Urgent! UNIX shell scripting question! - microchip13 - 02-19-2006 if I'm trying to do something like 'sed - $variable p' to output a specific line, how would I get it so there aren't any spaces? would I have to use tr? using the above I get sed - X p when I need sed -Xp Thanks in advance! Re: Urgent! UNIX shell scripting question! - shadow - 02-19-2006 Is this what you are looking for: sed -${variable}p - Shadow Re: Urgent!
