i recently had a similar problem: trying to convert
this:
1<CR>
2<CR>
3<CR>
...
into this: 1, 2, 3...
here is how i did it:
append a comma+space to the end of each line with sed
then remove each CR using tr:
sed -e 's/$/, /g' input_file | tr -d "\n" > output_file
so something like this might do the trick:
awk -F^ {print $6} test.dat | sed -e 's/$/, /g' | tr -d "\n" > output_file
.. you would be left with one column of data that would have to be
re-instered into the DB, or added back to the original file.
the command 'paste' might be helpful for appending the data to the
original...
good luck!
