They are handled differently from ordinary rules when the same target appears in more than one rule.
If they are identical, the text-if-true is effective; otherwise, the text-if-false, if any, is effective.
For example, the file function can be useful if your build system has a limited command line size and your recipe runs a command that can accept arguments from a file as ici paris make up afspraak well.We call this echoing because it gives the appearance that you are typing the lines yourself.This value is never touched by make again: in particular note that if you include files from other directories the value of curdir does not change.A copy of the license is included in the section entitled GNU Free Documentation License.It may not begin with a period.Is useful even in explicit rules when you wish to operate on only the prerequisites that have changed.RM geslacht bekend maken Command to remove a file; default rm -f.If a makefile has a rule which says how to update it (found either in that very makefile or in another one) or if an implicit rule applies to it (see Using Implicit Rules it will be updated if necessary.

Thus, either can contain side-effects (such as shell function calls, etc.) (or The or function provides a short-circuiting OR operation.
But if b is an intermediate file, then make can leave well enough alone.
