Full Discussion: Find "*.c" and "Makefile" and then delete them with one line
Top Forums Shell Programming and Scripting Find "*.c" and "Makefile" and then delete them with one line Post 302908202 by balajesuri on Friday 4th of July 2014 12:01:46 PM

Code:
find . \( -name "*.c" -o -name "Makefile" \) -type f | xargs rm

This would be slightly quicker than running find with -exec switch because for each file the find command finds, the commands in exec would be executed; as against the xargs method where all the files are first found, and then the rm is applied over the entire list. For instance, if the find commands fetches 20 files, with the exec version, rm would be called 20 times. With the xargs version, it will be called only once. Of course, the difference may be very little.

Makefile::AST(3pm)					User Contributed Perl Documentation					Makefile::AST(3pm)

NAME

       Makefile::AST - AST for (GNU) makefiles

DESCRIPTION

       The structure of this (GNU) makefile AST is designed based on GNU make's data base listing output produced by "--print-data-base".

       This AST library provides the following classes:

       Makefile::AST
	   The primary class for ASTs. Provides interface for node adding and querying, such as "add_implicit_rule", "apply_implicit_rules",
	   "add_explicit_rule", "apply_explicit_rules", "add_var", "add_auto_var", "get_var", as well as lots of other utility functions, like
	   method "eval_var_value" for computing the ultimate values of makefile variables, method "enter_pad" and "leave_pad" for local
	   variable's scoping pad.

       Makefile::AST::Rule::Base
	   This is the base class for the rule nodes in the AST. It has properties like "normal_prereqs", "order_prereqs", "commands", and
	   "colon".

       Makefile::AST::Rule
	   This class represents the de-sugared form of simple rules and implicite rules after application. It inherits from
	   Makefile::AST::Rule::Base, and adds new properties "target" and "other_targets".

       Makefile::AST::Rule::Implicit
	   This class represents the implicit rule nodes in the AST. It inherits from Makefile::AST::Rule::Base, and adds new properties
	   "targets", "match_anything", and "is_terminal".

       Makefile::AST::StemMatch
	   This class encapsulates the file pattern matching (file names containing "%") and stem substitution algorithms.

       Makefile::AST::Variable
	   It represents the makefile variable nodes in the AST, including "name", "value", "flavor", and "origin".

       Makefile::AST::Command
	   Used to encapsulate information regarding makefile rule commands (e.g. command body, command modifiers "@", "-", "+", and etc.) as a
	   whole.

LIMITATIONS AND TODO

       Adding support for other flavors' makes into this AST library should make a huge amount of sense. The most interesting candiate is
       Microsoft's NMAKE.
