Hello everyone, I have a file (tapes to be ejected from library) and need to insert a blank line and the statement eject 0,1,0 after every 14 lines. I'm going crazy trying to find a sed command but its not working. using ksh Thank you guys Linda

Linda: You'll get more timely answers for unix scripting over in the unix forum, but ... Here's a sed solution: sed 'x s/$/#/ /#\{14\}/{ a\ eject 0,1,0 s/.*// } x' data.file I borrowed this so don't even ask me to explain it. Go here for that: http://main.rtfiber.com.tw/~changyj/sed/html/p.20010222a.html If it were me, I'd set up a ksh while loop and read the file a line at a time.
