How to parse file and assign parsed contents to variables?

.ksh newbie

Could some please point me to some good help tools on how I can read in a file, and parse out content to assign to variables?

Contents of Example file (misc_data.dat):
warehouse,"/this/that"
home,"/this2/that"
node,"good"

Basically, i want to read in the file and assign "this/that", "this2/that", and "good" to different variables. Is this possible?

Yes, very easily!

Try:

Code:

awk -F\, '{print $2}' your_input_file

When you are happy it is producing what you want, then:

Code:

myvar=$(awk -F\, '{print $2}' your_input_file)

That will, of course, put ALL the output into one variable.
If you know what the 'first bit' of theline is going to be you can do

Code:

mywharehouse=$(grep "^warehouse" your_input_file |awk -F\, '{print $2}')

or something similar
