How do I save terminal output to a file?


To write the output of a command to a file, there are basically 10 commonly used ways.

command > output.txt

The standard output stream will be redirected to the file only, it will not be visible in the terminal. If the file already exists, it gets overwritten.

command >> output.txt

The standard output stream will be redirected to the file only, it will not be visible in the terminal. If the file already exists, the new data will get appended to the end of the file.

command 2> output.txt

The standard error stream will be redirected to the file only, it will not be visible in the terminal. If the file already exists, it gets overwritten.

command 2>> output.txt

The standard error stream will be redirected to the file only, it will not be visible in the terminal. If the file already exists, the new data will get appended to the end of the file.

command &> output.txt

Both the standard output and standard error...

In this article we will talk about how to redirect the output of any terminal command (or console) of

Linux Mint

to a text file.

At times, the output of some terminal commands can be overwhelming. For example, a list of programs that can be updated:

apt list --upgradable

Sometimes, for various reasons, it is more convenient to redirect the output of this command into a text file and view it using a convenient text editor.

And someone just wants to log the execution of any commands in the system or error log. In General, everyone will find use of this opportunity.

Before proceeding to the discussion save the output of terminal to a file, some theory on the standard output streams



If in fact, in Linux has 3 standard streams



- stream is number 0, the standard input stream.


- the stream number 1, the standard output stream.


- the stream 2, stderr,...

Hey all I'm fairly new to this but I want to not hardcode a file to be read in but I want to read it in from the terminal/command prompt. Here is what I have so far, I'm hardcoding the filename in bufferedWriter but how can I make it to where I can do a command such as (java main < in.txt > out.txt). Thanks in advance.

public static void main(String[] args) { String inFile = "in.txt"; String outFile = "out.txt"; if (args.length > 1) { inFile = args[0]; outFile = args[1]; } Lexer lexer = new Lexer(inFile); try { BufferedWriter writer = new BufferedWriter(new FileWriter(outFile)); Token t; while ((t = lexer.nextToken()) != null) { writer.write(t.toString()); writer.newLine(); } writer.close(); System.out.println("Done tokenizing file: " + inFile); System.out.println("Output written in file: " + outFile); } catch (IOException e) { e.printStackTrace(); }...

On Linux systems there are quite a few ways to save command line output to files. Each one operates differently and saves different things.

These commands are useful across all Linux distributions and can even be used on Macs and BSD. The only thing you have to think about is which command is best to get the job done.

Before you dive into the commands, you should know a little history. None of this is specific to Linux. It actually comes from the old Unix operating system developed by Bell Labs. Linux, Mac, and BSD are all Unix-like operating systems that can trace back their family tree to Unix.

One of the core ideas behind Unix was to make everything out of small programs that you can string together to do bigger and more complex things. That’s why you can combine Linux commands to make them work together.

There are a couple of ways to pull together Linux (and Unix) commands and make them work together. The most common one you’ll encounter is the |...

I am trying to run a big script that prompts for answers along the way. I want to run it in verbose mode and thus there will be significant output and I'd like to capture it. Therefore I'd like to run it in a way that allows me to answer the questions as well as sending the output to a file.


While answering you are giving input via file descriptor 0 i.e. STDIN and the program is showing output on file descriptor 1 i.e. STDOUT. As you can see these two are wowking on different file descriptors and manipulating one should not hamper the operation of other.

Note that there is also file descriptor 2 i.e. STDERR normally used for showing error messages.

In you case run the script as:

./ >~/script.out

Now you can provide input answers to the questions of the script via STDIN and the output of the program will be saved in ~/script.out.

You can save the error also e.g. in another file:

./ >~/script.out...

Hello everyone. This topic issues saving the generated error messages (or the command output in general) to a new output file.

This will help you especially if you want to post a topic the Help & Support section. Instead of posting endless screenshots you can copy the output text from the file and paste in in your topic. Sometimes when you get a lot of error messages you need to take 2-3 screenshots however after reading this little guide, you'll be able to just provide the error text and thereby help the people who are trying to help you.

You don't need any additional command line Tweaks from Cydia so we can start right off with the tutorial.

Step 1:

Open up Mobile Terminal / iOS Terminal / MTerminal and chdir into your project folder

Step 2:

To create the command output in another file do following (I recommend you set it to a .txt file for convenient reading on all platforms)

Done. You just created the file Errors.txt in your...

When you run a command in a Terminal window, the output of the command is normally printed to the Terminal, or the screen, so you can read it immediately. You can also print the output of a command to a file, if you want to save it.

Saving the output of a command to a file is helpful if you’re trying to diagnose a problem. To get help from tech support, you may have to run certain commands on your computer and send the results to the support team. This is easy using output redirection on the command line.

Today we’ll cover how to send the output of a command to a text file in the bash shell on Windows, Mac, and Linux.

Note: We’ll be using the Mac Terminal These 6 Awesome Terminal Commands Will Boost Your MacBook in our example, but it works the same way in the bash shell on Linux 40+ Most Used Linux Terminal Commands and in the new bash shell in...

By default, anytime you take a screen capture in Mac OS X, the resulting screenshot file will save to the current users desktop. This makes retrieval very easy and is very appropriate for the average Mac user, but for those who take a lot of screen shots in OS X, they may find their desktop to be cluttered with the screenshot files rather quickly.

An excellent solution is to adjust the default location of where Mac OS X saves captured screen shot files to another location in the file system when Command + Shift + 3 is pressed, this walkthrough will show you how to do that with a defaults command.

How to Change Where Screen Shots Save on Mac

You will need to use the command line to change the save location of screen shots in Mac OS X. Thus, the first thing you’ll need to do is launch the Terminal app from /Applications/Utilities/ to get a prompt.

The general syntax for changing screenshot file location is as follows, note it must be entered on a...

Note version 1.0.3 of the VLC Media Player were used to create these steps. Other versions may differ to varying degrees.

Select Media–>Convert/Save…
Choose the Network Tab to reach the Open Media page. Enter your AVN Stream Destination, including stream type, destination IP and destination port (e.g.: UDP , , 1234) then press Convert/Save.
In the Convert page, enter your Destination file xxx.ts, where xxx is the file name to save, check the “Dump raw input” check box,
Finally, click the Start button when you are ready to save/capture the stream.

Note that in some versions of VLC the “Dump raw input” check box functionality wasn’t working correctly (data wasn’t being saved in its original format). The work around for this, if it occurs, is:
In the Convert page, click the “Edit selected profile” button. It is in the Settings section, to the right of the profile drop down list and looks like a tools button.

There are various files to edit to set up the computer for terminals. If you're lucky, you'll only need to edit /etc/inittab. One does this by editing at the console (or from any working terminal).

Introduction to Getty

In order to have a login process run on a serial port (and the terminal connected to it) when the computer starts up (or switches run levels) a getty command must be put into the /etc/inittab file. Running getty from the command line may cause problems (see If getty run from command line: Programs get stopped to see why ). Getty GETs a TTY (a terminal) going. Each terminal needs its own getty command. There is also at least one getty command for the console in every /etc/inittab file. Find this and put the getty commands for the real terminals next to it. This file may contain sample getty lines for text terminals that are commented out so that all you need to do is to...
