If you talk about the classic stream editor

sed

and option

-r

that enables extended regex, then this can be done in MAC with


    sed -E

. Is this you talk about or i lost you? – George Vasiliou Apr 29 '17 at 14:17 yes, thats exactly what i meant. but i need to change it in the makefiles of the rom i am compiling. and i cant find wehre the sed -r is used. thank you for your answer. – flo071 Apr 30 '17 at 17:04 Welcome. You can just substitute all instances referring to


    sed -r

with


    sed -E

since it is the same thing. sed -E will work on mac and all other distros with no problem. – George Vasiliou Apr 30 '17 at 19:25 thank you!! but do you know which makefile in the build directory of an android source the sed -r is used? because i cant find it. – flo071 Apr 30 '17 at 23:06 Did you try something like


    grep -r 'sed -r' /android/dir/*

? This will scan all the files in a directory for sed -r. Or you can just


    grep 'sed -r' file

to search in a particular file – George Vasiliou Apr 30 '17 at 23:12 If you want to use

sed

instead of


    gsed

the


    --with-default-names

option does not work any more. Instead you have to add gnu-sed to the path:


    export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"

Editing PATH manually is one way. However, this is an alternative solution that might work for some.

Most of the developers these days have conda . conda can install the latest sed and make it visible via $PATH

conda install -c conda-forge sed

conda takes care of editing PATH variable

Most believe conda is a package manager for python, but that is not entirely true. I install everything using conda. And it manages environment variables such as


   PATH

really well. https://superuser.com/a/1304148/266871
