IFS (Internal Field Separator) is a special environment variable that defines the delimiter used for word splitting in Unix shells. The default value of IFS is a space, tab, and newline. The three characters serve as delimiters. More information: https://www.gnu.org/software/bash/manual/bash.html#Word-Splitting.
