List file names with -v symbol on each line

Question

I have several files in a folder like this,

bob.txt
john.txt
bill.txt

I would like to create a list of this files and adding -v on every line like this,

-v bob.txt
-v john.txt
-v bill.txt

This is the command line to create a simple list, what about -v?

ls *.txt > output

One question, do you just want a file called output with "-v bob.txt", etc on each line? — Richard K Yu, Dec 28 '21 at 16:22
yes just a list of file from a folder with -v in front of each file name — user3224522, Dec 28 '21 at 16:31

Try:

ls *.txt > output
sed -i -e 's/^/-v /' output

Referenced from here

The command on one line

(ls *.txt > output) && (sed -i -e 's/^/-v /' output)

how to put these two command lines in one? ls *.txt | sed -i -e 's/^/-v /' > output ? – user3224522 Dec 29 '21 at 09:31
One second let me see – Richard K Yu Dec 29 '21 at 09:47
Does (ls *.txt > output) && ( sed -i -e 's/^/-v /' output) work for you? – Richard K Yu Dec 29 '21 at 09:58
