Top Forums Shell Programming and Scripting Bash script to take cPanel backup in batches Post 303018243 by MadeInGermany on Friday 1st of June 2018 07:56:12 AM
Old 06-01-2018
Simplified: the outer loop increments by 5
Code:
#!/bin/bash
# bash or ksh93
nump=5 # number of accounts per processing, increase or decrease

# plain text file with account1 to account39, each in new line is created named 'accs.txt'
# for test input, fill array 'accounts' with results
na=0
while read accs 
do
  accounts[na]=$accs
  na=$((na+1))
done < accs.txt

for (( begin=0; begin<na; begin+=nump ))
do
  # If utilities used support multiple accounts input, a for loop is not neccesary.
  # this takes care of reminder as well
  for account in "${accounts[@]:begin:nump}"
  do
    echo "work on $account"
  done
  echo "group action for ${accounts[@]:begin:nump}"
  sleep 1 # we sleep here 1 second after 5 accounts have been processed, you might not.
done

Now a "classic" variant without an array
Code:
#!/bin/sh
# any Posix sh
nump=5 # number of accounts per processing, increase or decrease

# the final group action is after the loop, so we put it in a function
group_action(){
  echo "group action on
$accounts"
  sleep 1
}

# plain text file with account1 to account39, each in new line is created named 'accs.txt'
i=0 na=0 accounts=""
while read account 
do
  accounts=$accounts${accounts:+"
"}$account
  echo "work on $account"
  if [ $((i+=1)) -eq $nump ]
  then
    group_action
    accounts=""
    i=0
  fi
  na=$((na+1))
done < accs.txt
[ $i -ne 0 ] && group_action
