Let's assume that the field separator is :
var='1:2:3:4:
newline'
arr=()
while IFS= read -d : -r field || [ -n "$field" ]; do
arr+=("$field")
done <<< "$var"
echo "${arr[4]}"
Output:
newline

The following script shows more advanced split file technique, where FOR function loops through a list of files in a directory, and each file content is piped to FINDSTR that looks for a string containing substring var preceded by undefined number of spaces and superseded by any extra text.

Basic Syntax
Julia's array comprehensions use the following syntax:
[expression for element = iterable]
Note that as with for loops, all of =, in, and ∈ are accepted for the comprehension.
This is roughly equivalent to creating an empty array and using a for loop to push! items to it.

Julia uses the standard mathematical meanings of arithmetic operations when applied to matrices. Sometimes, elementwise operations are desired instead. These are marked with a full stop (.) preceding the operator to be done elementwise. (Note that elementwise operations are often not as efficient as...
We can just do simple replacement of separators from space to new line, as following example.
echo $sentence | tr " " "\n"
It'll split the value of the variable sentence and show it line by line respectively.
