Die without textoutput?
|
|
| gustav@varupiraten.se 2005-10-28, 3:55 am |
| Hi!
When die is used, there is message something like:
x doesn't exist as an environment variable
Died at lsh.pl line 510, <STDIN> line 6.
Childprocess complete
I just want the current process to die without giving any output to
screen, something like this:
x doesn't exist as an environment variable
Childprocess complete
Is there any substitue for the die-command to achieve this?

Isn't that output to the screen? Did you read the documentation for die where
it explains the different forms of output and alternatives to die?
perldoc -f die
Do you have any questions about what's in the documentation?
It is hard to diagnose code problems without seeing any code.

Yes, but I don't want any output to the screen! Is this possible to achieve?
I'd like something like pseduo..
die <No output to screen, just die>
/G

| hi,
you can redefined the $SIG{__DIE__} handle to do that.
such as:
$SIG{__DIE__}=\&yourdie;
sub yourdie{
...
die;
}

Or, to avoid a second die:
chomsky ~/ramsch $ perl -le '$SIG{__DIE__}=sub {exit(1)}; \
die "explore the reason yourself"'
chomsky ~/ramsch $ echo $?
1
# you will have an exit code of 1 instead of die output.

| Do you mean that you don't want the line number and file evealed?
Llama said,
If you don't want the line number and file revealed,
make sure that the dying words have a newline on the end.
That is, another way you could use die is in a line like this,
with a trailing newline:
die "Not enough arguments\n" if @ARGV < 2;
If there aren't at least two command-line arguments,
that program will say so and quit.
It won't include the program name and line number.
