Most Unix installations include the 'tr' command ('tr' is short for 'translate'). You could use that to convert your input file with DOS text to output the Unix text format:
tr -d '\r' < dos.txt > unix.txt
On Debian-derived (Ubuntu, etc.) systems, you want the tofrodos package, which provides the commands todos and fromdos. (fromdos is the one you are looking for.)
On Red Hat Linux-derived systems (RHEL, CentOS, Fedora, etc.), you want the dos2unix package, which provides the commands dos2unix and mac2unix. To convert in the other direction, you'll want the unix2dos package, which provides the unix2dos command.
Do you mean: You want to convert Windows text files into Linux text files? If yes: There's a utility dos2unix that will do the job for you.
