Unix Pipes with out using any turing complete sublanguages. The attempt is to solve programming problems using the pipelines alone. The tools are not restricted to the commonly available tools in unix. Any new tool is allowed as long as it is sharp enough. (i.e does one and only one thing very well).▼

''UnixPipes is really the same language as [[:Category:UNIX Shell|UNIX Shell]].''
▲'''Unix Pipes'''
Using utilities from, [http://packages.debian.org/unstable/utils/moreutils moreutils]
'''unfold'''
Defining unfold as the opposite of xargs, i.e take a list of arguments and send them one at a time.
The definition would be
<lang bash>
|cat unfold
num=$1
while read xxx; do
for i in $xxx; do
echo $i
done |xargs -n $num echo
done
|echo 1 2 3 4 5 6 7 8 |unfold 3
1 2 3
4 5 6
7 8
</lang>
== Deleted solutions ==
We delete a UnixPipes solution when it is too similar to its UNIX Shell equivalent, or when it is incorrect (but the UNIX Shell solution is correct).
# [[Hello world/Standard error]] -- Merged to UNIX Shell.
# [[Sieve of Eratosthenes]] -- Deleted for being incorrect.
# [[Sockets]] -- Merged to UNIX Shell.
# [[String case]] -- Merged to UNIX Shell.
