+ *W* This creates or overwrites the init file with the current settings.
+
+ This key is disabled if *--no-init-file* was specified on the
+ command line or if *overwrite-init-file false* is given in the init
+ file.
+
+INIT FILE
+ When virt-top starts up, it reads initial settings from the file
+ *.virt-toprc* in the user's home directory.
+
+ The name of this file may be overridden using the *--init-file filename*
+ command line option or may be disabled entirely using *--no-init-file*.
+
+ The init file has a simple format. Blank lines and comments beginning
+ with *#* are ignored. Everything else is a set of *key value* pairs,
+ described below.
+
+ display *task|pcpu|block|net*
+ Sets the major display mode to one of *task* (tasks, the default),
+ *pcpu* (physical CPUs), *block* (block devices), or *net* (network
+ interfaces).
+
+ delay *secs*
+ Sets the delay between display updates in seconds.
+
+ hist-cpu *secs*
+ Sets the historical CPU delay in seconds.
+
+ iterations *n*
+ Sets the number of iterations to run before we exit. Setting this to
+ *-1* means to run continuously.
+
+ sort *cpu|mem|time|id|name|...*
+ Sets the sort order. The option names are the same as for the
+ command line *-o* option.
+
+ connect *uri*
+ Sets the default connection URI.
+
+ debug *filename*
+ Sets the default filename to use for debug and error messages.
+
+ csv *filename*
+ Enables CSV output to the named file.
+
+ csv-cpu *true|false*
+ Enable or disable domain CPU stats in CSV output.
+
+ csv-block *true|false*
+ Enable or disable domain block device stats in CSV output.
+
+ csv-net *true|false*
+ Enable or disable domain network interface stats in CSV output.
+
+ batch *true|false*
+ Sets batch mode.
+
+ secure *true|false*
+ Sets secure mode.
+
+ script *true|false*
+ Sets script mode.
+
+ end-time *time*
+ Set the time at which the program exits. See above for the time
+ formats supported.
+
+ overwrite-init-file *false*
+ If set to *false* then the *W* key will not overwrite the init file.
+
+ Note that in the current implementation, options specified in the init
+ file override options specified on the command line. This is a bug and
+ this behaviour may change in the future.
