[SOLVED] get value in inside brackets .Scripting .

[91change]

I am new to script and learning .

I am palnning to get raid status by processing the file /proc/mdstat .


i have an out for cat /proc/mdadm


**************************

Personalities : [raid1]
md1 : active raid1 hdc[2][F] hdd[1]
9920 block [2/1] [_U]

*************************

I am not interested in these details . I need from First line "raid1" . and
giving this as input another script should yield .

md1

If md1 is fed as a parameter to a new script ,it should give hdc , hdd along with their staus codes 2 and failed for hdc , 1 and success for hdd .

II can do only below

Script1 :

cat /proc/mdadm | grep Personalities | awk '{print $2}'

But i dont know how can i remove [ ] from [raid1]


scripts 2:

cat /proc/mdadm | grep raid1 | awk {print $1}'



script3 :

cat /proc/mdadm | grep raid1 |awk '{print $5}

i dont know how to get value 2 and F from hdc[2][F].
and also how many are left (like hdd , hde .hdf etc )


Please help with scripting .

Please don't waste processes by cat-ing a single file to grep

grep Personalities /proc/mdadm | awk '{print $2}' | sed 's/[][]//g'

You have to careful how you arrange the square brackets inside the single-character position range regular expression.

I'll leave you to try to get further with the rest of the script - ask again when you get stuck.

 awk '/Personalities/ {print $3}' /proc/mdadm | tr -d []

Your answer is super .

I found some other methods ,but its not a good solution .
I made use of OR (|) instead of brackets .

grep Personalities /proc/mdadm | awk '{print $2}' | sed 's/\[\|]//g'
