I have a long text that i want to shorten to another text file mytext.txt TO mytext2.txt (short version)
i would like to remove everything before the symbol >>__________ below in mytext2

so in brief:
mytext.txt is complete, mytext2.txt shows everything AFTER the '>>__________' symbol that appears in mytext.txt

any suggestions on the shortest possible route to do this would be appreciated.
thanks
k
