sed variable containing space error

[pablos_lordu]

Hello , i am trying to replace some code from all files in folder with something else but not manage to do it. i think that if source contains spaces there is my problem

#!/bin/sed -f
w="What to change"
grep -lR $w ./ | while read caca; do sed -i "s/$w/THE NEW VALUE/g" %caca done

hi,

what's that mess?

this kind of script can't have such a shebang!

%caca is not a valid variable, and you know it as you already used $w!

it's more probably the grep statement which errors, double quote $w:

grep -lR "$w" | while...

you're missing a semicolon before `done` too.
