UNIX for Dummies Questions & Answers

I tend to agree with Ikon's comments above. Some people might view them as a bit tough, but he has a good point.

glev2005,

Experts here are not your private employees to do you work for you. They help because they are generous with their time and knowledge. You have a responsibility to actually do your share of the work and not simply ask people here to do all your work for you.

Ok, well just to clarify.. I am not a student, this is not a school project.. I am trying to do some work on a Macintosh Network, and I use BASH, which I am far from an expert in, to do so for the most part. I hear all of your comments, but it is much better to hear them from a moderator, and not some opinionated user who really should just move on if he doesnt like my question. I know quite a lot about some subjects, and am happy to impart knowledge to people of all skill levels, and if i'm not, then I dont and I keep quiet.


That being said, I have narrowed down to getting each number on a separate line, I now have to take the numbers on each line and add them up, I suppose using expr.. Can I please have some help with this?

also, how do i create code tags? <code> ? </code>

Code:

[code]
my code, data file whatnot goes here
more of the whatnot
[/code]

here're a number of ways to add numbers from a file (one number per line):

Code:

echo `sed -e 's/$/+/' file.txt` 0 | bc
OR
awk '{sum+=$1} END {print sum}' file.txt
OR
echo `tr '\n' '+' < file.txt` 0 |bc
OR
paste -sd+ file.txt |bc
OR
printf "%d\n" $(( `tr -s '\n' '+' < file.txt` 0 ))

IF all the lines were in one file you could do the following to could the second colum.

Code:

# cat server.lst
server_a 2
server_b 4
server_c 1

#  awk '{s += $2} END {print s}' server.lst
7

If there are separate files with just a number in them:

Code:

# cat servera.server
1

# cat serverb.server
9

# cat test.sh
declare -a FILES
FILES=`ls *.server`
COUNT=0
for PRT in ${FILES[@]}
do
        UPD=`cat $PRT`
        COUNT=$(( $COUNT+$UPD ))
done
echo "Total: $COUNT"

# sh test.sh
Total: 10
