Hello,
I have a bash script in which a variable is set to one or more lines of
text. What I want is to remove any lines up to and including a blank
line (or alternatively to echo all the lines after the last blank line).
There may be zero or more blank lines, and the blank lines need not be
consecutive. If there is no blank line, then all the lines should be
shown. If the last line is blank, then nothing should be shown. So for
example the variable may contain:
============ (the '=' are not part of the variable)
abc def
hijk
xyz
============
So in this case what is wanted is:
============
hijk
xyz
============
to be shown.
I tried something like:
echo "$XX" | sed -e '/./,/^$/d'
but this didn't display anything. (Where XX is the variable.)
echo "${XX[*]/*
}"
