echo ${#str_list[@]}
for i in ${str_list[@]}
do
  echo "$i"
done

# Script to split a string based on the delimiter
my_string="Ubuntu;Linux Mint;Debian;Arch;Fedora"
IFS=';' read -ra my_array <<< "$my_string"

#Print the split string
for i in "${my_array[@]}"
do
    echo $i
done

# Script to split a string based on the delimiter
my_string="Ubuntu;Linux Mint;Debian;Arch;Fedora"  
my_array=($(echo $my_string | tr ";" "\n"))

#Print the split string

do
    echo $i
