how to assign output of find into array

Question

In linux shell scripting I am trying to set the output of find into an array as below

#!/bin/bash
arr=($(find . -type -f))

but it give error as -type should contain only one character. can anybody tell me where is the issue.

Thanks

If you are using bash 4, the readarray command can be used along with process substitution.

readarray -t arr < <(find . -type f)

Properly supporting all file names, including those that contain newlines, requires a bit more work, along with a version of find that supports -print0:

while read -d '' -r; do
    arr+=( "$REPLY" )
done < <(find . -type f -print0)
