 **Note:** **Note:**
 When JSexec starts up, it changes its **current working directory** to the Synchronet ''[[dir:ctrl]]'' directory. If you pass filenames on the command-line to a module, the paths must be full/absolute paths or relative to the Synchronet ''[[dir:ctrl]]'' directory. When JSexec starts up, it changes its **current working directory** to the Synchronet ''[[dir:ctrl]]'' directory.

 +==== Log Level ==== 
 +
 +The log severity/output verbosity level can be controlled via the ''[[dir:ctrl]]/[[config:jsexec.ini]]'' file or specified using the ''-L'' command-line option. The value following ''-L'' can either be the numeric log level (''7'' being the lowest-severity / most verbose output) or a [[http://wiki.synchro.net/config:ini_files#enumerated_values|word]] describing the log level (e.g. ''-Ldebug'' for debug-level logput).

 This allows JSexec scripts to be executed easily via [[:howto:apache|CGI]] as well as other command-line conveniences on Unix-like operating systems. This allows JSexec scripts to be executed easily via [[:howto:apache|CGI]] as well as other command-line conveniences on Unix-like operating systems.
  
 +===== Output =====
 +
 +JSexec supports multiple output methods and streams:
 +
 +  - **Error** (default stream: ''stderr'')\\ JS ''log()'' messages with log-levels of ''LOG_ERR'' or lower
 +  - **Status** (default stream: ''stderr'')\\ JS ''log()'' messages with log-levels higher than ''LOG_ERR''\\ JSexec startup/compile/shutdown progress messages
 +  - **Console** (default stream: ''stdout'')\\ JS ''write()'' ''writeln()'' ''printf()'' ''alert()'' and ''prompt()'' messages
 +
 +==== syslog ====
 +
 +When JSexec is executed on *nix operating systems with the ''-d'' (Daemonize) option, all JS ''log()'' messages are directed to ''syslog''.
 +
 +==== Suppression ====
 +  * **Status** output is suppressed by default when JSexec is run without a controlling TTY. This behavior can be overridden with the ''-A'' and ''-S'' command-line options.
 +  * **Status** output can be manually suppressed with the ''-n'' (Null) command-line option.
 +  * **Console** output can be suppressed with the ''-q'' (Quiet) command-line option. 
 +
 +==== Redirection ====
 +  * The output streams may be redirected to specific filenames via command-line options.
 +  * **Error** output can be forked to both ''stderr'' and a specified filename via the ''-e'' command-line option.
