so many keys and commands to take in. command promts.
Ive learned the vi text editor realy is the Best text editor on the planet. entering text is inspiring. may need more practice
This is a sample format for a dated entry. Please substitute the actual date for “Month Day, Year”, and duplicate the level 4 heading to make additional entries.

played with commands. Found out how to move files around
The shell is the traditional user interface If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:
main, center, top, start directory.
If you want to demonstrate something on the command-line, you can do so as follows:
lab46:~$ cd /
A file system structure. same as the file folder, which is a visual aid for non-unix users. If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:
a set of processes chained by their standard streams, so that the output of each process (stdout) feeds directly as input (stdin) to the next one.
If you want to demonstrate something on the command-line, you can do so as follows:

calender- displays time, date, country codes.
Identification and definition of the chosen keyword. Substitute “keyword” with the actual keyword.
If you want to demonstrate something on the command-line, you can do so as follows:
lab46:~$ cd src lab46:~/src$ gcc -o hello hello.c lab46:~/src$ ./hello Hello, World! lab46:~/src$
The tee utility is one of my personal favorites and is very simple. The command is intended to be used in a pipe to capture the standard output of another command and display it on the screen, as well as copy it to a file. In the following example, the directory listing is displayed on the screen, and also copied to the file dir.txt. Using cat to type out the dir.txt file shows that it contains the same information that was displayed on the screen.
$ ls -l|tee dir.txt total 141 -rwxrwxrwx 1 mjb group 16850 Apr 12 16:13 SMALL01.DOC -rwxrwxrwx 1 mjb group 14881 Apr 12 20:51 SMALL02.DOC -rwxrwxrwx 1 mjb group 17758 Jun 13 01:29 Small03.doc -rwxrwxrwa 1 mjb group 12791 Jul 12 22:44 Small04.doc -rwxrwxrwx 1 mjb group 4232 Jun 12 00:03 Smallxx.doc drwxrwxrwx 1 mjb group 0 Jul 12 21:25 docs -rwxrwxrwx 1 mjb group 261 Jun 13 01:08 hello.cbl -rwxrwxrwx 1 mjb group 184 Jun 13 00:59 hello.txt -rwxrwxrwa 1 mjb group 343 Jul 12 21:32 mver -rwxrwxrwa 1 mjb group 83 Jul 12 19:52 sh_histo -rwxrwxrwx 1 mjb group 455 Apr 12 18:10 simpmenu -rwxrwxrwx 1 mjb group 600 Apr 12 18:39 simpmenu.txt -rwxrwxrwa 1 mjb group 17 Jul 12 22:24 sleepy -rwxrwxrwx 1 mjb group 189 Jun 13 01:13 smallfry.txt $ cat dir.txt total 141 -rwxrwxrwx 1 mjb group 16850 Apr 12 16:13 SMALL01.DOC -rwxrwxrwx 1 mjb group 14881 Apr 12 20:51 SMALL02.DOC -rwxrwxrwx 1 mjb group 17758 Jun 13 01:29 Small03.doc -rwxrwxrwa 1 mjb group 12791 Jul 12 22:44 Small04.doc -rwxrwxrwx 1 mjb group 4232 Jun 12 00:03 Smallxx.doc drwxrwxrwx 1 mjb group 0 Jul 12 21:25 docs -rwxrwxrwx 1 mjb group 261 Jun 13 01:08 hello.cbl -rwxrwxrwx 1 mjb group 184 Jun 13 00:59 hello.txt -rwxrwxrwa 1 mjb group 343 Jul 12 21:32 mver -rwxrwxrwa 1 mjb group 83 Jul 12 19:52 sh_histo -rwxrwxrwx 1 mjb group 455 Apr 12 18:10 simpmenu -rwxrwxrwx 1 mjb group 600 Apr 12 18:39 simpmenu.txt -rwxrwxrwa 1 mjb group 17 Jul 12 22:24 sleepy -rwxrwxrwx 1 mjb group 189 Jun 13 01:13 smallfry.txt $

Can i copy the game directory and past it in my closet.
Can the game directory be copied and pasted into the a closer directory, such as, my closet?
Collect information and resources (such as URLs of web resources), and comment on knowledge obtained that you think will provide useful background information to aid in performing the experiment. The following commands are needed. $ man cp $ man ls $ pwd $ ls $ cp $ cd
I belive that you can move or copy the game directory to another of your chosing. in turn bring an easy and quick solution to over exploitation of the cd command. While shorting the time it takes to play a simple game. Based on what you've read with respect to your original posed question, what do you think will be the result of your experiment (ie an educated guess based on the facts known). This is done before actually performing the experiment.

work day. opus,projects,unix.
Project on puzzle box is done for the most part. working on next.
After reading up on bash scripting. I made two programs displayed on a web page. while exploring such avaneus I made one from scratch. leaning to keep track of typos is the hard part.
This is a sample format for a dated entry. Please substitute the actual date for “Month Day, Year”, and duplicate the level 4 heading to make additional entries.

crrerats FIFO's (also called “named pipes”) with the specified names.
aseIf you want to demonstrate something on the command-line, you can do so as follows:
a term created by programmers that state mandates a programmer, or comp user of UNIX/ Linux based systems must at least try to find a answer to their problems. This must be done before asking a more experienced programmer.
R- read T- the F- **** M- manual
A metacharacter is a character that has a special meaning (instead of a literal meaning) to a computer program, such as a shell interpreter or a regular expression engine.
The export command is used to define the variable as one that subshells (shells spawned from the original) should inherit.
rlott@lab46:~$ export PAGER rlott@LAB46:~$
a command built into the bc program. this command is used to display the output of mathematical computations in binary, octal, base 10, etc.
If you want to demonstrate something on the command-line, you can do so as follows:
A FIFO special file is similar to a pipe, except that it is created in a different way. Instead of being an anonymous communications channel, a FIFO special file is entered into the file system by calling mkfifo.
print- command
files, space for storage of more data, directories, programs.
Mainly the 'cli' set on a visual screen for user interface.
This directory contains the commands and utilities that you use day to day. These are executable binary files aka bin.
standard terminal emulator for the X Window System
Scripting with bash and programming concepts. using bash in the vi editor to write the program code. successful execution of the {chmod} command in order to change the file format from rw, read-write. To a executable format via program file.
after a well developed presentation on the inner working of bash, vi, aka vim, and the method of programming. One could have a assignment that leave the class to explore and change the outcome or multiple outcomes of the program.
my irc chat bot was deleted by mistake so here is a quick dummy program. Lable: loop objective of program- take the $who command and pipe to $less for display.
change to program: The who command piped into the vi text editor.

If i were a little more froggy, the program could be modified to pop up the same as the $motd to display who is on the sever. MAKING LIFE EASY.
can you have the command
:date +%s be placed into a loop script to constantly count up to 23458789… in unix time?
vim, internet, linux, instruction from course booklet. google - most searching was based off this site.
Run the bash script while looking for syntax errors. If none the program should be a success. will the script run or will it be a dodo
The program runs. yet a error 4 line for is spammed while counting. why!!!
#!/bin/bash while true do date= `date +%s` echo "$date" sleep 1 done echo `date +%s`
Based on the data collected: The program did count, forward in time, but the loop applied in the scripting has a continual count time. a error for line 4 was part of the display. all together, much of this experiment was a success.
I need to study more about scripting and program concepts. small errors and the ability to notice are my weak points. I still see bash scripting more fun and easy for windows command line. it“s a little more manual like a standard car.
can $who command be placed into a text file
google.com
If the who command can be placed in the less program, than is should work for the $vi text editor.
By simply changing the command named in the syntax out with the vi text editor. The process should be as successful as the first run with the less command.
#!/bin/bash when= who | vi echo "have you seen my base ball" echo $WHO echo "yes or no" exit 0
first run
lab46:~$ ./test Vim: Warning: Input is not from a terminal Vim: Error reading input, exiting... Vim: preserving files... Vim: Finished. have you seen my base ball
Based on the data collected: The process is different from the last.
Changes must be made to the program in order to have it work. the text file may need additional commands to fulfill the process applied.
