Pass file name down a pipeline in bash

scasey · 02-26-2018, 09:14 AM

You want to pass the name of the file to the script using pipe?

Code:

echo "file" | myScript.sh

Or am I missing something?

pan64, can you explain more in detail? Tx

what?
If you won't post your script I cannot tell you what should be modified.....

pan64, you wrote "use - as filename"; what do you mean? as for the code, as I said, the grep function is written as _grep -n '#' $inFile | cut -d':' -f 1_ where $inFile takes the value of 'file' when executed as _./myScript.sh file_

"use - as filename" means: "use - as filename". see man grep about it.

Code:

DESCRIPTION
       grep  searches  the  named  input FILEs (or standard input if no files are named, or if a single hyphen-minus (-) is given as file name)
