Changing position of a character in a string
String:
34 /foo/bar_11,,,
I want to insert "34" instead of the second comma. So my string should look like this:
/foo/bar_11,34,
How I can do it?

I think the only way to do this is using capture groups to capture the thing you want to move, and the thing you want to move it past, optionally matching and discarding any unwanted characters such as whitespace, and then replace them in the desired order
Ex.
$ sed -E 's/^([[:alnum:]]+)[[:blank:]]*([^,]*,[^,]*),/21/' <<< '34 /foo/bar_11,,,'
/foo/bar_11,34,
