Get a field value corresponding to another field value

[kichoo]

Hi All,

i am new to scripting

i have a file : file.dat with following data

Code:
STORAGE PERCENTAGE FLAG:
/storage_01 64% 0
/storage_02 17% 1
/storage_03 10% 0
/storage_04 50% 1
I need to get the value of PERCENTAGE in a variable for a value of storage passed as variable

i have tried the following without success like :

percentage='awk -vx="$defaultStorage"  '{FS=OFS=" "}$1==x{print $2}1' file.dat

Please guide me on this..

Thanks in advance

Something like this:

defaultStorage="storage_02"

percentage=$(awk -vx="$defaultStorage" '$1 ~ x{print $2}' file.dat)
