last element of an array

The syntax I'm currently using to access the last element of an array looks a little evil: >arr=( one two three ) >echo ${arr[$(([EMAIL PROTECTED]))]} three If there is not currently a friendlier syntax for this, might I suggest: ${arr[-1]} -- Poor Yorick ___

mkfifo and tee within a function

Hi, Within a function, I'd like to print some input to the terminal and at the same time store it in a fifo fostore some input in a fifo, but am getting mixed results. In this example, I thought "hello" would be output twice: $>cmd_print () { mkfifo zout ; (tee zout &); cat zout ; rm zout; }

I'd like to use a bash script in a pipe to process null-delimited output: | myscript > results Since the "read" command seems to currently be unable to use ascii null as a delimiter, I'm using xargs to parse the file and feed to a subshell: *** contents of myscript*** cat <&0 | xargs -0 -n2 b

read command and ascii null as delimiter

Feature request: an option, maybe "-0" to use ascii null as the delimiter for the "read" command. It would make the following two commands produce the same output: [EMAIL PROTECTED]:~/tmp5$ printf 'hello\000there' | xargs -n1 -0 echo hello there [EMAIL PROTECTED]:~/tmp5$ printf 'hello\000there
