Hi Julio,
to examine whether it is indeed stuck in the copy, you can open
another term and look at the $file.orig version with tail, and then
at the resulting $file with tail.
I suspect that you might have missed something in the echo which
follows the sed:
echo '
#undef STANDARD_STARTFILE_PREFIX_1
#undef STANDARD_STARTFILE_PREFIX_2
#define STANDARD_STARTFILE_PREFIX_1 "/tools/lib/"
#define STANDARD_STARTFILE_PREFIX_2 ""' >> $file
touch $file.orig
Note that the first line is a single quote follwed by the newline
then 4 lines get echo'd and the fourth line has the terminating
single quote follwed by the '>>' to append it.
Therefore the copy should have four additional lines at the end of
it if the echo command was pasted correctly.
I'm guessing one of the quotes or double quotes, or even the 'done'
maybe got missed.
But with luck that process will soon be old history with LFS-10.0.
