Create and paste two file into one
Hello
i want to create this list:
Code:
2a05:b80:0:235::9f/1159
2a05:b80:0:235::a0/1160
2a05:b80:0:235::a1/1161
2a05:b80:0:235::a2/1162
2a05:b80:0:235::a3/1163

so write this shell as well:
Code:
#Global VAR
STR=159
END=200

#INI NET IPV6 PART
SUM1=`expr $END - $STR`
for ((i=STR;i<=END;++i)); do
echo -e "2a05:b80:0:235"$x >> host-part.txt
done

#INI HOST IPV6 PART
STR2=159
END2=200
SUM2=`expr $END2 - $STR2`
for ((i=STR2;i<=END2;++i)); do
x=$( printf "%x" $i ) ; echo $x
echo -e "::"$x >> netpart.txt
done

if [ $SUM1 == $SUM2 ]; then
        paste -d '' host-part.txt netpart.txt > IP-LIST.txt

        ## creating file for port ranges ##
        STR3=1159
        END3=1200
        for ((i=STR3;i<=END3;++i)); do
        echo -e "/"$i >> port.txt
        done
        SUM3=`expr $END3 - $STR3`
                if [ $SUM1 == $SUM3 ]; then
                        paste -d '' IP-LIST.txt port.txt > final-config
                else
                        echo "Error on sum ip port"
                fi

it do what i want but the question is how can i ask user to enter number instead of having three SRT and END variable:
STR STR2 STR3 END END2 END3

and how can i make it More functional and principled?

Some comments:
- in your host-part.txt creation loop, you're using the undefined $x variable.
- the final fi is missing for the first if construct, and there is no error handling (else branch) either.


EDIT: How about
Code:
read -p "enter STR1 END1 STR2 END2: " STR1 END1 STR2 END2 
if (( END2 - STR2 != END1 - STR1 ));  then echo different ranges.; fi
DLT=$((STR2 - STR1))
for ((i=STR1;i<=END1;++i))
  do    printf "2a05:b80:0:235::%X/%d\n" $i $((i+DLT))
  done

enter STR1 END1 STR2 END2: 159 200 1159 2000
2a05:b80:0:235::9F/1159
2a05:b80:0:235::A0/1160
2a05:b80:0:235::A1/1161
2a05:b80:0:235::A2/1162
2a05:b80:0:235::A3/1163

tx
but output is just a line:
Code:
[root@localhost ~]# sh mm
enter STR1 END1 STR2 END2:159 200 1159 2000
2a05:b80:0:235::0/0

My fault, sorry; I used a line from your scipt above instead of mine.
Use
Code:
for ((i=STR1;i<=END1;++i))

in the for loop.

Or, if your shell (which, btw, you fail to mention) allows for "process substitution" ( so - don't use sh to run the script!):

Code:
printf "2a05:b80:0:235::%X/%d\n" $(paste <(seq $STR1 $END1) <(seq $STR2 $END2))
2a05:b80:0:235::9F/1159
2a05:b80:0:235::A0/1160
2a05:b80:0:235::A1/1161
2a05:b80:0:235::A2/1162
2a05:b80:0:235::A3/1163

still oneline is output of
Code:
read -p "enter STR1 END1 STR2 END2:"
if (( END2 - STR2 != END1 - STR1 ));  then echo different ranges.; fi
DLT=$((STR2 - STR1))
#for ((i=STR1;i<=END1;++i))
for ((i=STR1;i<=END1;++i))
  do
printf "2a05:b80:0:235::%X/%d\n" $i $((i+DLT))
$END2))
  done

let me say again what this script do:
this script try to get range of ip and range of port then point each port to ip and save them into one file,
2a05:b80:0:235::XX
is the main ip and this script try to create list of ipv6

my code try to create list of ips then list of ports then paste them together into one file,

oh,
Code:
printf "2a05:b80:0:235::%X/%d\n" $i $((i+DLT))

%X >>>> %x

$END2))
  done

First line is missing list of variables to read, replace line 1 with:

Code:
read -p "enter STR1 END1 STR2 END2:" STR1 END1 STR2 END2

Remove line highlighted in red


Edit: Below is a example using bash with user friendly prompting (entering IPs in Hex with validation):

Code:
#!/bin/bash
hex_to_dec() {
  [[ $2 =~ ^([[:xdigit:]])+$ ]] &&
  printf -v $1 "%d" $((16#$2)) &&
  (($1 <= 16#FFFF ))
}
while true; do
   read -p "Start IP in hex: " sx
   hex_to_dec STR1 $sx && break
   echo "Invalid Start IP please reenter"
done
while true; do
   read -p "End IP in hex: " ex
   hex_to_dec END1 $ex && ((END1 >= STR1)) && break
   echo "Invalid End IP please reenter"
done
read -p "Start port: " STR2

DLT=$((STR2 - STR1))
for ((i=STR1;i<=END1;++i))
do
    printf "2a05:b80:0:235::%x/%d\n" $i $((i+DLT))
done
