sh != ksh, run it with ksh -x. ksh supports arrays, sh does not, hence the error.

You're not actually using arrays for anything, though, you're just doing string splitting which can happen without using arrays at all.

STR="`cat file`"
echo $STR

But you don't need to load the entire file into a string at all. There's usually no reason to do that.

$ awk -v ORS=" " '{ sub(/[\\]/, ""); $1=$1 } 1; END{ printf("\n") }' inputfile
