Question

Is there any variable in bash that contains the name of the .sh file executed? The line number would be great too.

I want to use it in error messages such as:

echo "ERROR: [$FILE:L$LINE] $somefile not found"

Answer 1

#!/bin/bash

echo $LINENO
echo `basename $0`

$LINENO for the current line number
$0 for the current file. I used basename to ensure you only get the file name and not the path.

UPDATE:

#!/bin/bash

MY_NAME=`basename $0`

function ouch {
   echo "Fail @ [${MY_NAME}:${1}]"
   exit 1
}

ouch $LINENO

You have to pass the line as a parameter if you use the function approach else you will get the line of the function definition.
