Redirecting Output from within Batch file

I am creating a batch file with some simple commands to gather information from a system. The batch file contains commands to get the time, IP information, users, etc.

I assembled all the commands in a batch file, and it runs, but I would like the batch file, when run to output the results to a text file (log). Is there a command that I can add to the batch that would do so?

Keep in mind I do not want to run the batch from cmd, then redirect output ; I want to redirect the output from inside the batch, if that is possible.

Add these two lines near the top of your batch file, all stdout and stderr after will be redirected to log.txt:

if not "%1"=="STDOUT_TO_FILE"  %0 STDOUT_TO_FILE %*  >log.txt 2>&1
shift /1

@echo OFF
[your command] >> [Your log file name].txt

I used the command above in my batch file and it works. In the log file, it shows the results of my command.

Adding the following lines at the bottom of your batch file will grab everything just as displayed inside the CMD window and export into a text file:

powershell -c "$wshell = New-Object -ComObject wscript.shell; $wshell.SendKeys('^a')
powershell -c "$wshell = New-Object -ComObject wscript.shell; $wshell.SendKeys('^c')
powershell Get-Clipboard > MyLog.txt

It basically performs a select all -> copy into clipboard -> paste into text file.

This may fail in the case of "toxic" characters in the input. Considering an input like thisIsAnIn^^^^put is a good way how to get understand what is going on. Sure there is a rule that an input string MUST be inside double quoted marks but I have a feeling that this rule is a valid rule only if the meaning of the input is a location on a NTFS partition (maybe it is a rule for URLs I am not sure). But it is not a rule for an arbitrary input string of course (it is "a good practice" but you cannot count with it).
