How to copy a list of files from one directory to another and modify the destination file name on the fly

Question

Could you propose a way to copy a list of files from one directory to another.

During copying the script should capitalize the first letter of the filename and lowercase all other letters.

Answer 1

For your consideration:

for i in *;
do
    fletter=`echo $i| cut -b 1`;                 # FIRST LETTER
    rest=`echo $i | cut -b 2-`;                  # THE REST
    fletter=`echo $fletter | tr "[a-z]" "[A-Z]"`;# CAPITILIZE FIRST LETTER
    rest=`echo $rest | tr "[A-Z]" "[a-z]"`;      # LOWER CASE THE REST
    cp "$i" "/target/directory/$fletter$rest" ;  # COPY TO DESTINATION
done

Here, * will expand to the files in the current directory. If you want this to be restricted to files only, consider the following:

find . -type f -print0 | while IFS= read -r -d '' i; do
    # rest of the script
done
