Is there anyway to write the command windows output to a file? To have a transcript if you will.
Yes, for example, on the command prompt you can do this:
dir *.* > c:\temp\a.txt
This operation is called 'output redirection'. The output of the above command will go the named file and will overwrite it if it already exists with the results. You can find many examples on the net for that, example: Redirection.
In command prompt, use >> operator.
For example, If you type below command then output will be saved to output.txt file
dir > output.txt
If you type below then output will be appended to exist file.
dir >> output.txt

Is there anyway i can print the command being executed and result of the command in batch to a file but not the console.
Examples:
ls C:\Temp
I want to print ls C:\Temp and result of this command to log file but not on console
call :function "Argument 1"
I want to print call :function "Argument 1" and result of this command to log file but not on console
call perl hey.pl
I want to print call perl hey.pl and result of this command to log file but not on console
command > output.txt
Will create an output file "output.txt" (You can also use ".log"). If such a file exists, it will overwrite it.
command >> output.txt
Will also create an output file, but it will append to it (Useful when you're in a loop and want to append the results of all of the iterations).
Create your batch file, e.g. C:\YourDir\YourBatch.cmd, making sure that you have not turned Echo Off.
At your Command prompt run the batch file.
Either by navigating to the holding path:
CD /D "C:\YourDir"
then invoking
"YourBatch.cmd">"Output.log"
or just run it directly with:
"C:\YourDir\YourBatch.cmd">"C:\YourDir\Output.log"
If you intend to append to an existing Output.log change > to >>.
I wanted to make a logging function for my batch app and what I want this function to do is save the output of a command. As an example lets take a simple command such as
copy "data" "C:\Program Files"
where in the folder data is "text.txt" & "text2.txt". The output of the command would be
C:\users\%username%\desktop\testFolder\data\text.txt -> C:\Program Files\data\
C:\users\%username%\desktop\testFolder\data\text2.txt -> C:\Program Files\data\
2 file(s) copied
I want this to be saved into lets say "output.log" which would be in the same folder as the folder "data" which was copied. is there a way to do this?
> character is what you need.
command > log.txt
Creates and overwrite content of log.txt with command result.
command >> log.txt
Creates or append content of log.txt with commandresult.
command >> log.txt 2>&1
Creates or append content of log.txt with command result and error.
I have a batch file with multiple commands:
XCOPY C:\File_path C:\Destination
RENAME C:\File_path New_name
DEL C:\File_path
I need them to write the outputs in the same text file. In this way at the end of the process I have txt file with all the procedure and I can check if everything has been done correctly.
I tried with the following command after each single command/step:
command 1> output.txt 2>&1
but it rewrites the file. It does not keep the output of all the steps but just the last one. How can I do it?
Thanks
According to MS you probably should be using the "append" operator - >>.
This is the article:
https://technet.microsoft.com/en-us/library/bb490982.aspx
use append operator. It will append your output to existing file. Instead of overwriting it.
command 1 >> output.txt 2>&1
Inside batch file, command by command
> output.txt 2>&1 xcopy ...
>> output.txt 2>&1 rename ...
>> output.txt 2>&1 del ...
> will overwrite/create the text file and >> will append to it
Or, wrapping commands inside a block
> output.txt 2>&1 (
xcopy ...
rename ...
del ...
)
Or, outside batch file
myBatchFile.cmd > output.txt 2>&1
If you want to append to a .txt file, you should use >> instead of >
I have given a bat file that I should run on development server which does some updates.
It has multiple commands and I would like to keep the results in txt file.
Should I add after each command >> result.txt or I can add it somewhere in the end of bat file and everything will be written in that?
You have four options:
Run the batch file at the command line like: myBat.bat >> outPut.txt
Script the above in another batch file and run that
Insert the >> after each command ( Note: the >> appends to file, while > overrides existing text output file)
Enclose all relevant lines in parentheses and script >> result.txt once at the end of the script
I'm trying to save the output of an exe file executed within a batch file to a text file.
I've tried the the following methods but they don't work
This doesn't work since I'm back at the command prompt while the application runs and the text file created is blank.
C:\>myexec.exe > mytext.txt
C:\>_
C:\>Status: Passed
These also doesn't work. I get an empty text file and no output.
C:\>start /wait myexec.exe > mytext.txt
C:\>call start /wait myexec.exe > mytext.txt
This gives me an output at least:
C:\>start /wait myexec.exe
Status Passed
Use /B operator.
This will cause the output to be redirected
start /B /wait myexec.exe > mytext.txt
I had the same issue and solved it like this:
bat file content
START /wait cmd /c "F:\MyInstaller\installer.exe > log.txt"
echo This will get logged after the previous is completed > log1.txt
The & redirection operator duplicates output or input from one specified handle to another specified handle. For example, to send dir output to File.txt and send the error output to File.txt, type:
dir>c:\file.txt 2>&1
Try Application.exe >& file.txt. This will output both, standard output and error stream, to your file.
