Re: bash variable expansion moment

You could pass the value of $LINENO to Line() as a function argument:

Here's the one file (func-file):
-------------------------
Line()
{
echo This is line $@
}
-------------------------

That one is called by this one:
-------------------------
#!/bin/bash

. ./func-file

Line $LINENO
------------------------

Macintosh-5:/tmp joshuagimer$ cat func-file
Line()
{
echo This is line $@
}
Macintosh-5:/tmp joshuagimer$ cat test.sh
#!/bin/bash

. ./func-file

Line $LINENO
Macintosh-5:/tmp joshuagimer$ bash test.sh
This is line 5

Thanks

It's half a nice Saturday later and many attempts have brought no

I'm trying to write a function which, when called from one function
execute in another.  In itself, that's not the problem.  Rather, there's
one built-in variable which is evaluated in the function definition and
it's value is then set (too early).

Here's the one file (func-file):
-------------------------
Line()
{
echo This is line "$LINENO" $@
}
-------------------------

That one is called by this one:
-------------------------
#!/bin/bash

. ./func-file

Line ... it should be $LINENO
------------------------

I want the function Line to show the line number in the second file
where it's executed, not the line number from the sourced function.

Any mavens got the skinny on this?
