I have this scriplet that pulls data from a ldap. it lists the attributes with the cn and the value. but it goes through all the attributes of a cn and then moves to the next.
for node in "${HOSTS[@]}"; do
LDAP_URI="ldaps://${node}:${LDAP_PORT}"
while IFS=: read -r key val; do
[[ $key = cn ]] && { cn=${val# }; continue; }
if [[ $val =~ ^\ -?[0-9]+(\.[0-9]+)?$ ]]; then
attr=$(sed 's/-/_/g' <<< "$key")l"
printf '%s, cn="%s %s\n"' "$attr" "$cn" "$val"
fi
done < <( ${LDAPSEARCH} -LLL -H "${LDAP_URI}" -x -D "${BINDDN}" -w "${LDAP_PASSWD}" -b "cn=monitor")
done;
the code above produces output like this:
"connections, cn="1636 -632
"bytessent, cn="1636 492842558
"connections, cn="1389 698
"bytessent, cn="1389 389256181
but I do not want to group by cn but group by attribute like this:
"bytessent, cn="1389 389261940
"bytessent, cn="1636 711130488
"connections, cn="1389 700
"connections, cn="1636 -632
what would be the best way to achieve this?
One idea would be to pipe the entire output to sort.
I don't have all the bits-n-pieces to get OP's working so I'll simulate with an echo:
echo '"connections, cn="1636 -632
"bytessent, cn="1636 492842558
"connections, cn="1389 698
"bytessent, cn="1389 389256181' | sort
This generates:
"bytessent, cn="1389 389256181
"bytessent, cn="1636 492842558
"connections, cn="1389 698
"connections, cn="1636 -632
Adding to OP's code (see last line):
for node in "${HOSTS[@]}"; do
... snip ...
done | sort # send all output to sort
I'm guessing OP really wants to end each line with a " so that it looks like:
"bytessent, cn="1389 389256181"
"bytessent, cn="1636 492842558"
"connections, cn="1389 698"
"connections, cn="1636 -632"
To accomplish this just need to tweak the printf format to switch the last " and the \n:
printf '%s, cn="%s %s\n"' "$attr" "$cn" "$val" # before
printf '%s, cn="%s %s"\n' "$attr" "$cn" "$val" # after
