 **Five cool Linux command-line utilities you probably never heard of**. All these tools can easily be installed via your native package manager (typically `apt install xxxx`). # Axel Almost every Linux Admin knows about **wget**. Have you heard of **axel** though? Axel works just like wget but uses download segmenting to dramatically speed up large file downloads. Axel can also auto-resume your download if stops before it are complete and you need to restart it. https://i.imgur.com/dfugs0G.png https://i.imgur.com/BWNlEl1.png # ncdu **ncdu** is a really useful but not very well known utility to interactively identify where the space on your file system is being used. On Windows there is a tool called WinDirStat, this is pretty much the same thing but for Linux command-line. You can move around your file system and view the largest files in any directory interactively. https://i.imgur.com/q8sqn3M.png Need to find out what is using up all your disk space, this is far more powerful than **du**. # tcptrack **tcptrack** is a really cool utility for monitoring active network connections in real-time. While similar to **netstat** this will give bandwidth usage and is updated in real-time.  <sub>[source](https://linoxide.com/monitoring-2/network-monitoring-tools-linux/)</sub> # shellcheck Think of **shellcheck** as linting for sh scripts. Shellcheck will scan a sh script and let you know where you can improve your scripts and find errors.  <sub>[Source](https://github.com/koalaman/shellcheck)</sub> # nethogs While **nethogs** is very similar to **tcptrack**, instead of giving you just ip/port information it will actually tell you what processes and scripts are using up bandwidth. This can be extremely helpful in troubleshooting a problem.  <sub>[Source](https://unix.stackexchange.com/questions/91055/how-to-tell-if-mysterious-programs-in-nethogs-listing-are-malware)</sub>
