super thank you.

awk -F. 'NR==1 {pre=$1"."$2; a=$3; d=$4} NR==2 {b=$3; c=$4} END {for(i=a;i<=b;i++) for(j=d;j<=c;j++) print pre"."i"."j}' input_file

works great if the input file is like

192.168.0.1...

I am trying to find a script that will generate all the ip addresses in particular range.

Example: start: 41.0.0.0 end ip 41.1.1.2

32.32.35.3 to 32.32.36.0


Please help.

Thanks

thanks...the python example works but the bash one.

Just wonder if there is a command that prints out letters from a to z in alphabetical order.

Thanks

here is my code:

sql=`mysql Live -e "select * from name where name='test' \G"`

echo $sql


test: line 3: syntax error near unexpected token `sql=`mysql Live -e "select * from name where...

sorry for the confusing...

awk 'FNR==NR{a[$0]++; next} !a[$0]' current.uid user.uid

is what I wanted..

Thanks for your help.

it prints out the output of user.uid..which is not what I wanted.

Thanks btw

Hi there,

I have 2 files:

current.uid

5516
5517
5518
5519
5520
5521
5522
5523
5524
5525

user.uid

5506

there is nothing wrong with it. It's just that I wanted to try to use loop to get this done.

Here is what I tried:

v=$(echo "1 2 3 4")
t=$(echo "a b c d")

test=$(for x in $v
do
for y...

can it be done without writing files to the system?

Thanks

Thanks cfajohnson. Your suggestions work fine but I am still having issue:

basically where is what I have

v=$(echo "1 2 3 4")
t=$(echo "a b c d")

I'd like to print out

1/a
2/b
3/c...

Hope someone can help me.

I have 2 outputs

1 2 3 4 5

a b c d e

basically, I'd like to loop thru these outputs and print out the results below

1/a
2/b
3/c
4/d
5/e

Thanks,

ifconfig -a eth0 | grep "inet addr"| awk '{print $2}' | sed 's/addr://'

that would work fine for regular linux server.

The hostname is actually the last octet of the ip. I ended up creating a separate hostname file and was able to get the final result with Sergiu-IT's script.

Thanks for the script. It works great...

I have 2 files one of them has all the all mac addresses and the other one has all the ip addresses. Basically, I want to loop thru those 2 files and generate a configuration like below:

host...
