I think the database was better than the other two, but I can never trust my instincts when it comes to school, so I really don't know. All of them had some questions I didn't really know how to answer, so I just answered SOMETHING hoping to be near what they wanted
even one of the two teachers we have in databases struggled with one of the tasks on that exam (we asked him about it when it was finished) I left after half an hour when he still hadn't come up with an answer

I was a little afraid to be around computers when i was in high school. Mainly because i didn't know anything about them and instead of trying to learn; I was afraid of looking stupid.
But i was just a kid then.
But i was just a kid then.
Of course, I grew up in rough neighborhoods where just getting thru the day without getting beat up was a challenge. After Windows came out, i started looking at computers. Then I got to the point where I wanted to learn how theyWork. Since I am a long haul truck driver I can't go to school to learn about them. So I buy books from B &N or B Dalton and learn on my own that way. And by talking to people who know about them too.

hmmmmmmmmmm, my machine has lots of new shortcuts not that I have W7 :S I lost everything I just wrote -,- aaaanyway...
we just started this week, so I'm trying and failing and learning
I am to write a bash script that:
takes two command line parametres (these are used to search a place AND a course/ class from a list in a file)
returns the lines that have a match in both paramtres
counts and returns number of lines/matces found
----
bash works something like this:
###
#!/bin/bash
echo "prints something to screen" # prompts user to give computer input
read varname # read reads the input and makes whatever I put in place of varname point to it (like var="something")
echo "you typed $varname" # prints you typed ..and whatever the user typed in as input
# also var=$(($a+$b)) gives var the value of variables a+b and can then be called as $var

duuuuuuuuuuuuuuuuuuuuuuuuh!
it was only because the manuals were confusing me. It says over and over again that you have to put strings in " " to make the shell use the whole line (otherwise it will only take the first word) but of course if i use the search command with " " it will search for "word" not word.....
echo 'Dont enclose seach criteria in ""''
echo
echo "Type place name"
read place
echo "Type class name"
read class
if [ -z "$place" ] || [ -z "$class" ]; then # checks if they have zero value
echo "You must enter both a place and a class name!"
echo "Finishing! try again"
exit # quits
fi # end of if function
grep "$sted" navneliste-1.txt | grep "$studie" # search for whatever was entered in the variables in the textfile called navneliste-1
# this will return all lines matching BOTH criteria
echo "Number of hits: "
grep "$sted" navneliste-1.txt | grep "$studie" | wc -l # returns number of hits given in search
" the | pipes the answer of the first function into the next one

You make my job very easy. Each time you have a problem, and I want to have a look to help you, you find the solution yourself!
I'm great, not?

tried to figure out how on earth I am supposed to use cat or a for loop in a search
8 count=0
9
10
11 while read name
12
13 do
14 count=$((count + 1))
15 echo $navn
16
17 done < navn-1.txt
18
19 echo " "
20 echo "found $count names"
21 echo " "
___________
6 # v.1.0
7
8 teller=0 #count
9 IFS=$'\n'
10
11 for navn in $(cat navn-1.txt)
12
13 do
14 teller=$((teller + 1))
15 echo $navn
16
17 done
18
19 echo " "
20 echo "Det var $teller navn tilsammen"
21 echo " "
=======================
I am supposed to use one of those to change another assignment I did where I search a text file for two inputs, then print the lines matching both inputs
but I can't find a way to use it, because whatever argument i put behind cat, the bash shell expects to be a filename (or so it seems)

This is the file I am supposed to incorporate it into somehow:
(Am of course not looking for someone to do my homeowrk, but I could neeed an example of how to use _ for....in....cat ....stuff in this setting)
echo
echo "type name of place"
read sted #read place
if [ -z "$sted" ]; then
echo "no input given!"
echo "quit"
exit
fi
echo "search for course"
read studie # course
if [ -z "$studie" ]; then
echo "must have both name and course!!"
echo "quit"
exit
fi
grep "$sted" navneliste-1.txt | grep "$studie" # prints the matching lines (grep searches and prints lines in the text file navneliste-1.txt
echo "Antall treff: "
grep "$sted" navneliste-1.txt | grep "$studie" | wc -l # wc -l counts number of lines matching the seach
dato=$(date +%F) # date var
grep "$sted" navneliste-1.txt | grep "$studie" >"$sted$studie$dato".txt # save to file with varibales as filename
grep "$sted" navneliste-1.txt | grep "$studie" | wc -l >>"$sted$studie$dato".txt # add count to same file
