Data File Example:
Code:
$ cat data
Knight Eon >,,,,
Hello World >,,
Hello Earth >
How is everyone >,,,,,, Around >,, Yo >,

The relevant SED Script:
Code:
sed -e 's/>,*/>/g' data

Output:
Code:
$ sed -e 's/>,*/>/g' data
Knight Eon >
Hello World >
Hello Earth >
How is everyone > Around > Yo >

Combining your second query:

Code:
$ sed -e 's/>,*/>/g;$s/.*/Hello/g' data
Knight Eon >
Hello World >
Hello Earth >
Hello
