Based on answers and comments from this question, I cannot understand how to add a double-pipe ||
statement with two commands using the &&
on a for
loop. Consider the following example taken from here:
@echo off
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"
set "datestamp=%YYYY%%MM%%DD%" & set "timestamp=%HH%%Min%%Sec%"
set "fullstamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%"
echo datestamp: "%datestamp%"
echo timestamp: "%timestamp%"
echo fullstamp: "%fullstamp%"
pause
If I try
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a" || echo Error while getting datetime. >> %someoutputfile% && GOTO endthis
I get a Unexpected &&
error. I tried adding parenthesis around the each command after the ||
but they too give Unexpected )
similar errors.
Can someone explain what I am doing wrong? Should I put the ||
commands before the do set "dt=%%a"
or something?
