Reread "Relativity" chapter and took notes regarding Lorentz Transformations on distance, time, momentum, and energy. 

Also took notes on particle lifetime, Heisenberg Uncertainty Principle, Breit-Wigner, and rapidity.

Created testscript.tcsh using the emacs. Had trouble running it at first because I mistook the "#!/bin/tcsh" part of the tutorial as a comment rather than part of the script.

The script is able to searches all directories for files containing the input word. Didn't work prior to modding the script with "chmod +x testscript.tcsh"

"+x" can be replaced with "700" for owner use and edit only, while "755" will allow user to use and edit as well as allow others to use but not edit. "777" will have no user restrictions

whatsoever.

Created a homesearch.tcsh script. At first had problems by forgetting to add "#!/bin/tcsh" again. 

Input "touch testfile" creates a file on the current directory called "testfile".

Ran "./homesearch.tcsh testfile" and created a .txt file within the directory called "homesearch_testfile.txt" which contained the directory location of the "testfile" file.

Created github account and linked it with the cluster following the steps from the tutorial.

Created a repository called "HONRPHYS" on github website. On hepcms, created subdirectory called "gittest" and was able to complete the following steps from the tutorial:

1. echo “# HONRPHYS” >> README.md

2. git init

3. git add README.md

4. git commit –a -m “first commit”

5. git remote add origin https://github.com/your_github_user_name/HONRPHYS.git

Step 6, "git push –u origin master", produced problems saying it couldn't connect.

Learned "grep" command in Linux. Created file "greptest.csh" to serve as a grep function that would search files within the current directory for a given word from the command line.

Had problems creating the file at first:

- Instead of saving it as a .tcsh file, as in with the "find" command, "grep" is saved as a .csh file instead

- Instead of using ""*$1*"" as my variable, as in the "find" command, "grep" uses ""$1"" instead

- Instead of using "~" for the current directory, as in the "find" command, "grep" uses "*" instead

Managed to git push to origin master. Instead of adding a "HTTPS" origin, a "SSH" origin should be added instead because SSH keys were used.
