Remove First Char from Line in File Only if it's a comma
I have a file, I need to remove the first character of each line, but only if it's a comma. I don't want to delete any other commas in each line.

Trying cat or sed but I really don't know them very well, would love some help.

This removes the first comma, but it removes the first comma no matter where it is in each line.
Code:
cat in.txt | sed 's/,//' > out.txt

Thanks!
Cynthia
