In terminal a command has a too long output. But when I scroll back I see it is truncated and only the last part is shown. In Gnome-Terminal and Konsole I have this problem. In xterm there's not such problem but I cannot copy the output in xterm.

How can I get the complete output?

You could send the output to a file: command > file.txt (where command is the command you want to run and file.txt is the file you want to save it to) and then view it with gedit file.txt.


Use xclip

cat long.output | xclip -sel clip

If not installed you can do

sudo apt-get install xclip

I know in the xfce4-terminal there is a option to increase the number of lines shown:

Aside from that there is what @Zelda64fan said.

If you don't need the entire output, you could pipe it through less: command | less. This would also save the bother of having to delete the file once you've reviewed the output.

    less output is pretty hard to copy.

In xterm, autocopy on select should be the default. Try triple-clicking then use a middle mouse button (or emulated third button) to paste.

The same should work with other terminals, but you need to manually copy and paste.

There a many, many ways to do this. I like using script in some cases. Type 'script' from a command line to start it before you launch a command from the command line, then hit Ctrl-D to stop. If you don't specify a capture filename, 'typescript' is the default. Everything printed to the screen should be captured in the file.


Save console output into a file:

  1. tee command

tee command - read from standard input and write to standard output and files.

It automatically creates file and save, all the output of cmd ps -ax into a file named as processes_info in the same folder from where the cmd has run.

user@admin:~$ ps -ax | tee processes_info
  1. script command

script command - make typescript of terminal session.

user@admin:~$ script my_console_output.txt

This creates a file named as my_console_output.txt and will open a subshell and records all information through this session. After this, script get started and whatever the console output, it will get stored in the file my_console_output.txt; unless and until the script ends when the forked shell exits. (e.g., when the user types exit or when CTRLD is typed.)

user@admin:~$ script -c "ps ax" processes_info.txt
  • it starts the script;

  • creates the file processes_info.txt;

  • stores the console output into the file;

  • end (close) the script.

    Other example:

     script -c 'echo "Hello, World!"' hello.txt
  • script -c "rails runner -e development lib/scripts/my_script.rb" report.txt helped me to capture a Rails runner script's very-very long output easily to a file. I tried using redirecting to a file but it got written only at the end of script. That didn't helped me because I had few interactive commands in my script. Then I used just script on my and then ran the rails runner in script session but it didn't wrote everything. Then I found this script -c "runner command here" output_file and it saved all the output as was desired. This was on Ubuntu 14.04 LTS Commented Apr 20, 2018 at 15:05
