dos2unix
Single Command Wrapper Script
perl -pi -e 's/\\r//' [file]
#!/bin/sh
# Copy to /usr/local/bin/dos2unix

if [ "$1" = "" ]; then
    echo Usage: `basename $0` [filename]
    exit
fi

# Convert to Unix format.
perl -pi -e 's/\\r//' $1
unix2dos
Single Command Wrapper Script
perl -pi -e 's/\\r//; s/\\n/\\r\\n/' [file]
#!/bin/sh
# Copy to /usr/local/bin/unix2dos

if [ "$1" = "" ]; then
    echo Usage: `basename $0` [filename]
    exit
fi

# Force to Unix format first...
perl -pi -e 's/\\r//' $1

# ...and then convert to DOS.
perl -pi -e 's/\\n/\\r\\n/' $1
