Write command line variable into text file
I've got as far as I can with this one, but struggling at the last hurdle.
I am attempting to get the uptime of my Windows 7 machine, load it into a variable, trim the current time from the left part of the variable and then write it back from a variable into a .txt file.
All works just fine, except I do not know how to write the variable back into a text file.
Here is what I have:
c: cd/ uptime.exe > uptime.txt set /p str=<uptime.txt echo.%str% set str=%str:~-16% echo.%str%
Now the last echo line displays exactly what I want, but how do I write that variable back into uptime.txt?
Thanks in advance for any assistance.
You can simply redirect standard output to the file of your choice to achieve your goal. For example:
echo %<name of environment variable>% > <path of file> echo %str% > uptime.txt
