description: Exploring /usr/bin with available tools in the Linux system
---

even after uing linux for 4 years already, looking at /usr/bin is kinda scary: 1900 apps on kubuntu distro...
So after some fiddling in man manpages found out that you can get small explanation on executables (if any) and stiched this thing together:
```sh
ls -x /usr/bin/ | xargs man -f | less
```
So now I can read all about installed bins on my devices. Neat!

And if I have to find if some apps downloaded that fit my keywords I can grep on the result of xargs: 
```sh
ls -x /usr/bin/ | xargs man -f > /tmp/binsinfo && cat /tmp/binsinfo | grep locale
```

And also don't forget to add redirection do null so it doesn't show errors from man after grep: 
```sh
ls -x /usr/bin/ | xargs man -f > /tmp/binsinfo 2>/dev/null && cat /tmp/binsinfo | grep locale
```
