A space among several lines

[Manuales]

Hi ...
how can i give an space among different lines into the script?

if [[ $v_porc != $v_porc_temp ]]; then
mm="si"
echo "FILE SYSTEM SIZE HAS CHANGED -> Before $v_porc NOW $v_porc_temp >> ${B}_APPL_filesystem_DIFF
fi

I know that i have to use something like \p, what is that i have to use?

For example for this one:
FILE SYSTEM SIZE HAS CHANGED -> Before 71 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 54 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 49 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 28 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 81 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 47 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 47 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 99 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 99 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 99 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 99 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 97 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 97 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 99 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 99 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 99 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 96 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 95 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 90 NOW 100 FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 10

I need so:
FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 10
FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 10
FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 10
FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 10
FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 10
FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 10
FILE SYSTEM SIZE HAS CHANGED -> Before 98 NOW 10

All that you need is the terminating double-quotes on the echo command i.e.

echo "FILE SYSTEM SIZE HAS CHANGED -> Before $v_porc NOW $v_porc_temp" >> ${B}_APPL_filesystem_DIFF

I did that .. but it did not work!!! :(

echo "FILE SYSTEM SIZE HAS CHANGED -> Before $v_porc NOW $v_porc_temp - FS: $v" >> ${B}_APPL_filesystem_DIFF

Try the echo command below; notice the newline character \n before the output re-direction

echo "FILE SYSTEM SIZE HAS CHANGED -> Before $v_porc NOW $v_porc_temp\n" >> ${B}_APPL_filesystem_DIFF

I would have thought that this would create double spacing and the \n would not ordinarily be needed. (In fact you need a \c to remove it.)
