Sed Style

from the sed 1liners...

http://www.dbnet.ece.ntua.gr/~george/sed/1liners.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$//' # sed v1.5 only

tr -d '\015' < "$x" > "tmp.$x"
Will script create this tmp file? Will I need to create this tmp file by myself?

This script makes tmp file and overwrite original file. You don't need to do anything.

Thanks for sharing this!!!!

I was having some issues with the tmp file not being found. I ended up contacting the string and then run the code. Here is what I ended up doing in the end.

for x
do
    echo "Converting $x"
    temp_file+="tmp."$x
    tr -d '\015' < "$x" > temp_file
    mv temp_file "$x"
done
