Eh works well enough for display (not file as you mentioned) it's just you |
| 15 |
should know about "${arr[*]}" vs "${arr[@]}" |
| 16 |
Both are designed to help with scriptin; the first with exactly this issue, |
| 17 |
and the latter with handling array parameters correctly, analagous to "$@" |
| 18 |
and "$*". |

Check out http://wooledge.org:8000/BashFAQ/073 for more nice stuff you can |
| 20 |
do with array expansions (as well as scalars.) |

Pfft, you were already using an array: $(IFS=,; echo "${LinkedIn[*]}") |
| 36 |
would've done. Since there was a subshell there, no need to worry about |
| 37 |
saving IFS. Reason I mentioned it is because: unset IFS |
| 38 |
isn't the same, and is generally useless compared to IFS=$oIFS ime. |
| 39 |
(The isArr line just seemed better than '# if this is not an array..') |
