Hi,

I need to replace a char into a DAT FILE with '0A'  using C under Unix
system.
I have a list of .dat file to do this work and I want to open the file
search for 0D and
replace it with 0D 0A  (HEX) and go for the next file.

Can someone help me?

If it is truly a data file, then inserting as you describe but not as
you said you wanted to do, will likely break the file. If it is a text
file after all, then there already exist tools to do that. unix2dos
comes to mind.

If it is homework, then figuring out how to do it is part of the excercise.

When is your homework due?
