How to initialize a bash array with output piped from another command ?

Question

Is there anyway 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 ?

Answer 1

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))
