The chmod +x command sets the executable bit on the AppImage. I find that small checkpoint useful because it concerns whether Linux can run the file, not the sketch. Bring the sketch you want to write into focus. Then see where the desktop IDE fits in getting it ready for a board. What Arduino IDE

With mkdir -v -p project/src/assets, each created directory gets its own line. I love how that output makes each new level visible. Choose the directory path you want ready, either beneath your current directory or starting at the filesystem root. See what mkdir creates at that resolved location. What mkdir creates On a GNU Coreutils

With echo ‘mississippi’ | tr -c ‘s’ ‘z’, the final z replaces the line break, so the prompt appears on the same line. I couldn’t resist digging into why tr treats that ending as part of the transformation. Follow tr’s character transformation from standard input to standard output. Choose the operation by deciding which characters

An /etc configuration file describes the host, not a user’s personal settings. I was surprised that such a plain path carries that machine-wide role so clearly. You’ll learn to distinguish host-specific settings from data intended to be shared. You can see how the FHS assigns roles to familiar paths. What the FHS standardizes The Filesystem

When an unwanted command sits at history number 262, deleting an earlier entry can move it to a new number. I’m fascinated by that shift: Bash numbers positions in a live list, not permanent command identities. Have Bash display the numbered entries in its active list. See how the session list relates to the file

df -h /var can show the filesystem mounted at /, not a size for /var itself. I’m intrigued by how a path can lead to a mount’s space report instead of a directory total. You’ll get a clear sense of what each capacity column measures. Turn to df’s report and read its capacity figures alongside

In the redirection example, exec-output.log receives both output streams, then “back on terminal” appears on the terminal. I appreciate how the file descriptors make the shell’s output destinations visible. You’ll connect that result to the scope of Bash’s builtin, rather than treating exec as a command that always launches a program. You can see whether

An ARM image on a distro’s download page can change the shortlist when your project targets that hardware. I value architecture as a concrete part of the distro choice, beyond desktop appearance. Move from the hardware detail to the distro’s own tradeoffs. Compare the software it provides with the pace of its updates. A distro

`ip route get 127.0.0.1` reports a local route through `lo`, not just the address assigned to that interface. I like that `ip` can answer a destination question without making an address listing do double duty. Pin down the network question you need answered. Then choose the `ip` object that fits it. What the ip command

Manjaro stages packages through its own repositories, while EndeavourOS describes a terminal-centric setup. I like that these differences make the desktop choice a question of maintenance as well as appearance. Your comparison gets clearer when you know which choices belong to the distro itself. Set those choices beside what Arch provides. What makes a distro
