bash script to select lines

[ionpetrache]

Hello all,

I have a question regarding a bash script:
how can I read a file and put in a array all the lines that are after each blank lines.

ex:

aaa
111

bbb
222
333

ccc
555

put in the array only aaa bbb ccc

welcome to the forum

if the input file is called "w" then this seems to work OK

awk 'BEGIN {ORS=" "};/^$/{getline a; print a}' <w

the regular expression "^$" matches empty lines;
with the Output Record Separator reset to blank
(from newline) we get the next lines concatenated

Thanks a lot!
