Well if its alright then I may as well as them. I'm curently working through the same worksheet only I have moved onto advanced grep, and there are two questions in it that have me puzzled. Here they are.
Quote:
j) Find out which models of car do NOT contain a digit within their name. Where (line position) within the file are the cars which do have digits within their model name?
m) Find any car model names which include “ee”, without explicitly including “ee”
within your search pattern. Hint: Use curly { } brackets
n) Find out all car models beginning with “B”, and redirect these to a file called
“alpha-carslist.txt”. Append to this file, all car models beginning with “C”. How
many records are in the above file? (Hint: use the “wc -l” command)
And just to show you the layout of how the car list looks like, here are the first few lines, not all of them just in case it seems like too much.
Quote:
Ford:Mondeo:1997:Blue:5
Vauxhall:Vectra:1999:White:2
Seat:Ibiza:1996:Red:4
Peugeot:406:1999:Silver:1
McLaren:F1:1997:Black:2
Skoda:Octavia:2003:Silver:2
Peugeot:206:2000:Red:1
Even with the hints for m & n I'm still having trouble with what comands I should be using, all I know is that I have been using a format such as this for the most recent questions and answers.
Quote:
cat carslist.txt | grep '.*:.*:.*:.*:.*$'
or something similar anyway. Some more help on these would be greatfully appreciated. =-)

NAME
moon-buggy - drive some car across the moon
SYNOPSIS
moon-buggy [-hnsV] [--help] [--no-title] [--show-scores] [--version]
DESCRIPTION
Moon-buggy is a simple character graphics game, where you drive some kind of car across the moon's surface. Unfortunately there are dan-
gerous craters there. Fortunately your car can jump over them!
OPTIONS
The program understands the following command line options.
-h, --help
shows a short usage message.
-m, --mesg
disable write access to your terminal by other users, so your boss can't disturb your game play with the help of "write" or "fin-
ger".
-n, --no-title
skips the title screen.
-s, --show-scores
shows the current highscore list and exits.
-V, --version
prints the program's version to standard output and exits.
KEYS
The moon-buggy is controlled by a couple of keys, which are described near the bottom of the screen. Most important are the following
keys.
SPC, j makes your car jump. The length of a jump is fixed and you can only start a new jump, while the wheels have contact to the ground.
a, l fires the mining laser. The laser is used to remove stones, which may block your way.
q quits the game prematurely. But you still keep your score and may enter the highscore list.
FILES
The following files on your system are related to moon-buggy.
/usr/games/moon-buggy
the moon-buggy executable.
/var/games/moon-buggy/mbscore
the global score file
$HOME/.mbscore
the local score file. This is used, if moon-buggy has no write access to the global score file.
