Wrong command using sed, in more folders, listed with grep

Question

Here my script to do refactorging with PHP. I've created a command that works inside vim, but only inside a folder.

!for i in `grep -Rl OldName foldername/`; do sed -i 's/OldName/NewName/g' $i; done;

What I am asking here, is the update to this script, that allow me to run sed in more folders, with one single command. I've tried this:

!for i in `grep -Rl OldName .{a,b,c}/`; do sed -i 's/OldName/NewName/g' $i; done;

But does not works. Can some one suggest me the fix?

Answer 1

You can just use find and sed like this:

find {src,test,scripts} -type f -exec sed -i 's/OldName/NewName/g' {} +

find command will find all the files in folders src,test,scripts in current directory and sed will perform inline substitution.

Answer 2

for i in $(grep -Rl OldName src/ test/ scripts/); do sed -i 's/OldName/NewName/g' "$i" ; done;

You can give a list of directories to search as shown above. like src/ test/ scripts/ .
