You're debugging a script and notice that an operation splits a string incorrectly. You suspect it might be related to the field separator. Which built-in variable should you check?
- IFS (Internal Field Separator)
- FS (Field Separator)
- OFS (Output Field Separator)
- RS (Record Separator)
You should check the IFS (Internal Field Separator) built-in variable. It determines how fields are separated when splitting strings. Changing the IFS value can affect string splitting and tokenization in scripts, so it's essential to inspect and modify it when debugging string manipulation issues.
