DOS and UNIX line breaks

Here are my scripts 2unix and 2dos, which convert a given text file to one with guaranteed UNIX line breaks or guaranteed DOS line breaks:


#!/bin/sh
# script 2unix
# AOF 14-6-2-05
# make $1 have LF line breaks
# remove all CR:
sed -i 's/\r//' $1
echo $1 now has only LF \(UNIX\) line breaks.
echo \(To view them use cat -e $1.\)



#!/bin/sh
# script 2dos
#AOF 14-6-2-15
# make $1 have CRLF line breaks
# first remove all CR:
sed -i 's/\r//' $1
# then add CR before each LF:
sed -i 's/$/\r/' $1
echo $1 now has only CRLF \(DOS\) line breaks.
echo To view them use cat -e $1.
