How to run a file in a csh script?
Hi,
I have a csh script. I want to set some variables and execute some command from a file in that script.

abc.csh
Code:
echo "primary script"

b
Code:
setenv XXX ddd
set XX 
make abc

I want to execute the commands of "b" file from abc.csh. How can i do that.

try this in the "abc.csh"
Code:
#!/bin/csh
echo "primary script"
/bin/csh -c /relative/PATH/b

What is wrong with the way i am doing it?
Code:
foreach line ( "`cat b`" )
 echo $line
exec  $line
end

Whats the difference if i source the "b" file in "abc.csh" file rather then executing it.

try with eval instead of exec
Code:
exec [-cl] [-a name] [command [arguments]]
              If command is specified, it replaces the shell.  No new process is created. 

eval [arg ...]
The args are read and concatenated together into a single command.  This command is then read  and  executed  by the  shell,
