Hello everybody,

I need to concat the results of two distinct lists of file and make one
unique list.
Something like that:

list1='ls .txt'
list2='ls .xml'

I would like to have list = list1 + list2 (and then use the elements of
list) but i cannot find the right command to do that.
Note that the list1 and list 2 are retrieved in different part of a
code (otherwise i would use a unique command).

Thanks!

Is
echo $list1 $list2 | sort | unique
OK?

a) quote your variables
b) sort has a -u option

Do you mean:

list1=`ls *.txt`
list2=`ls *.xml`

list3="$list1
$list2"
