As I understand the variable is interpreted from the perspective of the line of the file, and bash
does not inline the function.
A trick around it can be gotten with the following modification of your scripts.
---func-file----------------------
Line()
{
echo This is line "$MyLN" $@
}
#extra
#lines
#desired
#to
#show
#that
#execution
#not
#early, orig
#simply
#placed
#early
#in
#file
LineO()
{
echo This is line "$LINENO" $@
}
-------------------------
----main---------------------
#!/bin/bash
. ./func-file
MyLN=$LINENO Line ... it should be $LINENO
LineO ... it should be $LINENO
-------------------------
