Host, which is disabled by default. 5.2. Special characters and syntax To specify argument/value pairs on the xe command line, write argument=value without quotes, as long as value doesn't have any spaces in it. There should be no whitespace in between the argument name, the equals sign (=), and the value. Any argument not conforming to this format will be ignored. For values containing spaces, write: argument="value with spaces" If you use the CLI while logged into a XenServer Host, commands have a tab completion feature similar to that in the standard Linux bash shell. If you type, for example xe vm-l and then press the TAB key, the rest of the command will be displayed when it is unambiguous. If more than one command begins with vm-l, hitting TAB a second time will list the possibilities. This is particularly useful when specifying object UUIDs in commands. Note When executing commands on a remote XenServer Host, tab completion does not normally work. However if you put the server, username, and password in an environment variable called XE_EXTRA_ARGS on the machine from which you are entering the commands, tab completion is enabled. See Section 5.1, "Basic xe syntax" for details. 48
