Shell - DTracing Shell Scripting
|
||
|
|
|
||
|
|
These scripts trace activity of various shell programming languages,
|
||
|
|
and make use of specific shell DTrace providers, which are either
|
||
|
|
integrated or available for download from the shells page listed below.
|
||
|
|
Each script has a prefix to make the shell language clear.

sh - the Bourne Shell. This provider was written by Alan Hargreaves and
|
||
|
|
is currently available both as a diff and in binary form from the shells
|
||
|
|
page.
|
||
|
|
|
||
|
|
Since the DTrace Shell providers are under development, there is a chance
|
||
|
|
that they have changed slightly by the time you are reading this, causing
|
||
|
|
these scripts to either break or behave oddly. Firstly, check for newer
|
||
|
|
versions of the DTraceToolkit; if it hasn't been updated and you need
|
||
|
|
to use these scripts immediately, then updating them shouldn't take
|
||
|
|
too long. The following was the state of the providers when these scripts
|
||
|
|
were written - check for changes and update the scripts accordingly,
|
||
|
|
|
||
|
|
provider sh {
|
||
|
|
probe function-entry(file, function, lineno);
|
||
|
|
probe function-return(file, function, rval);
|
||
|
|
probe builtin-entry(file, function, lineno);
|
||
|
|
probe builtin-return(file, function, rval);
|
||
|
|
probe command-entry(file, function, lineno);
|
||
|
|
probe command-return(file, function, rval);
|
||
|
|
probe script-start(file);
|
||
|
|
probe script-done(file, rval);
|
||
|
|
probe subshell-entry(file, childpid);
|
||
|
|
probe subshell-return(file, rval);
|
||
|
|
probe line(file, lineno);
|
||
|
|
};
