Parse config file and store the values in variables
Hi,

I have a config file that has blank, commented lines. I need to escape commented lines, blank lines, parse the remaining lines and store them in variables or array.

the config file contains the following lines.

Code:
# config file
 
# Define Oracle User
ORA_USER=abcde
ORA_PASS=xyzabc
ORACLE_SID=def
 
# CSV file name
#FILENAME=U021999.csv
FILENAME=U025645.csv
#Log file
LOGFILE=Automation_log.xls
OUTPUTFILE=Output.xls

now I want to read the value "abcde" and store it in a variable. like wise I want to read all the values and store in an array.

How can I approach to get values those stored in an array.

thanks,
lakshmi chowdam.

Hi,

try:

Code:
array=(`sed -n "s/^[^#].*=\(.*\)/\1/p" file)

to read the values into the array array.

Print the contents of the array with:
Code:
printf "%s\n" ${array[@]}
