How about the print files command:

pr -n

All the good answers have been taken.

awk '{printf(&quot;%8d %s\n&quot;, NR,$0)}' file

And also,

sed = file | sed 'N;s/\n/ /'

Has this been done in pure ksh yet?

Cheers,

not yet:

sed = file.txt | sed 'N;s/\n/ /'

With a nod towards tdatgod's solution:

#!/bin/ksh

lineno=0
OIFS=IFS
while IFS=&quot;&&quot; read -r txtline; do
IFS=OIFS
lineno=$((lineno+1))
printf &quot;%8d %s\n&quot; $lineno $txtline
OIFS=IFS
done < d.file

You probably want to use something other than &quot;&&quot; as a field separator. What a hastle!

Regards,

modifying a bit olded idea:

#!/bin/ksh

lineno=0
while txtline=$(line); do
lineno=$((lineno+1))
printf &quot;%8d %s\n&quot; &quot;$lineno&quot; &quot;$txtline&quot;
done < $1

#!/bin/ksh

lineno=0

while txtline=$(line); do print &quot;$((lineno += 1)) $txtline&quot;; done < $1
