# IFS
> 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/html_node/Word-Splitting.html>.
- View the current IFS value:
`echo "$IFS"`
- Change the IFS value:
`IFS="{{:}}"`
- Reset IFS to default:
`IFS=$' \t\n'`
- Temporarily change the IFS value in a subshell:
`(IFS="{{:}}"; echo "{{one:two:three}}")`
