Remove Blank Lines

wwnexc · 05-06-2006, 12:56 AM

Hi,

I am trying to format source code using astyle. So far it all works great, but i have not yet been able to remove empty lines from the code.

Is there any command to remove blank lines, either using astyle or an other program? I was thinking of something like this:

Code:

cat origianl.code | {program_here} | astyle --style=java -T > nice.code

Thanks!

"sed /^$/d originl.code > nice.code" should do it.

Thanks, Antonius_Block! That works like a charm. I was able to even remove lines with spaces by using

sed "/^[:space:]*$/d"

I didn't know about sed until now, thanks for the advise.
