How do I run a Perl one liner from a makefile? -

I know that Pearl is very simple under a liner, works and makes a global replacement, for A; But how do I run it in MessFile?

  perl -pi -e "s / a / a / g" filename  

I have tried (now I think the rest post is junk Because the shell command increases the extension of a command line - I do not want!) The question is still standing!

  $ APP = $ (shell perl -pi -e "s / a / a / g" filename)  

without the following line and without < / P>

  EXE = $ (APP)  

and I always get the following error

  create: APP: command not found  

Which I think comes from the line APP starts

thanks

If you want to run Perl as part of a target action, you can use

 $ cat Makefile all: abc | Perl -pe 's / a / a / g' $ make echo ABC | (Note that the tab character is before  echo .)

 I  option files in-place To edit in, but it will confuse  create  (unless you are writing any) Targeting from a more common pattern sources is for example: 
 
 $ cat Makefile all: buzz: bar.in perl -pe 's / a / a / g' bar.in> bAr $ cat bar .in times $ make perl -pe 's / a / a / g' bar.in> bAr $ cat bar bAr
