loop checking number of words from array bash-CodePudding

I need help with checking a number next to a word from an array, here is the output from the array:

declare -a my_array=([0]="user.name 16" [1]="user.name2 11" [2]="user.name3 7" [3]="user.name 2"

as you can see, after each username there is a number, what cycle can be used to check exactly (of course, in each element of the array, there can be either 1 or 100) this number (less than 20) and write the username and the original number in the output?

CodePudding user response：

Putting on my mind-reading hat: you can do

for user in "${my_array[@]}"; do
    IFS=" " read -r name number <<< "$user"
    # do something with $name and $number

CodePudding user response：

You can cut the string based on " " and get the number field. For instance:

for I in "${my_array[@]}"; do

  SOME_VAR=$(echo $I | cut -d " " -f 2)
  ...
  <do something with SOME_VAR>
  ...

  # Write username and number to the output
  echo $I
done

This will produce the desired output, by choosing the 2nd field by cutting the string on space ' '.
