Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

printf "%s " a b c
displays "a b c" Next, there's a shell abbreviation, in bash at least, for all the parameters: $@ Quote it to keep any whitespace:printf "%s " "$@"
Later in the command you use a local variable $a, but you don't alter it, so you may as well use the original $3 (I think). This shortens your command from 235 to 193 bytes.mem(){ { case $1 in st*|[gid]*) printf "%s " "$@";; *) dd if=$3 2>&1|sed '$!d;/^0/d;s/ .*//;s/^/'"$1"' '"$2"' 1 0 /; r '"$3"'' 2>/dev/null;;esac;printf "\r\nquit\r\n";}|nc -n 127.0.0.1 11211; }
Now, if you give us some sample data for the dd/sed part of the command, we'll see if we can simplify that.
