Shell Programming and Scripting

HI,

I have to write a unix script and need your help.

in my application where I have to invoke this script a varialble is there where the value comes in a variable . for example variable can be var=ABC
like this there will be any type of value in the vcariable.
there is a unix directory structure where
/home/source/files/
this directory has files like
abc.txt and content of file are
source_directory=/home/abc/source/
target_directory=/home/abc/target/
temp_directory=/home/abc/temp/
arch_directory=/home/abc/archive/

I have to fecth the value of source_directory, target_directory,temp_directory, arch_directory at run time and use this value for further processing.

if Value of variable will be xxx and the file name will be xxx.txt from where values will be picked and values available in file will be

xxx.txt and content of file are
source_directory=/home/xxx/source/
target_directory=/home/xxx/target/
temp_directory=/home/xxx/temp/
arch_directory=/home/xxx/archive/

Code:

 
$ cat temp.cf
source_directory=/home/xxx/source/
target_directory=/home/xxx/target/
temp_directory=/home/xxx/temp/
arch_directory=/home/xxx/archive/
$ cat test.sh
#!/bin/bash
echo -n "Enter the variable : "
read var
echo "Variable value is : $var"
sed "s/xxx/$var/" temp.cf > $var.txt
. $var.txt
echo $source_directory
echo $target_directory
echo $temp_directory
echo $arch_directory
$ ./test.sh 
Enter the variable : ABC
Variable value is : ABC
/home/ABC/source/
/home/ABC/target/
/home/ABC/temp/
/home/ABC/archive/

Hi Kamraj,
I have some scenario where value is different ... like for any file like india.txt values are

Code:

source_directory=/home/india/temp/source/
target_directory=/home/india/temp/target/
temp_directory=/home/india/temp/
arch_directory=/home/xxx/archive/

for some type of files this is changing ... means directory where file is present is one and number of values in the file is same but its values is dfferent..
for source directory, in this case how to pick the values from the file at run time?
