Batch scripting: output is empty when trying to echo file content

Question

i'm trying to loop through all installed programs:

wmic /output:C:\temp\InstallList.txt product get name

for /F "tokens=*" %%G in (C:\temp\InstallList.txt) do echo %%G

the file is created, but the output is empty!

Answer 1

The output is not empty. The output is in Unicode. Use more to convert into current local encoding.

If you would like the whitespace removed from the end of the strings, see How to remove trailing and leading whitespace for user-provided input in a batch file?

setlocal enabledelayedexpansion
wmic product get name | more >"C:\temp\InstallList.txt"
for /F "skip=1 usebackq tokens=*" %%G in (`type "C:\temp\InstallList.txt"`) do (
    set S=%%G
    set S=!S:~0,-1!
    if "!S!" NEQ "" (echo !S!)
)
