Generally: commands in one-liner style do not enhance the readability all too much. If you don't understand it it is a good idea to first write it out, like i have done:


Code:
sed -n '/{/ ! b          # Line rule ("!"=NOTted): if line (not) contains "{", branch
        :a               # target for branching
        /}/ ! {          # line rule (NOTted again): if line (not) contains "}" do
              $ ! {      # line rule (NOTted again): if line is (not) the last line, do
                    N    # append next line to pattern space
                    ba   # branch to target a (see above, line 2)
                  }
              }
        {                # i don't understand this bracket
            /}/p         # line rule: if line contains "}" print it
        }' test.trc

I hope this helps.

Gendarme(Gendarme 2.6.2.0)												Gendarme(Gendarme 2.6.2.0)

NAME

       Gendarme - Rule-based code analysis for Mono.

FILE FORMATS

       ignore-file
	      This file is used to filter out defects from gendarme reports. It uses a line oriented file format where the first characters of the
	      line control the interpretation of the line:
	      # - means that the line is a comment.
	      R: - if the full name of a rule to be filtered.
	      A: - is used to filter out an assembly (the extension can be omitted).
	      T: - is used to filter out a namespace qualified type name.
	      M: - is used to filter out a method. It must contain the full method name as it appears in the report.

       rules.xml
	      This file is used in conjunction with the --set option to control and configure the rules used by Gendarme. It  contains	a  set	of
	      named  rules  (rule  sets)  and  each  rule  set contains a list of rules. Rules have required from and include attributes, optional
	      exclude and applyTo attributes, and optional parameter child elements.

	      The from attribute is the path of a dll to load ("Gendarme.Rules.BadPractice.dll").  Relative paths are  relative  to  the  gendarme
	      executable.

	      The include attribute may be "*" to match every rule in the dll or a list of rule names separated by '|' ("WhizBangRule | MyRule").

	      The  exclude  attribute is a list of rule names separated by '|' ("IckyRule").  These will override any rules matched by the include
	      attribute.

	      The applyTo attribute may be "all", "visible", or "nonvisible". If it is all (the default) then all  types  in  the  assemblies  are
	      checked,	if  it is visible then only the externally visible types are checked, if it is nonvisible then only the internally visible
	      types are checked.

	      The parameter child element is used to customize the behavior of a rule within a dll.  It has three required attributes: rule, prop-
	      erty,  and  value. rule is the name of the applicable rule ("AvoidSmallNamespaceRule"), property is the name of a public property in
	      the rule ("Minimum"), value is the value to assign to the property ("10").

       gendarme.exe.config
	      Used by debug versions of Gendarme to enable logging for rules. A config file will be generated automatically by the make  file.	To
	      enable logging for a rule edit the config file, add a switch using the rule's name, and set the value to 1.
