Doesnt seems like many of you very intressdid in this thread.
Anyway i come up with an solution of it happends to have the same problem.

Under %post in your kickstart server config:
#!/bin/sh...

first of all i am aware of that /etc/hosts dont contain the actually ip adress but hostname, its an example.

Another way to solve this problem is to set variables i guess...

#!/bin/sh
touch...

You dont have to know the answer, more or less i want to know if it is possible.
But if you got any tip on HOW TO i wouldnt cry either :)

Hello Linux gurus!

Ive got a RedHat EnterP. 4 kickstart server that is also running RedHat EnterP 4.

Hello there!

Any kind of help would be very much appreciated, got deadline today.

I need to cut out first 3 letters and...

Got a problem with a loop that do this for each line:
a=$(( cost + $( awk ' { print $2 } ' file) ))
awk ' $2 ~ "^[0-9]" && $2 > 0 {$2='$a';print} ' file

#!/bin/sh
cost=30
for, until, while? ...

Thank you for the help mate.

Got it to work like this:
cost=30
a=$(( cost + $( cut -c23-26 5) ))
echo $a

It does work if the f2 is actually on field 2 but its is on field 23 so to speak.
File do look like this:
Col10 51 Col23 11

...

I really cant understand whats wrong with this:

File looks like this:
55 11

Code:
cost=30
a= cut -c9-12 File
let a=${a}+${cost}
echo $a

The answer echo should echo 11+30(cost)...

awk ' $2 ~ "^[0-9]" && $2 > 0 {$2=20;print} ' file

This worked when i removed +$

Thank you for the answer.
It seems to work but to the actually file....

I get no output at all to the actually file but if i do a file like the example it works..
The actually file looks like...

This seems to work so far:

awk ' /[0-9]/ {print} ' file | awk '$2 > 0 {$2=20;}{print}'

However the file also contains words in the end of the file.
Bla BLA
10 11
11 25
12 30
13 25...

Ive got a file with words and also numbers.
Bla BLA
10 10
11 29
12 89
13 ...

Also just came up with another solotion could maybe come to hand as other users can read this thread as for help.
Its not compiled but it is a solotion...

could this be the answer:
cut -c1-2 filename | cut f2" "-c1-2 filename

Very insecure of the second cut, f2 one.
However if this is the solution i still need them to become variables somehow or...

I am a beginner at shell scripting, actually i am working on my first script right now.
