ECHO命令回显仅显示文件的最后一行，而不显示每行

Question

I want to show out of the console each line from a file. I try this:

findstr /v /b /c:" " <%1>toto
for /f "tokens=*" %%a in (toto) do set co=%%a 
echo. %co%

Also this one:

findstr /v /b /c:" " <%1>toto
for /f "tokens=*" %%a in (toto) do (set co=%%a 
echo. %co%
)

But the first way shows me only the last line of file and the second one doesn't show me anything.

Someone can explain me what's wrong in these latter and how to get in the 'co' variable each line printed on the console?

Thanks

Answer 1

you override co. to append to it try set co=%co% %%a

Answer 2

尝试这个：

for /f "tokens=1*delims=:" %%a in ('findstr /n "^" "toto"') do echo %%b
