How to delete row from text file?

Can I search a 800Meg text file for a specific piece of text, then delete all lines after that text?

• Either delete all lines after the text and save the file or save the text from line 1 to the specific piece of text into a new file. I would like to do this using a program on windows (sed or awk) ?

• Answer:

  That doesn't seem too hard, but not knowing the language you are using I can't really give you any specifics. I would just read through the file line by line (using some getLine() function), then search each line for the text you are looking for. After finding it, I guess it's personal preference how you want to save it. Either way seems equally efficient to me. That's about all I can offer you (I'm not a professional or anything, heh), but I hope that at least points you in the right direction. Consult your programming language's specific documentation to get a better idea (unless you are using the MSDN library - good luck getting any useful info out of that).
