How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
lang-bash
bashone removes the last field if it's empty (bash'sread -acan't be used for reading separated values) while the perl one removes all empty trailing fields.$IFScontains its default value, the xpg_echo option is not enabled and/or input lines are not things like-neen..., both assume that words in the name field are whitespace separated (only space and tab in the bash one) and will mangle spacing there. (not worse than the OP's attempt though in those regards)
