Skipping last empty line of WMIC command output in batch

Question

I am trying to format the output of a command in JSON as such:

echo \"patches\" : {
set patches=\"wmic qfe get HotfixID\"
for /f \"skip=1\" %%i in (\' %patches%         


        

Answer 1

Skipping last empty line of WMIC command output in batch

The simplest solution is to use findstr to remove the blank lines:

for /f "skip=1" %%i in ('%patches% ^| findstr /r /v "^$"')

No extra for loop required.
