Edit and insert character in a text file
Hello All,

Can somebody please help me how to accomplish the following :

I have a text file called data.txt that has the following information :

M|88494-998494
M|98jd#0094
M|88394-994049
M|GFG9980#009944
and so on...


I need to replace the value of M to either "S" or "X" depending on whether there is "-" or "#" in the record. If there is a "-"m replace it with "S".....

Can I just use SED? thnaks!
