i'm willing to provide a small script for you this time, once and explain it as much as i can.

Hopefully we shall see in the future will user lcclaj0 ask simple question again without any tries, but lets assume he is new in scripting and is looking for a simple example.

Code:

INPUTDIR=/directorywithunixfiles
OUTPUTDIR=/directoryforoutput
[ -d $OUTPUTDIR ] || exit 1 # script will exit if $OUTPUTDIR is not a directory.
cd $INPUTDIR || exit 1 # script will exit if it's unable to change directory to $INPUTDIR, additionally it will print the cd command error on stderr
for i in * # for everything in $INPUTDIR 
do
   if [ -f "$i" ]; then # if it's a file use ux2dos utility on it, otherwise silently ignore.
   ux2dos "$i" > "${OUTPUTDIR}"/"$i"
   fi
done
cd - # return to directory the script has been issued from.

Directory /directoryforoutput (destination) will contain converted files with /directorywithunix (source) will contain original files, uneffected by operation (exception being modifed atime -access time, if used on filesystem, by default vxfs - yes.)

This is sample shell script with basic error handling.

Shell commands and constructs used :

1. Variable declaration (directories used INPUTDIR OUTPUTDIR)
2. Conditional operator ( || )
3. Test constructs ([ .. ]) # man test
4. for loop to iterate over the directory contents
5. ux2dos utility to convert format.

Script will not go into subdirectories or process files with dots in names e.g .config

Hope that helps.
Best regards
Peasant.
