### TODO #### for now only max 9 example possible.  
# Warning! If add plus myPrompt example, then change maxnumber!
maxnumber="6"

# currently used
prompt="$(awk -F '"' '/^prompt/ {print $2}' ~/.bashrc)"
number="$(echo "${prompt}" | tail -c2)"

elif [ "${number}" = "" ]; then

 Ha a .bashrc fájl tartalmaz prompt="myPrompt" sort, akkor a számnak megfelelő PS1 aktiválódik.
