| − | [[Cueball]] has messed up his {{w|Linux server}} | + | [[Cueball]] has messed up his {{w|Linux server}}, {{tvtropes|WalkingTechbane|apparently not for the first time}}. [[Megan]] offers to take a look at the PC and types in "ls" — a basic command that lists the files in the current directory. The computer returns a bizarre error message — it trips over one of the simplest commands, indicating that Cueball's system is messed up. ''Really'' messed up. |
On Linux, most commands are executables usually found in either /bin or /usr/bin. The /usr/share folder, on the other hand, is where "architecture-independent shared data" is stored. Adobe is a software company that produces Acrobat, Photoshop, and a wide range of other software for manipulating work revolving around a 2D canvas. "android_vm" would likely be a virtual machine for Android. The .jar extension suggests a Java-language program. None of the above items are related to the command "ls", nor do they have anything to do with each other, with the semi-exception that Android is based on Java. Executables should also never be found within /usr/share or within directories named "example" or "doc" - indeed, by default Linux does not even look in the /usr/share directory for items that can be run unless the user {{w|PATH (variable)|tells it to do so by changing the $PATH variable}}. The presence of "ls.jar" within a folder called "android_vm" suggests Cueball was attempting to boot up a virtual Android device, but somehow wound up directing the Linux server to use the executable files meant for the virtual system instead of the correct ones in /bin or /usr/bin. | On Linux, most commands are executables usually found in either /bin or /usr/bin.
