Reading foreach variable from a text file
Hello,

I have a text file named "foreach.txt" which reads like ---

Code:
foreach cal ( 1 2 3 4 5 )

I am using a simple script which looks like ---
Code:
#!/bin/tcsh
foreach cal (1 2 3 4 5)
echo "$cal"
end

Is it possible to modify the script in such a way that instead of writing
Code:
foreach cal (1 2 3 4 5)------Second line of the script

, we can straight way call/access the text file "foreach.txt" and works as it is.
So, something like
Code:
#!/bin/tcsh
???????cat foreach.txt??????????
echo "$cal"
end

Thanks,

Did you consider the source command/builtin?

Hi RudiC,

Thanks for your r ply. So, do you mean ----
Code:
source foreach.txt

???

Thanks,

Yes, but you'll need to have the entire for construct in that sourced file.

Sorry, I don't know anything about tcsh. In bash, this would work:
Code:
for i in $(cat foreach.txt)
do
echo $i
done

with foreach.txt being 1 2 3 4 5

One could remove the cat
With: $(<foreach.txt)
