Hi,

I have a function in a bash script that returns a string after some operations using awk.

The following code returns 555


this value I'd like to pass it as a second argument of another script with the following usage


I'm trying to pass the second argument using a pipe but it does not work, no idea why not



Can anyone help me?
many thanks,
rid

Quick fix, but I don't have time to figure out why it wouldn't work


Best regards

thanks, your line worked .

For info, the following one also works



Still don't understand why it does not work with the pipe

a pipe is completely different from a command line option. A standard pipe like so;



the othercommand can grab the piped data by opening STDIN and reading.
Command line options like so;



are supplied to the command in an environment variable.

Also, assuming a modern version of bash, I note that although your way does work the safest approach is like so;



I hope this help with your understanding of pipes

I got it, thanks for the explanation. I was kind of confused but now I see that pipes read from stdin.
