15 Linux commands I’ve used most recently and love in general
- Linux provides extreme flexibility and options to configure everything to your liking. It also provides tens of thousands of commands (based on the number of man pages).
- less provides an efficient way to view and navigate large files without loading the entire file into memory. It is especially useful when working with large system logs or data files.
- Disk space can quickly fill up, especially on systems with large media files, backups, or logs. Instead of manually checking file sizes across directories, you can use find to locate large files that might be hogging space. It’s especially helpful when performing system maintenance or managing disk space on servers.
- zgrep allows you to search within compressed files directly, instead of decompressing these files every time you need to search for something inside them.
- When analyzing logs or large files, sometimes you only need to see the first or last few lines, such as in cases of debugging or inspecting recently added log entries. head and tail make this quick and efficient.
- When working with configuration files, scripts, or large datasets, you may need to replace certain text patterns across multiple files. Instead of manually opening each file, sed automates the text replacement process in bulk.
- grep allows you to search through multiple files quickly and efficiently, making it ideal for debugging or searching through large codebases, logs, or configuration files.
- Log files and datasets are often structured in columns (e.g., CSV files or tab-separated data). awk allows you to extract specific columns and apply filters based on conditions, making it ideal for data analysis and report generation.
- convert from ImageMagick makes it easy to convert images from one format to another, such as converting .png files to .jpg, or resizing images for web optimization.
- xkill is a command that turns your mouse cursor into a crosshair (X), and you can click on any window to immediately force-close it, making it easy to kill problematic windows.
