I installed some packages on my Ubuntu and this generated a lot of data on the terminal screen that I would like to save to a text file. Is it possible to do this natively, without the help of any external software?

Introduction
If you are an Ubuntu user, you might have encountered a situation where you need to save the output of a command or a log file to a text file. Sometimes, the output is too long to be viewed on the terminal screen, or you might want to keep a record of the output for future reference. In this blog post, we will discuss how to save the content from the Ubuntu terminal to a text file.
Using the ‘>’ symbol
The simplest way to save the output of a command to a text file is by using the ‘>’ symbol. The ‘>’ symbol is used to redirect the output of a command to a file. For example, if you want to save the output of the ‘ls’ command to a file called ‘filelist.txt’, you can use the following command:
ls > filelist.txt
This command will save the output of the ‘ls’ command to a file called ‘filelist.txt’ in the current directory. If the file does not exist, it will be created. If the file already exists, its contents will be overwritten.
You can also append the output of a command to an existing file by using the ‘>>’ symbol instead of the ‘>’ symbol. For example, if you want to append the output of the ‘ls’ command to a file called ‘filelist.txt’, you can use the following command:
ls >> filelist.txt
This command will append the output of the ‘ls’ command to the end of the ‘filelist.txt’ file. If the file does not exist, it will be created.
Using the ‘tee’ command
The ‘tee’ command is another useful command that can be used to save the output of a command to a file. The ‘tee’ command reads from standard input and writes to both standard output and a file. For example, if you want to save the output of the ‘ls’ command to a file called ‘filelist.txt’ and also view the output on the terminal screen, you can use the following command:
ls | tee filelist.txt
This command will save the output of the ‘ls’ command to a file called ‘filelist.txt’ and also display the output on the terminal screen.
You can also append the output of a command to an existing file by using the ‘-a’ option. For example, if you want to append the output of the ‘ls’ command to a file called ‘filelist.txt’ and also view the output on the terminal screen, you can use the following command:
ls | tee -a filelist.txt
This command will append the output of the ‘ls’ command to the end of the ‘filelist.txt’ file and also display the output on the terminal screen.
Using the ‘script’ command
The ‘script’ command is a powerful command that can be used to save the entire terminal session to a text file. The ‘script’ command records everything that appears on the terminal screen, including input and output. For example, if you want to save the entire terminal session to a file called ‘session.txt’, you can use the following command:
script session.txt
This command will start recording the terminal session and save it to a file called ‘session.txt’ in the current directory. To stop recording, you can type ‘exit’ or press ‘Ctrl-D’.
The ‘script’ command can be very useful for debugging purposes or for keeping a record of a long terminal session.
Using the ‘logsave’ command
The ‘logsave’ command is another useful command that can be used to save the output of a command or a log file to a text file. The ‘logsave’ command works by running a command and saving its output to a file. For example, if you want to save the output of the ‘ls’ command to a file called ‘filelist.txt’, you can use the following command:
logsave filelist.txt ls
This command will run the ‘ls’ command and save its output to a file called ‘filelist.txt’ in the current directory.
The ‘logsave’ command can be very useful for saving the output of a command or a log file to a text file without having to redirect the output manually.
Using the ‘xclip’ command
The ‘xclip’ command is a useful command that can be used to save the output of a command to the clipboard. The ‘xclip’ command works by reading from standard input and copying the contents to the clipboard. For example, if you want to save the output of the ‘ls’ command to the clipboard, you can use the following command:
ls | xclip
This command will save the output of the ‘ls’ command to the clipboard. You can then paste the contents of the clipboard to a text editor or any other application that supports pasting.
The ‘xclip’ command can be very useful for quickly saving the output of a command to the clipboard without having to save it to a file first.
Conclusion
In this blog post, we discussed how to save the content from the Ubuntu terminal to a text file. We covered several methods, including using the ‘>’ symbol, the ‘tee’ command, the ‘script’ command, the ‘logsave’ command, and the ‘xclip’ command. Each method has its own advantages and disadvantages, and you should choose the method that best suits your needs. By using these methods, you can easily save the output of a command or a log file to a text file for future reference.
Yes, it is possible to save the content from the Ubuntu terminal to a text file. There are a few different ways you can do this:
- Use the
tee
command:
command | tee file.txt
This will run the command
and save the output to both the terminal and to the file file.txt
.
- Use the
script
command:
script file.txt
This will start a new terminal session that records all terminal output to the file file.txt
. When you are finished, type exit
to stop the recording and close the terminal session.
- Use the
>
operator:
command > file.txt
This will run the command
and save the output to the file file.txt
, overwriting the file if it already exists.
Note that these methods will only save the output of the command, not the command itself. If you want to save both the command and the output, you can use the history
command to view your recent terminal commands, and then use the >
operator to save the output to a file:
history > commands.txt
This will save a list of your recent terminal commands to the file commands.txt
.
Here are a few more things you might find helpful when saving the content from the Ubuntu terminal to a text file:
- You can use the
>>
operator instead of the>
operator to append the output of a command to the end of an existing file, rather than overwriting it. For example:
command >> file.txt
You can use the tee
command to append the output of a command to a file, rather than overwriting it, by using the -a
flag:
command | tee -a file.txt
If you want to save the output of multiple commands to a single file, you can use the ;
operator to separate the commands, like this:
command1; command2; command3 | tee file.txt
If you want to save the output of a command to a file and also keep a copy of the output in the terminal, you can use the tee
command with the >
operator, like this:
command | tee >(cat) file.txt
This will save the output of the command
to the file file.txt
, and also display a copy of the output in the terminal.
I hope this helps! Let me know if you have any other questions.
It is also possible to write only the output of each command to a text file, for example:
YourCommand > OutputFile.txt
If you want to append data:
YourCommand >> OutputFile.txt
If you want to show errors with stderr:
YourCommand &> OutputFile.txt
or this to append:
YourCommand &>> OutputFile.txt
If you want the contents of everything that is going on, stderr, shell in a file, use this:
YourCommand 2>&1 | tee OutputFile.txt
If you want to show only the output, remove the 2, like this:
YourCommand >&1 | tee OutputFile.txt
I hope it helps!
Yes, absolutely.
If you want to save everything that appears on your shell screen, you can use the script command.
The “script” command saves everything that happens on your screen in a text file, until you enter the exit command.
That way, everything you see on the screen will also be saved in the text file. As long as you have activated the script command before executing any command you want to write to your text file.
$ script ~/outputfile.txt
Script started, file is /home/petermiller/outputfile.txt
$ command1
$ command2
$ command3
$ command4
$ command5
$ exit
exit
Script done, file is /home/petermiller/outputfile.txt
See how the exit command finishes recording the text.
When you want to check the data for each command, use the following:
cat ~/outputfile.txt
Enjoy! ;)
