I have a CSV file where data are in the following format
|001|,|abc,def|,123456,789,|aaa|,|bbb|,444,555,666
I want to replace only those "," that appears between numbers with some other character like say SOH or $ or *
other "," appearing in the line should not get replaced i.e. to say I wish to have following output
|001|,|abc,def|,123456*789,|aaa|,|bbb|,444*555*666
Can someone please help me with sed command pattern to get the above desired output

Try this
The first section matches a digit followed by a comma followed by a digit or a -. The next section simply regurgitates the first digit, the replacement character, and then the last digit.
This will catch any pattern like "#,#" or "#,-#", including some that may not be desired (e.g. "abc123,-def" --> "abc123*-def"). Fixing this requires more knowledge of the input stream. (see the comments for details.)
