[opensuse] Another grep question
Hi all,, I'm not sure if this is a grep or awk question. I have a file with many records of 4 lines each in it. Like this: 1 2 3 4 1 2 3 4 etc, etc I need the file to look like this: 1 tab 2 tab 3 tab 4 1 tab 2 tab 3 tab 4 etc etc.... How can I do this?

I imagine sed is your friend. Replace the newline character with the tab character. Don't ask me the syntax though. Of course, that doesn't take care of the groups for three though...

Perhaps with bash? #!/bin/bash while read line1; do read line2; read line3; read line4; echo -e "$line1\t$line2\t$line3\t$line4" >> outputfile done < testfile -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Jim:
How about a Perl solution?
I'm sure a Perl Guru could do it in one line but it works on a file
created on a Linux box.
If the original data was created on a Windoze box you may need to deal
with other end of line issues. Also, if there are stray spaces laying
around that may cause grief -
Hope it works!
