Filter based index array in bash-CodePudding

I need to find a way to filter the variables of an array, following the index of each variable. So far I only have the following example.

DATA[nidforusr1]='jamaica'
DATA[nidforusr2]='brasil'
DATA[nidforusr3]='janaina'
DATA[nidforusr4]='cebola'
DATA[nidforusr5]='batata' 
DATA[nidforbkp1]='ketchup'
DATA[pwforusr1]='sorvete'
DATA[pwforusr2]='google'
DATA[pwforusr3]='pesado'
DATA[pwforusr4]='maluco'
DATA[pwforusr5]='programador'
DATA[pwforbkp1]='macaco'
DATA[ipforusr1]='batata'
DATA[ipforusr2]='senha'
DATA[ipforusr3]='microfone'
DATA[ipforusr4]='passarinho'
DATA[ipforusr5]='abobora'
DATA[ipforbkp1]='caixa'

for ((i=0;i<=${#DATA[@]};i  ))
do
    echo "${DATA[@]:nidforusr1:nidforusr*}"
done

---------------- OR ------------------

for i in ${!DATA[@]}
do
  if [[ "$i" == "nidforusr*" ]]
  then
    echo "${DATA[i]}"
  fi
done

I want to filter the contents of array, but only the contents of array variable that start with index nidforusr

Here's the challenge.

CodePudding user response：

If you fix the position of * and change [i] to [$i], it should work.

declare -A DATA

DATA[nidforusr1]='jamaica'
DATA[nidforusr2]='brasil'
DATA[nidforusr3]='janaina'
DATA[nidforusr4]='cebola'
DATA[nidforusr5]='batata' 
DATA[nidforbkp1]='ketchup'
DATA[pwforusr1]='sorvete'
DATA[pwforusr2]='google'
DATA[pwforusr3]='pesado'
DATA[pwforusr4]='maluco'
DATA[pwforusr5]='programador'
DATA[pwforbkp1]='macaco'
DATA[ipforusr1]='batata'
DATA[ipforusr2]='senha'
DATA[ipforusr3]='microfone'
DATA[ipforusr4]='passarinho'
DATA[ipforusr5]='abobora'
DATA[ipforbkp1]='caixa'

for i in ${!DATA[@]}
do
  if [[ "$i" == "nidforusr"* ]]
  then
    echo "${DATA[$i]}"
  fi
done
