| ## DynamoRIO @name@ script for Linux |
| ## |
| ## Usage for drrun or drinject: |
| ## For a single client, use the -c form and separate the application with --: |
| ## @name@ [-v] [-debug] [-dr_home <path>] [-logdir <path>] |
| ## [<dr_options>]* -c <path> [client_ops]* |
| ## -- <executable> [args ...] |
| ## |
| ## For multiple clients, use either of these forms: |
| ## @name@ [-v] [-debug] [-dr_home <path>] [-logdir <path>] |
| ## -client <path> <id> "<client_ops>" [<dr_options>]* |
| ## -- <executable> [args ...] |
| ## |
| ## @name@ [-v] [-debug] [-dr_home <path>] [-ops <dr_options>]* |
| ## [-logdir <path>] -client <path> <executable> [args ...] |
| ## |
| ## For drconfig, use the -reg or -unreg options described below. |
| ## |
| ## Option explanation: |
| ## [-v] Verbose output |
| ## [-debug] Use debug build of DynamoRIO (release is default) |
| ## [-@archother@] Use @archother@-bit DynamoRIO (default is @archdefault@-bit). This |
| ## should match what the client library and executable |
| ## being run were compiled for. |
| ## [-norun] Requests that an application NOT be run under DR |
| ## control. Useful for following all child processes |
| ## except a blacklist. DR will still be loaded, and |
| ## the app API available. |
| ## [-reg <executable>] Only for drconfig. Creates configuration file for |
| ## the specified application name. |
| ## [-unreg <executable>] Only for drconfig. Removes configuration file for |
| ## the specified application name. |
| ## [-dr_home <path>] Path to the DynamoRIO install. |
| ## Defaults to .. from @name@; may also be omitted |
| ## if DYNAMORIO_HOME is defined in the environment. |
| ## [-ops <dr_options>] DynamoRIO options (such as -stderr_mask 0xc |
| ## or -opt_memory: see docs). Can also be specified |
| ## with DYNAMORIO_OPTIONS in the environment. |
| ## Can be repeated. |
| ## If the application is separated by "--", the |
| ## "-ops" is not required. |
| ## [-logdir <path>] Path to logging directory. Defaults to ../logs from |
| ## @name@; may also be omitted if DYNAMORIO_LOGDIR |
| ## is defined in the environment. |
| ## [-c <path> <options>*] Registers one client to run alongside DR. Assigns |
| ## the client an id of 0. All remaining arguments |
| ## until the -- arg before the app are interpreted as |
| ## client options. Must come after all drrun and DR |
| ## ops. Incompatible with -client. Requires using -- |
| ## to separate the app executable. |
| ## [-client <path> <ID> "<options>"] |
| ## Register one or more clients to run alongside DR. |
| ## This option is only valid when registering a |
| ## process. The -client option takes three arguments: |
| ## the full path to a client library, a unique 8-digit |
| ## hex ID, and an optional list of client options |
| ## (use "" to specify no options). Multiple clients |
| ## can be installed via multiple -client options. In |
| ## this case, clients specified first on the command |
| ## line have higher priority. Neither the path nor |
| ## the options may contain semicolon characters. |
| ## <executable> [args...] The executable to run under DynamoRIO (and the args |
| ## to pass to it if running now). |
