<< generate alphabets and append in the input values >>
Hi Team,
Pls help to get the desired output.

I have a input like below

Code:
nodecount=10
host=na7-db1-1-chi

nodecount can be 10 or 8 based on this we need a output (in single line) like below

Code:
na7-db1-1-chi:A na7-db1-2-chi:B na7-db1-3-chi:C na7-db1-4-chi:D na7-db1-5-chi:E na7-db1-6-chi:F na7-db1-7-chi:G na7-db1-8-chi:H na7-db1-9-chi:I na7-db1-10-chi:J

Regards
Kamal

Try something like:
Code:
#!/bin/bash
nodecount=10
host=na7-db1-1-chi
IFS=- read -a H <<< "$host"
C=({A..Z})
for ((i=1; i<=nodecount; i++))
do
  printf "%s " "${H[0]}-${H[1]}-${i}-${H[3]}:${C[i-1]}"
done
echo
