I am always typing things like this:

cat some_list_of_elements.txt | awk '{print "047"$1"047"}' | paste -d, -s

It takes a list of items from a file, wraps each in quotes, and merges them together in a comma-separated list.

Rather than typing out all that stuff, I'd like to do something like this:

cat some_list_of_elements.txt | csl

How can csl be implemented in bash? Is there a way to do it as an alias?
