Introduction

This is my change. I was going to edit this later. When I was away from the college but I didn't because of video games and laziness, sorry.

Learning about the xwit, xte, and xwininfo commands. Using both xwit and xte we can warp the cursor around the screen to various locations. Using the xte command we can also produce “fake” input with the keyboard and mouse allowing for functional mouse clicks and various keyboard button presses. We've been learning how to use the mousemove command in xte allowing us to draw in the mtpaint program. Learned that putting the & at the end of a command will make it run in the background giving you your command prompt back which is what you had to do when running mtpaint in a program as when you run the program normally it occupies your terminals focus.

Learned that greping isn't just based on files (i know i thought i could only grep from files) now using grep i can just search for specified strings in lines. Additionally now since im not dumb and think grep is only for files i can use regex a significant amount more to help to find general but specific information.

Learned that once bc has the decimal points even if you change the scale it will keep the decimal points, i had to actually cut the value out so it wasn't a float point

So I've learned that if you just make a file executable and you put actual lines of the command line in it, it will run which is coll even though its not the most advanced way to code it is pretty easy and will allow me to just write what I want a program to do without using another syntax that I am already using on the command line, and then you can just run it by doing ./filename. I learned how cut works using its fields if you specify field and then give it the delimiter of anything you can separate by words using space as a delimiter and you can do it by letter by using nothing, on the other hand, I learned how the opposite function paste which allows you to paste together anything you want you can string words into sentences by using the delim of space or you can just paste images together like the puzzle box by just using the delim of nothing We learned the value of vim somewhat although we didn't get the chance to see anything advanced as we had a snow day.

Learned that pipes | as written in the CLI are taking the output from one command and transferring it into another command like this cat file| wc -l This is taking the print to stdout (the screen) and piping it to the word count function to show how many lines are in the file file Learned about how archives and encoding/ decoding works such as using uuencode will take some plain text sentence or sequence and encode it so that you can no longer read it and to get it back from that form you have to uudecode it back into plain text. Additionally, gzip zip and xz tar and bzip2 are all archiving utilities and that they all take one or more files and put them into one file. I learned (accidentally) that if you don't specify the .tar file extension for the first file when archiving using the utility it will just place all contents of the files to be archived in the first file in the sequence of files to be archived without changing the file extensions on. Learned the rev will reverse the order of all of the characters in a line of an entire file allowing for the file to be backwards line by line and that tac will reverse the line order of any file such that the first lines will be at the bottom and the last lines will be at the top. I learned how easy it was to copy stuff with the cp command as long as you knew the absolute path of the item to be copied and the place you want it copied to you can just say cp /filelocation/ansotherfilelocation/additionallocation/file /yourplacetobecopiedto/anotherfolderyay/finalfiledestination and it will sopy from the first file into the second file name no problem cat will display the contents of any file(s) you give it Our spellbook is rapidly swelling with so many new and exciting spells and now we can channel one spell into another to make it even more powerful than before. The Archmage Matt is teaching us well and will help us develop our own skills and specialties.
