So I have this part of a script that creates associative arrays based on output from a yum repolist all command. The script reads line by line and then adds the information into the array. But I have more information that I would like to be added as well. I wrote a script that compares the epoch of when repos are updated from one enviroment to another. dev to test, test to prod.
What I would like, is for the array portion of the script to be able to find the name of the repo, typically held in Repo-id field, and then pull the information in the first part of the script to be input as array items.

Here is what I have so far:

# first sed replaces any blank lines with --

json=$(yum -v repolist all | grep -B2 -A6 "enabled" | sed 's/^$/--/')



# declare a new array to keep things in

declare -A REPO_ARRAY



# read lines and add them to the array if they match

while read line

do

case "${line}" in

    *Repo-name* )

        line=$(echo "${line}" | sed -e 's/^[^:]*://' | sed -e 's,^ *,,')

        REPO_ARRAY[repo_name]="${line}"

    ;;

    *Repo-id* )

        line=$(echo "${line}" | sed -e 's/^[^:]*://' | sed -e 's,^ *,,')

        REPO_ARRAY[repo_id]="${line}"

    ;;

    *Repo-size* )

        line=$(echo "${line}" | sed -e 's/^[^:]*://' | sed -e 's,^ *,,')

        REPO_ARRAY[repo_size]="${line}"

    ;;

    *Repo-updated* )

        line=$(echo "${line}" | sed -e 's/^[^:]*://' | sed -e 's,^ *,,')

        REPO_ARRAY[repo_updated]="${line}"

    ;;

    *Repo-pkgs* )

        line=$(echo "${line}" | sed -e 's/^[^:]*://' | sed -e 's,^ *,,')

        REPO_ARRAY[repo_pkgs]="${line}"

    ;;

    *Repo-expire* )

        line=$(echo "${line}" | sed -e 's/^[^:]*://' | sed -e 's,^ *,,')

        REPO_ARRAY[repo_expire]="${line}"

    ;;

    *Repo-revision* )

        line=$(echo "${line}" | sed -e 's/^[^:]*://' | sed -e 's,^ *,,')

        REPO_ARRAY[repo_revision]="${line}"

    ;;

    *Repo-baseurl* )

        line=$(echo "${line}" | sed -e 's/^[^:]*://' | sed -e 's,^ *,,')

        REPO_ARRAY[repo_url]="${line}"

    ;;

    # if we see -- that means the end of the repo

    -- )

        for i in "${!REPO_ARRAY[@]}"

        if

            grep -q ius <<< "${REPO_ARRAY[$i]}"

        then

            REPO_ARRAY[repo_sync_dev/test]=${iustest_diff}

            REPO_ARRAY[repo_sync_test/prod]=${iusprod_diff}

        fi



        for i in "${!REPO_ARRAY[@]}"

        do

            echo "$i"

            echo "${REPO_ARRAY[$i]}"

        done | jq -n -R 'reduce inputs as $i ({}; . + { ($i): (input|(tonumber? // .)) })'

esac

done <<< "$json"

And I am thinking this would be my value search/input to array but it doesn't seem to be working

if

  grep -q ius "${REPO_ARRAY[$i]}";

then

  REPO_ARRAY[repo_sync_dev/test]=${foo}

  REPO_ARRAY[repo_sync_test/prod]=${bar}

fi

I've tried adding it to the ending echo for loop. To no avail. Not even sure if I am doing this right either.

EDIT:

So it looks like the key's/values are getting added to the output. WHICH IS GOOD! But it's adding to all the enteries. W
hich isn't great.

Don't call out to grep. bash can tell you if an array key exists:

$ declare -A ary=([foo]=bar [baz]=qux)

$ [[ -v ary[foo] ]] && echo y || echo n

y

$ [[ -v ary[nope] ]] && echo y || echo n

n

See help test for the (brief) explanation of -v

I hacked this together, see if it helps:

yum -v repolist enabled | perl -MJSON -00 -lne '

    if ($. == 1) {s/A.+?(^Repo-)/$1/ms}

    s/nh+://sg;

    %info = ();

    for $line (split /n/) {

        ($key, $val) = split /s+:s+/, $line, 2;

        $key =~ s/^Repo-//;

        $info{$key} = $val;

    }

    push @repos, {%info} if $info{name};

  }END{

    print JSON->new->pretty->encode(@repos);

'

which outputs (on a machine near me)
