how to add a blank line inside the file
Hi,
I need to add a blank line before/above the word "do" in my file.
This file contains some other words with "do" segment, such as "done" or "rdonly" and the only instance of "do" as a word.
The blank line needs to be added above the actual "do" word.
Is there a command which I can use to do that? I am in ksh88.
Thanks a lot for any help or advice. -A

One way:

Code:
awk '/^do$/{print ""}1' file > new_file

Franklin, I keep getting this error:
op - sundev1 $ awk '/^do$/{print ""}1' px2158.files.2b.deleted > px2158.files.2b.deleted.new
awk: syntax error near line 1
awk: bailing out near line 1
Not sure why... Any idea?

As yahyaaa mentioned, use nawk, gawk or /usr/xpg4/bin/awk on Solaris.
