How to find the last element in an array in unix?
I think that something like that could make it. It is not very nice, I know, but cannot think in other good ways:
#!/bin/basha=("hello" "bye" "another" "word")i=0num_words=${#a[@]}echo "there are $num_words words"for word in "${a[@]}"do let i=i+1 echo $i $word if [ $i -eq $num_words ]; then echo "last word!" fidoneTest
$ ./testthere are 4 words1 hello2 bye3 another4 wordlast word!
$ set -A arr 1 2 3 4 5$ let LAST_ELEMENT=${#arr[*]}-1$ echo ${arr[$LAST_ELEMENT]}
