rvmutl, the RVM Maintenance Utility
rvmutl is the maintenance utility for RVM. Its principle features are log creation and maintenance, but there are also status and statistic display commands as well as printing commands for log records. A search facility for modifications to segments gains additional functionality from the log by allowing its use as a debugging history.
rvmutl is included in the bin directory of the RVM
distribution directory. It can be invoked with a single, optional
parameter, which is interpreted as the name of a log file to be opened.
If the file doesnt exist, rvmutl will ask if you wish to create
and initialize a log with the specified name.
rvmutl prompts for commands with a * prompt, after which commands can be typed. Most commands have one or more parameters, which are separated by one or more spaces. In general, command names can be abbreviated, provided that sufficient characters are typed to uniquely specify a command. To allow typing short-cuts, some non-unique abbreviations have defined interpretations. These are specified with the command documentation
As an example, the following sequence will initialize the file log_file to have one megabyte of log record space:
% rvmutl
* init_log log_file 1M
* quit
After this simple sequence, the log file is ready for use.
The following manual page describes the commands available in rvmutl.
