It means use any of <, > or , (comma) as a field separator.

Code:
# echo "a<b>c,d" | awk -F"[<>,]" '{print $4, $3, $2, $1}'
d c b a

can someone please explain what this means
Code:
"[<>,]"

Field separators are defined in many ways...
"[<>,]"- Here three filed separators are present <,> and ,.
normally in [] bracket multiple FS are defined which are generally single characters like above.

You can define string/multiple characters as FS also... like below..

">>|<<|AB"- Here two filed separators are >>, << and AB.
