Replace sub-string in a FOR loop

Question

I want specific String later Path,

set PROJECT_FOLDER_PATH=E:\aaa\bbb\cccc
FOR /f %%i IN ('dir /b /s %PROJECT_FOLDER_PATH%\src\*.c') DO echo %%i:bbb\=%

Expected Result: cccc\src\test.c

but current Result: E:\aaa\bbb\cccc\src\test.c:bbb\=

Please, help me

You could check this post here and use the information of this one and combine them to get the result I think you needed. Also I recommend you to read the tour page to learn how this site works. — geisterfurz007

Is test.c a folder? Is it supposed to be in PROJECT_FOLDER_PATH? What is the purpose of the =? One way to do this would be to get the name of the parent folder before the FOR /f, like this: FOR %%a in (%PROJECT_FOLDER_PATH%) do SET parent=%%~na. Then you can use parent and a similar method to get the file name from the next FOR, and put them together. — soja

You cannot use the replace syntax on a parameter-style variable like %i. First store the value to a normal variable using set.

setlocal EnableDelayedExpansion

set PROJECT_FOLDER_PATH=E:\aaa\bbb\cccc
FOR /f %%i IN ('dir /b /s %PROJECT_FOLDER_PATH%\src\*.c') DO (
    set TMP_PATH=%%i
    echo !TMP_PATH:bbb\=!
)

We need Delayed expansion of variables to set and read the variable in the same loop. Otherwise, the variable in echo command would be expanded before entering the loop.
