Perl command to change file EOL and saving the file with the same name

Question

I am using this perl command on my debian to change my file EOL:

perl -p -e 's/\n/\r\n/' < ~/scripts/bite/EOL/*.csv > ~/scripts/bite/sent/samefilename.csv

Every day there will be a new file in the "EOL" directory with a different name and it always has only 1 file in the directory, so I am using "*" to take whatever file is in it. But i need to save the new file with the same name as the file I chose to change without manually entering the file name to the command. Eventually this goes into my cronjob, so everything would be automatic.

EDIT: Fixed my problem by using "unix2dos"

`perl -pie` comes to mind, but then you'd have to copy the file to the target dir first and read it from there. Or copy it somewhere else, process it, then copy it to the target. — simbabque, Nov 20 '20 at 09:31
Why not to use command `unix2dos` or editor `vim` ( :set ff=dos)? — Polar Bear, Nov 20 '20 at 11:09
@PolarBear I am open to all suggestions as well yes. Il check them out. — BrandoN, Nov 20 '20 at 11:12
@PolarBear I got my problem solved with "unix2dos", thank you. Could you make an answer so i could accept? — BrandoN, Nov 20 '20 at 11:34
Per your request I've added the answer (someone might find it useful). — Polar Bear, Nov 22 '20 at 06:43

I would use the unix2dos utility, but you can also use

perl -pe's/\n/\r\n/' -i file.csv

See Specifying file to process to Perl one-liner.

Your program and this one only works on unix systems.

Linux has command unix2dos and dos2unix for converting eol from MS Windows/DOS to UNIX format. Perhaps it is easiest solution for described problem.
