Results of command execution into array
Hi

Can anybody tell me how can I dump the results of execution of a command into array form? For example, I want to execute:

Quote:
fdisk -l | grep 83 | grep Linux
and put each part of the result in an array element:

Quote:
root /home/alireza Revolution 1# fdisk -l | grep 83 | grep Linux
/dev/sda1 1 15000 120487468+ 83 Linux
/dev/sda2 15001 20837 46885702+ 83 Linux

If your system supports process substitution:

Code:
IFS='\
' read -d'^Y' -a array < <(fdisk -l | grep 83 | grep Linux)

'^Y' is just a randomly chosen character that should not occur in the input data (entered using Ctrl-V Ctrl-Y).

If it doesn't support process substitution. Try this:

Code:
fdisk -l | grep 83 | grep Linux > /tmp/tempfile
IFS='\
' read -d'^Y' -a array < /tmp/tempfile
