Length: ${#arrayName[*]} or ${#arrayName[@]}
Indexes: ${!arrayName[*]} or ${#arrayName[@]}
Example:
#!/bin/bash
group1=(rio amos)
group2[0]=bill
group2[1]=frank
group2[2]=bruce
echo group1 has ${#group1[*]} person[s]
echo they are ${group1[*]}
echo group2 has ${#group2[@]} person[s]
echo they are ${group2[@]}Associative Array：
Define: declare -A arrayName
Assign1: arrayName=([index1]=value1 [index2]=value2 ...)
Assign2: arrayName[index]=value
Length: ${#arrayName[*]} or ${#arrayName[@]}
Indexes: ${!arrayName[*]} or ${#arrayName[@]}
Example:
#!/bin/bash
declare -A team1
declare -A team2
team1=([rio]=1981 [amos]=1990)
team2[frank]=1983
team2[bill]=1984
team2[bruce]=1990
echo team1 has ${#team1[*]} person[s]
echo they are ${!team1[*]}
