Splitting comma separated values into an array
I'm attempting to create a KSH array out of a string like this: ",,,value1,value2,," I have created the array but I only get two elements, one for value1 and one for value2. I have ended up with something like this but I don't like it: Code:
set -A JUNK
xx=0
for i in $(print ",,,value1,value2,," | nawk '{gsub(/,/," \n",$0);print}')
do
print ".$i."
JUNK[xx]=$i
(( xx += 1 ))
done
for i in "${JUNK[@]}"
do
print ".$i."
done
The results: Code:
. . . . . . .value1 . .value2 . . . . . If i leave out the space character before the newline in this gsub command: Code:
gsub(/,/," \n",$0); ...I get this output: Code:
.value1 . .value2 . I really don't want the spaces at the end of each string and I nead an array of every CSV field (even the empty values). I have tried several approaches including changing IFS and looping through the fields but this doesn't seem to work at all. What am I missing here? Thomas |
