How do you preserve the max length of a line after replacing a specific value?
I'm new with scripting and I can't seem to figure out what I should do to get the output that I want.
My file content would be below.
I'm trying to replace the field of ID3 which has a fixed length of 10 characters, for each entry I have placed on a .txt file and placing the value on variable called "NEW".
Here is my sed command.
Is there anyway to maintain the 10 characters on the field for each entry it reads on my .txt file?

Hi,
I'm attempting to rename some files that have spaces in them. Without linking sed commands together is it possible to replace the first three "." to " ".

echo "File.name.is.long.ext" | sed 's/\./ /g;s/... (5 Replies)
hai guys,

if suppose max length is 2,
then compare the all records if <2 then add zero's prefix of the record.
