Ok, to get you started in Bash.
I don't know enough Bash to do arrays or lists, so lets just concentrate
on argument lists to a function or a script.
cat listtocsv.sh
#!/bin/bash
delim=""
for tok in $*
do
str="$str${delim}$tok"
delim=", "
done
echo $str
./listtocsh.sh 1 2 3 4
1, 2, 3, 4
The trick is to eliminate the trailing ", " from the last element of the
list:
1, 2, 3, 4,
Since Bash doesn't have true functions (that return arbitrary values,)
the recursive version of this isn't shorter. Can anyone see any
improvements?
Up next: The Ruby one.
