sed

I have a sequential file that has variable length records in it. I would like to add spaces to the end of each record to make the total record length = 1123 by adding spaces to the end of each record. Can this be done with sed?

Thanks

i'm not to sure about using sed, but it should be quite easy with any utility that has a printf statement, awk, shell, perl, etc

awk:

cat file | awk '{
printf("%-1123s\n",$0);
}'

or in the shell

while read line
do
printf "%-1123s\n" $line
done

Hi,

I liked Curt's idea.

awk '
{ if (length($0) > 1123) print $0 ;
else printf("%-1123s\n",$0) }' data2 > out

To make sure it doesn't truncate the records of length more than 1123.
