awk ‘max < $1 { max = $1 } END { print max }' Iplogs.txt

The difference in my mind is that the indexes are not necessarily numerically consecutive in the awk cases.... they are more like the keys used in C++ style maps which can take any value as needed to suit the data set. Interesting functionality though, I will be sure to use it at some point I'm sure. Looking at several of these examples here I would refer to these arrays more as MAPS.

Multiarray example: #!/bin/bash Matrix=("one" "two" "three") one=("1.1" "1.2" "1.3") two=("2.1" "2.2" "2.3") three=("3.1" "3.2" "3.3" ) for i in ${Matrix[@]} do one_Item=$(eval echo "\${$i[0]}") two_Item=$(eval echo "\${$i[1]}") three_Item=$(eval echo "\${$i[2]}") done Very gut…
Multiarray example:

#!/bin/bash
Matrix=(“one” “two” “three”)
one=(“1.1″ “1.2″ “1.3″)
two=(“2.1″ “2.2″ “2.3″)
three=(“3.1″ “3.2″ “3.3″ )

for i in ${Matrix[@]}
do
one_Item=$(eval echo “\${$i[0]}”)
two_Item=$(eval echo “\${$i[1]}”)
three_Item=$(eval echo “\${$i[2]}”)
done
