Finding specific folder within path, and add altered version to the %PATH% [duplicate]

Question

I'm looking to find path with client_1 string, replace client_1 part with client_1\bin, and set PATH=%PATH%;%newpath%.

I've tried

@echo off
setlocal EnableDelayedExpansion

set newpath=
for %%a in ("%path:;=";"%") do (
    rem @echo %%~a
    if [%newpath%]==[] (
        echo %%~a | findstr /I /C:"client_1" >nul
        if not errorlevel 1 (
            set newpath=%%~a
            set newpath=!newpath:client_1\bin=client_1!
        )
    )
)

set PATH=%PATH%;%newpath%

Does this answer your question? Variables are not behaving as expected Specifically, since you're setting and using a variable inside of the same set of parentheses, you need to add setlocal enabledelayedexpansion to the top of your script and use !newpath:client_1\bin=client_1! instead of %newpath:client_1\bin=client_1%. — SomethingDark

Could you elaborate on how it's failing? Is the variable not getting created at all? — SomethingDark

Could you please explain what you're seeing and what you're expecting to see? I'd expect someone with 50k rep to know better than to respond with "it isn't working" when asked for elaboration. — SomethingDark

Substitution part was also wrong beside missing EnableDelayedExpansion, and condition around newpath var also needed to use ! instead of %.

@echo off
setlocal EnableDelayedExpansion

set newpath=
for %%a in ("%path:;=";"%") do (
    rem @echo %%~a
    if [!newpath!]==[] (
        echo %%~a | findstr /I /C:"client_1" >nul
        if not errorlevel 1 (
            set newpath=%%~a
            set newpath=!newpath:client_1=client_1\bin!
        )
    )
)

set PATH=%PATH%;%newpath%
