7 Time-Saving Linux Commands to Boost Your Productivity

Some Linux commands can significantly streamline your work in the command line, enhancing efficiency and productivity. Here are seven valuable commands that can save you time.

1. Simplifying Man Pages with tldr

The tldr command presents simplified pages to help you quickly understand how to use various commands without sifting through lengthy manuals. For instance, to see how to use the date command, you can type:

$ tldr date

This will summarize the command’s functionalities and provide practical examples.

2. Analyze Disk Usage with ncdu

The ncdu command offers an intuitive interface for looking at disk usage, allowing navigation with your keyboard. After running ncdu, you might see a structure like this:

ncdu 1.20 ~ Use the arrow keys to navigate, press ? for help--- /home/shs --------------------------------------------------------------------  114.6 MiB [#################] /.cache   ...

3. Synchronize Data with rsync

The rsync command is essential for efficiently syncing files and directories. To copy a directory, you can use:

$ rsync -r bin /tmp

This copies the local bin directory to the /tmp location.

4. Monitor Progress in a Pipe with pv

The pv command (Pipe Viewer) allows you to watch the progress of data being transferred through a pipe. For example:

$ cat largefile | pv | gzip > largefile.gz

This command displays the transfer speed and completion time.

5. Generate Random Text with fortune, rev, and shuf

The fortune command generates a random quote, whereas rev reverses the text provided to it:

$ fortune | rev

shuf randomizes the lines from a file:

$ shuf names

Every execution yields different output.

6. Monitor Changes with watch

The watch command repeats a command at intervals and highlights output changes. For example:

$ watch -d free -m

This command checks memory usage every two seconds.

7. View Directory Structure with tree

The tree command displays files and directories in a visually appealing tree-like format:

$ tree bin

This gives you a clear understanding of your directory’s structure.

Conclusion

These commands can simplify command-line tasks, making your work more efficient. Consider creating aliases for more complex commands to enhance usability even further.
