Shell Programming and Scripting

Hi,
I have a shell script 'sample.sh' which has some functions as below.

Code:

#fun1
fun1()
{
date
}
 
#fun2()
{
echo hi
}

I want to run these functions as background processes and also redirect the output to a file. My function calling statements are in a different file 'sample.cfg' as below.

Code:

fun1 > fun1.log &
fun2 > fun2.log &

I am running a while loop in the main script which will read the file having the function calling statements and execute them as below.

Code:

while read fn
do
   `$fn`
done<sample.cfg

But the above code doesn't work. I found that it first executes the commands inside the function and then tries to execute the output of the commands as well and result in error as below.

Code:

[ukuxcent03:mqbrk22s:/home/mqbrk22s:] sample.sh
sample.sh[20]: Mon:  not found.
sample.sh[20]: hi:  not found.

I also tried the below code.

Code:

while read fn
do
   result=`$fn`
   echo $result
done<sample.cfg

This also doesn't work. It considers redirectional operator '>' and '&' as arguments to the function.

Can anybody help on this? I am attaching the sample.sh and sample.cfg.

code tags please

Hi Rama,
Want to know what are the contents of sample.cfg.
In sample.sh it seems that you have commented fun2().Please remove#.

Try this:

Code:

while read line
do
  result=$line
  echo $result
done < sample.cfg

Sorry...Missed the attachment file

Hi aashish, content of sample.cfg is as below.
fun1 > fun1.log &
fun2 > fun2.log &

I don't want to print the output of the function to the screen. Instead i want to rerdirect it to a file. If you see the function call statements above that is what i am dioing. But this doesn't work.

Is there any way to interpret the symbols '>', '&' in the function call statement which is read from the file sample.cfg as operator instead of arguments to the function?

Idea: Instead of these 4 lines, make sample.cfg executable and run it with a "dot space" command so that the lines execute within the same shell as the functions:

Code:

. ./sample.cfg
