Is there any way to pipe the output of a command which lists a bunch of numbers (each number in a separate line) and initialize a bash array with those numbers?

Details:
This lists 3 changelist numbers which have been submitted in the following date range. The output is then piped to cut to filter it further to get just the changelist numbers. 

p4 changes -m 3 -u edk -s submitted @2009/05/01,@now | cut -d ' ' -f 2

E.g. : 

422311
543210
444000

How is it possible to store this list in a bash array?

    You can execute the command under ticks and set the Array like,

    ARRAY=(`command`)

    Alternatively, you can save the output of the command to a file and cat it similarly,

    command > file.txt
ARRAY=(`cat file.txt`)

    Or, simply one of the following forms suggested in the comments below,

    ARRAY=(`< file.txt`)
ARRAY=($(<file.txt))
