In command prompt - How do I export all the content of the screen to a text file(basically a copy command, just not by using right-clicking and the clipboard)
This command works, but only for the commands you executed, not the actual output as well
doskey /HISTORY > history.txt
If you want to append a file instead of constantly making a new one/deleting the old one's content, use double > marks. A single > mark will overwrite all the file's content.
Overwrite file
MyCommand.exe>file.txt
^This will open file.txt if it already exists and overwrite the data, or create a new file and fill it with your output
Append file from its end-point
MyCommand.exe>>file.txt
^This will append file.txt from its current end of file if it already exists, or create a new file and fill it with your output.
Update #1 (advanced):
My batch-fu has improved over time, so here's some minor updates.
If you want to differentiate between error output and normal output for a program that correctly uses Standard streams, STDOUT/STDERR, you can do this with minor changes to the syntax. I'll just use > for overwriting for these examples, but they work perfectly fine with >> for append, in regards to file-piping output re-direction.
The 1 before the >> or > is the flag for STDOUT. If you need to actually output the number one or two before the re-direction symbols, this can lead to strange, unintuitive errors if you don't know about this mechanism. That's especially relevant when outputting a single result number into a file. 2 before the re-direction symbols is for STDERR.
Now that you know that you have more than one stream available, this is a good time to show the benefits of outputting to nul. Now, outputting to nul works the same way conceptually as outputting to a file. You don't see the content in your console. Instead of it going to file or your console output, it goes into the void.
STDERR to file and suppress STDOUT
MyCommand.exe 1>nul 2>errors.txt
STDERR to file to only log errors. Will keep STDOUT in console
MyCommand.exe 2>errors.txt
STDOUT to file and suppress STDERR
MyCommand.exe 1>file.txt 2>nul
STDOUT only to file. Will keep STDERR in console
MyCommand.exe 1>file.txt
STDOUT to one file and STDERR to another file
MyCommand.exe 1>stdout.txt 2>errors.txt
The only caveat I have here is that it can create a 0-byte file for an unused stream if one of the streams never gets used. Basically, if no errors occurred, you might end up with a 0-byte errors.txt file.
Update #2
I started noticing weird behavior when writing console apps that wrote directly to STDERR, and realized that if I wanted my error output to go to the same file when using basic piping, I either had to combine streams 1 and 2 or just use STDOUT. The problem with that problem is I didn't know about the correct way to combine streams, which is this:
%command% > outputfile 2>&1
Therefore, if you want all STDOUT and STDERR piped into the same stream, make sure to use that like so:
MyCommand.exe > file.txt 2>&1
The redirector actually defaults to 1> or 1>>, even if you don't explicitly use 1 in front of it if you don't use a number in front of it, and the 2>&1 combines the streams.
Update #3 (simple)
Null for Everything
If you want to completely suppress STDOUT and STDERR you can do it this way. As a warning not all text pipes use STDOUT and STDERR but it will work for a vast majority of use cases.
STD* to null
MyCommand.exe>nul 2>&1
Copying a CMD or Powershell session's command output
If all you want is the command output from a CMD or Powershell session that you just finished up, or any other shell for that matter you can usually just select that console from that session, CTRL + A to select all content, then CTRL + C to copy the content. Then you can do whatever you like with the copied content while it's in your clipboard.
Just see this page
in cmd type:
Command | clip
Then open a *.Txt file and Paste. That's it. Done.
If you are looking for each command separately
To export all the output of the command prompt in text files. Simply follow the following syntax.
C:> [syntax] >file.txt
The above command will create result of syntax in file.txt. Where new file.txt will be created on the current folder that you are in.
For example,
C:Result> dir >file.txt
To copy the whole session, Try this:
Copy & Paste a command session as follows:
1.) At the end of your session, click the upper left corner to display the menu.
Then select.. Edit -> Select all
2.) Again, click the upper left corner to display the menu.
Then select.. Edit -> Copy
3.) Open your favorite text editor and use Ctrl+V or your normal
Paste operation to paste in the text.
If your batch file is not interactive and you don't need to see it run then this should work.
#echo off
call file.bat >textfile.txt 2>&1
Otherwise use a tee filter. There are many, some not NT compatible. SFK the Swiss Army Knife has a tee feature and is still being developed. Maybe that will work for you.
How about this:
<command> > <filename.txt> & <filename.txt>
Example:
ipconfig /all > network.txt & network.txt
This will give the results in Notepad instead of the command prompt.
From command prompt Run as Administrator. Example below is to print a list of Services running on your PC run the command below:
net start > c:\netstart.txt
You should see a copy of the text file you just exported with a listing all the PC services running at the root of your C:\ drive.
If you want to output ALL verbosity, not just stdout. But also any printf statements made by the program, any warnings, infos, etc, you have to add 2>&1 at the end of the command line.
In your case, the command will be
Program.exe > file.txt 2>&1

The vim manual page contains two similar -r type commands. I'll give more background below, this question is really how to invoke the first type of -r to list the swap files, but avoid the second -r that invokes recovery
-r List swap files, with information about using them for re‐
covery.
-r {file} Recovery mode. The swap file is used to recover a crashed
editing session. The swap file is a file with the same
filename as the text file with ".swp" appended. See ":help
recovery".
The -r without filename (the first -r above ) reports on the swap files of other files too, including ones in other directories
Background:
I'm trying to have vim report the swap files of a specific file (mostly to determine if vim still editing the file). If the file is being edited ( in another window, either on linux or cygwin ) I can 'raise' that window up to the top with "\e[2t\e[1t" as I have successfully be able to do thanks to Bring Window to Front
Vim has multiple swap file names, and multiple directories that it could put a file, so I want to ask vim, please tell me the name of the swap files that are currently in use for a given file, and if there is a current vim process on the file. Unfortunately, sometimes vim will open a command file in recovery mode in unexpected ways.
I'm invoking vim like this vim -r -c :q file, well actually, I'm invoking it from script, since I want vim to see something more like a terminal, then I look at the output file, so it's more like script -q -c "vim -r -c :q foo" fooscript, then I look in the fooscript file for messages like /Note: process STILL RUNNING: (\d+)/
It is beginning to look like I need to use vim -r without a file name, and parse the output of the -r report, and that there isn't a way to get the report pre-filtered to a single file in question.
after switching my focus to just vim -r, and
Knowing that vim will try to put the swap file into the same directory as the file it's editing ( thanks to #romainl for the pointer to :help swap-file )
observing that vim -r reports on the files in the current directory first,
observing that the file name associated with the swap file is reported before the process id of the vim process, and
observing that vim appends (STILL RUNNING) if it finds the active process
I changed the current directory appropriately and ran this code after plugging in the name of the file-to-search-for
perl -lne '
last if /^\s+In directory/;
undef $f if /^\d+/;
$f = $1 if /^\s+file name:\s+(.*)\s*$/;
if ( $f =~ m#/file-to-search-for# && /^\s+ process ID:\s(\d+).*?STILL RUNNING/ ) {
print $1;
$pid //= $1;
}
END { exit !$pid; } '
The pid of the running vim process is printed, and the exit status is zero when the appropiate swap file is found, and non-zero if the file was not being edited
I have a script which when it runs, prints out lines to the terminal (with errors). I would like to redirect this output into files.
I read that I should add this line in my PS1 script: ".\myscript.ps1 *> &1 > outfile.log" but it doesn't work because of ampersand character is not allowed.
You don't need space symbol before ampersand.
.\myscript.ps1 *>&1 will redirect all output streams to the stream number 1
.\myscript.ps1 *>outfile.log will redirect all output streams to the file
https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_redirection?view=powershell-6
If you just want to put your lines into another file from a terminal I would try this:
./myscript.ps1 2>outfile.log
"./" activates the script "2>" takes the stderr stream into (in this case) the outfile.log But I am not sure what you are supposed to do. Maybe if you could post your code or your task here that would be great.
if you want both streams in one outlog, I would do it like that "2>&1"
I'm writing a batch script that, among other things, opens a macro enabled excel file (.xlsm):
2>nul (
>>%CSF% echo off
) && (start "cmdTitle" /B excel %CSF% /e /automation) || (echo could not open)
%CSF% is the variable referring to a full path to the excel file i.e. "C:\test\testfile.xlsm" (including the quotes for cases where there may be spaces in the directory / filename)
This code checks if the file is locked for editing, then if not it opens the file (start command) otherwise echos could not open.
If I open the file from windows explorer or run just the following in a batch script the file opens fine.
set CSF="C:\Test Folder\Test.xlsm"
start "cmdTitle" /B excel %CSF% /e /automation
However, running the batch file when checking for a locked file always causes excel to say, "Excel found unreadable content in 'filename.xlsm' Do you want to recover the contents of this workbook?" which removes the macros from the file.
EDIT: In addition to the file not opening correctly, any excel add-ins that do something upon excel opening, for example, removing and recreating a command bar also fail to load: "Addin.xla cannot be accessed"
What is causing the difference in behavior between running the command alone and in redirection?
TIA
Examine the end of the file in a hex viewer and see what, if anything, is appended to the end.
Your code as posted works fine (echoing the excel command too). Some other code is likely to be the problem.
I have a windows batch file, which iterates over files in a folder and runs a command on each file. Specifically I am running xmllint to validate some files:
for %%i in (c:\temp\*.xml) do (
C:\XMLLINT\xmllint -noout -schema "C:\schemas\schema.xsd" "%%~dpnxi" >> c:\output.txt
)
It currently shows the output on screen. I want to show the output of all these commands placed in an output file. How can I achieve this? By using the append operator (>>) nothing is accomplished except for a blank file being created.
Is it because of xmllint?
If you're trying to redirect error output from the program, it might be writing to stderr. You can try to redirect it with:
for %%i in (c:\temp\*.xml) do (
C:\XMLLINT\xmllint -noout -schema "C:\schemas\schema.xsd" "%%~dpnxi" >> c:\output.txt 2>&1
)
Basically the 2>&1 at the end means redirect anything from stderr (which is 2) to stdout (which is 1). Since stdout is redirected to a file, you should now see the stderr stream in the file. Hope this works for you!
I've never used it, but if its documentation is here, have you tried just removing your "-noout" option, or adding an: "-output c:\output.txt"?
I have two files in the same folder that I'd like to run. One is a .txt file, and the other is the program shortcut to an .exe. I'd like to make a batch file in the same location to open the text file and the shortcut then close the batch file (but the text file and program remain open).
I tried this with no luck:
open "myfile.txt"
open "myshortcut.lnk"
Also didn't work:
start "myfile.txt"
start "myshortcut.lnk"
I was able to figure out the solution:
start notepad "myfile.txt"
"myshortcut.lnk"
exit
This would have worked too. The first quoted pair are interpreted as a window title name in the start command.
start "" "myfile.txt"
start "" "myshortcut.lnk"
Don't put quotes around the name of the file that you are trying to open; start "myfile.txt" opens a new command prompt with the title myfile.txt, while start myfile.txt opens myfile.txt in Notepad. There's no easy solution in the case where you want to start a console application with a space in its file name, but for other applications, start "" "my file.txt" works.
The command-line syntax for opening a text file is:
type filename.txt
File types supported by this command include (but are not limited to): .doc, .txt, .html, .log
If the contents is too long, you can add "|more" after "type filename.txt", and it will pause after each screen; to end the command before the end of the file, you can hold Ctrl + C.
I use
#echo off
Start notepad "filename.txt"
exit
to open the file.
Another example is
#echo off
start chrome "filename.html"
pause
You can also do:
start notepad "C:\Users\kemp\INSTALL\Text1.txt"
The C:\Users\kemp\Install\ is your PATH. The Text1.txt is the FILE.
"location of notepad file" > notepad Filename
C:\Users\Desktop\Anaconda> notepad myfile
works for me! :)
In some cases, when opening a LNK file it is expecting the end of the application run.
In such cases it is better to use the following syntax (so you do not have to wait the end of the application):
START /B /I "MyTitleApp" "myshortcut.lnk"
To open a TXT file can be in the way already indicated (because notepad.exxe not interrupt the execution of the start command)
START notepad "myfile.txt"
The command start [filename] opened the file in my default text editor.
This command also worked for opening a non-.txt file.
If you are trying to open an application such as Chrome or Microsoft Word use this:
#echo off
start "__App_Name__" "__App_Path__.exe"
And repeat this for all of the applications you want to open.
P.S.: This will open the applications you select at once so don't insert too many.
Try using:
#ECHO off
ECHO Hello World!
START /MAX D:\SA\pro\hello.txt
Its very simple,
1)Just go on directory where the file us stored
2)then enter command i.e. type filename.file_extention
e.g type MyFile.tx
To open a file with default software just need to type the path of the file or, if you are at the file location, the file name.
C:\Users\MyName>C:\User\MyName\Desktop\hello.txt
or
C:\Users\MyName\Desktop>hello.txt
If you want specific program like notepad you can specify it first.
C:\Users\MyName>notepad C:\User\MyName\Desktop\hello.txt
or
C:\Users\MyName\Desktop>notepad hello.txt
Note that notepad is usually default text editor for .txt, in this case would make more sense to type notebook only to open a .cs/.cpp/.py file if your default for that files is any IDE and you just want to see the file on notebook
Regarding the batch file it will work the same way but to open them at the same time and let the command line go away you should use:
start "title" {filename}
So the command can open the file and return to next line immediately.
start "" C:\Users\MyName\MyFolder\foo.exe
start "" C:\Users\MyName\MyFolder\notes.txt
or
start "" foo.exe
start "" notes.txt
The last one only works if the batch file is on the same location of the files.
If you plan on using the console to open the batch file and you want the console to close at the end you should indeed write exit on last line.
When in doubt, it always helps to read the docs:
>help start
