When I do a major change in my entities, I want to find a way to find all my Entities names and create the commande for me.

sort is way slow by default. This tells sort to use a buffer equal to half of the available free memory. It also will use multiple process for the sort equal to the number of cpus on your machine (if greater than 1). For me, it is magnitudes faster.
If you put this in your bash_profile or startup file, it will be set correctly when bash is started.
sort -S1 --parallel=2 <(echo) &>/dev/null && alias sortfast='sort -S$(($(sed '\''/MemF/!d;s/[^0-9]*//g'\'' /proc/meminfo)/2048)) $([ `nproc` -gt 1 ]&&echo -n --parallel=`nproc`)'
Alternative
echo|sort -S10M --parallel=2 &>/dev/null && alias sortfast="command sort -S$(($(sed '/MemT/!d;s/[^0-9]*//g' /proc/meminfo)/1024-200)) --parallel=$(($(command grep -c ^proc /proc/cpuinfo)*2))"
Here is the full function (got trunctated), which is much better and works for multiple queries.
function cmdfu () {
local t=~/cmdfu;
until [[ -z $1 ]]; do
echo -e "\n# $1 {{{1" >> $t;
curl -s "commandlinefu.com/commands/matching/$1/`echo -n $1|base64`/plaintext" | sed '1,2d;s/^#.*/& {{{2/g' | tee -a $t > $t.c;
sed -i "s/^# $1 {/# $1 - `grep -c '^#' $t.c` {/" $t;
shift;
done;
vim -u /dev/null -c "set ft=sh fdm=marker fdl=1 noswf" -M $t;
rm $t $t.c
}

See the total amount of data on an AIX machine.
