isArr LinkedIn || LinkedIn=($LinkedIn) |
| 45 |
oIFS=$IFS |
| 46 |
IFS=, # This line and next are what you should |
| 47 |
echo "${LinkedIn[*]}" # be aware of. cf: /msg greybot $@ |
| 48 |
IFS=$oIFS |
| 49 |
|
| 50 |
(We just do: declare -r oIFS=$IFS |
| 51 |
..at the start of our scripts, as it makes life easier in the long-run.) |
