Hi all,

Is there other way to Add text at start and ending of every line?

here my script:

cat file.txt |awk '{print "<p align=\"justify\">"$0"</p>"}'

but the problem they put including white spaces, I only need those line have a sentence or text not an skip all have empty string or have a white space

Hello lxdorney,

If I understood correctly you need to skip those lines which are empty, then you can try following. It is good you are showing us what you have tried so far, please try to add your input file and expected output too. Will be helpful for us.

 awk '($0 !~ /^$/){print "<p align=\"justify\"> " $0 " </p>"}'  Input_file

Thanks,
R. Singh

If you want to exclude lines containing <TAB>s and spaces as well, try

awk '!/^[\t ]*$/ {print "<p align=\"justify\"> " $0 " </p>"}'  file

The following takes advantage of awk's autosplit on whitespace.

awk 'NF {print "<p align=\"justify\"> " $0 " </p>"}' file.txt

If you want to keep the blank lines:

awk 'NF {$0 = "<p align=\"justify\"> " $0 " </p>"} {print}' file.txt

You don't need to use cat. Awk can read files on its own.

Here's another way without Awk.

 perl -nle 'print "<p align=\"justify\">$_</p>" unless /^$/' file.txt

you've a DOS formatted file then. first convert it to unix, or amend the script like so:

awk '{sub(/\r$/,"")}NF {print "<p align=\"justify\"> " $0 " </p>"}' file.txt
