You can choose an arbitrary executable. + IMPORTANT: The `script` plug-in is provided mainly for compatibility with earlier releases. Prefer other *TuneD* plug-ins if they cover the required functionality. + *TuneD* calls the executable with one of the following arguments: + -- ** `start` when loading the profile ** `stop` when unloading the profile -- + You need to correctly implement the `stop` action in your executable and revert all settings that you changed during the `start` action. Otherwise, the roll-back step after changing your *TuneD* profile will not work. + Bash scripts can import the [filename]`/usr/lib/tuned/functions` Bash library and use the functions defined there. Use these functions only for functionality that is not natively provided by *TuneD*. If a function name starts with an underscore, such as `_wifi_set_power_level`, consider the function private and do not use it in your scripts, because it might change in the future. + Specify the path to the executable using the `script` parameter in the plug-in configuration. + .Running a Bash script from a profile ==== To run a Bash script named `script.sh` that is located in the profile directory, use: ---- [script] script=${i:PROFILE_DIR}/script.sh ---- ==== cCsddiS)Nscript)selfrr#/usr/lib/python3.6/plugin_script.py_get_config_options6sz ScriptPlugin._get_config_optionscCs2d|_d|_|jddk r(|jd|_ng|_dS)NTFr)Z_has_static_tuningZ_has_dynamic_tuningZoptions_scripts)r instancerrr _instance_init<s zScriptPlugin._instance_initcCsdS)Nr)r r rrr _instance_cleanupFszScriptPlugin._instance_cleanupc Csd}x|D]}tj}|j|jjtjd|t|ftjdtt |j ytt |g|t t d|dtj j|d}|j\}}t|rtjd||dd f|jrtjd||jfd}Wq ttfk r } ztjd || fd}WYdd} ~ Xq Xq W|S) NTz'calling script '%s' with arguments '%s'zusing environment '%s')stdoutstderrZ close_fdsenvZuniversal_newlinescwdzscript '%s' error output: '%s'rz#script '%s' returned error code: %dFzscript '%s' error: %s)osenvironupdateZ _variablesZget_envloginfostrdebuglistitemsrrpathdirnameZ communicatelenerror returncodeOSErrorIOError) r scriptsZ argumentsretrrprocouterrerrr _call_scriptsIs,  zScriptPlugin._call_scriptscs$tt|j||j|jdgdS)Nstart)superr_instance_apply_staticr+r )r r ) __class__rr r.asz#ScriptPlugin._instance_apply_staticcstd}tt|j|||dkr d}dg}|r4|dg7}|j|j|dkrZtjtj|jntj tj |jd}|S)NTFZverifyignore_missing) r-r_instance_verify_staticr+r rrconstsZSTR_VERIFY_PROFILE_OKr!ZSTR_VERIFY_PROFILE_FAIL)r r r0Zdevicesr&args)r/rr r1es   z$ScriptPlugin._instance_verify_staticcsBdg}|tjkr|dg}|jt|j|tt|j||dS)NstopZ full_rollback)r2Z ROLLBACK_FULLr+reversedr r-r_instance_unapply_static)r r Zrollbackr3)r/rr r6ts   z%ScriptPlugin._instance_unapply_static)__name__ __module__ __qualname____doc__ classmethodr rrr+r.r1r2Z ROLLBACK_SOFTr6 __classcell__rr)r/r r s+    r)Z tuned.constsr2rZ tuned.logsZtunedr subprocessrrZlogsgetrZPluginrrrrr s
