Question

I need to depend on few separate executions in a script and don\'t want to bundle them all in an ugly \'if\' statement. I would like to take the exit code \'$?\' of each executi

As mouviciel mentioned collecting sum of return codes looks rather senseless. Probably, you can use array for accumulating non-zero result codes and check against its length. Example of this approach is below:

#!/bin/sh

declare RESULT
declare index=0
declare ALLOWED_ERROR=1

function write_result {
    if [ $1 -gt 0 ]; then
        RESULT[index++]=$1
    fi
}

true
write_result $?

false
write_result $?

false
write_result $?

echo ${#RESULT[*]}
if [ ${#RESULT[*]} -gt $ALLOWEDERROR ] 
   then echo "Too many errors"
fi
