Instead of installing an extra application you could cat your files
through sed.

>From http://www.student.northpark.edu/pemente/sed/sed1line.txt:

TEXT CONVERSION AND SUBSTITUTION:

 # IN UNIX ENVIRONMENT: convert DOS newlines (CR/LF) to Unix format
 sed 's/.$//'               # assumes that all lines end with CR/LF
 sed 's/^M$//'              # in bash/tcsh, press Ctrl-V then Ctrl-M
 sed 's/\x0D$//'            # gsed 3.02.80, but top script is easier

 # IN UNIX ENVIRONMENT: convert Unix newlines (LF) to DOS format
 sed "s/$/`echo -e \\\r`/"            # command line under ksh
 sed 's/$'"/`echo \\\r`/"             # command line under bash
 sed "s/$/`echo \\\r`/"               # command line under zsh
 sed 's/$/\r/'                        # gsed 3.02.80

 # IN DOS ENVIRONMENT: convert Unix newlines (LF) to DOS format
 sed "s/$//"                          # method 1
 sed -n p                             # method 2

 # IN DOS ENVIRONMENT: convert DOS newlines (CR/LF) to Unix format
 # Can only be done with UnxUtils sed, version 4.0.7 or higher.
 # Cannot be done with other DOS versions of sed. Use "tr" instead.
 sed "s/\r//" infile >outfile         # UnxUtils sed v4.0.7 or higher
 tr -d \r <infile >outfile            # GNU tr version 1.22 or higher

You should use xargs in this case.
