Tmux 3.1: Breaking Free from the Copy Limit
Tired of tmux's copy buffer limitations? Want to paste massive amounts of text without hitting a wall? You're not alone! This article delves into the copy limit in tmux 3.1 and provides a practical solution to expand its horizons.
The Problem:
Tmux, a powerful terminal multiplexer, has a default copy buffer limit. This means you can't copy and paste an unlimited amount of text. When you exceed the limit, the oldest part of the buffer gets discarded.
Scenario:
Imagine you're working on a large log file. You want to copy the entire output to a text editor for analysis. You select the entire file in tmux, press C-b [, and then C-b ] to copy. However, you quickly discover that your paste operation only captures a portion of the file.
Original Code:
By default, tmux sets the copy buffer limit to 1000 lines. You can verify this by running:
tmux show-option -g copy-limit
This will output:
copy-limit 1000
Solution:
The solution lies in modifying the copy-limit option in your tmux configuration file. Here's how:
-
Find your tmux configuration file:
- Linux/macOS: The configuration file is usually located at
~/.tmux.conf. - Windows: The location might differ depending on your tmux installation.
- Linux/macOS: The configuration file is usually located at
-
Open the file:
nano ~/.tmux.conf -
Modify the
copy-limitoption:-
Add or modify the following line:
set-option -g copy-limit 1000000 -
This sets the copy limit to 1 million lines. You can adjust this value to your needs.

-
Save and restart tmux:
-
Save the configuration file and restart tmux:
tmux kill-server tmux
-
Analysis and Insights:
- Performance: Increasing the copy limit excessively can impact performance. A high limit might lead to slow copying and pasting operations.
- Memory: A large copy buffer will consume more memory. Consider your system's resources and balance your needs with potential memory usage.
- Alternatives: If you frequently deal with enormous amounts of text, explore alternative methods like piping the output to a file or using a dedicated text editor with large buffer capabilities.
Additional Value:
- Understanding the
copy-limitoption: Explore other tmux configuration options to customize your experience further. - Beyond
copy-limit: Learn about other tmux features like panes, sessions, and commands for a more streamlined workflow.
