Re: Making perl script running under bash cygwin

 Why?

Cannot say the exact raeson, but i left out the 'or die' and it works.
#!/usr/bin/perl

$args = perl -i.orig -pe \'s!/home/ftp!/!g\' /etc/passwd;
system($args);

Maybe some native english speaker has a better understanding of this
part of perlrun.pod:

   -p   causes Perl to assume the following loop around your
program, which makes it iterate over filename argu­
ments somewhat like sed:

  LINE:
while () {
... # your program goes here
} continue {
print or die -p destination: $!\n;
}

If a file named by an argument cannot be opened for
some reason, Perl warns you about it, and moves on to
the next file.  Note that the lines are printed auto­
matically.  An error occurring during printing is
treated as fatal.  To suppress printing use the -n
switch.  A -p overrides a -n switch.

BEGIN and END blocks may be used to capture con­
trol before or after the implicit loop, just as in
awk.

RE: Making perl script running under bash cygwin

[Robinow, David]

system returns 0. 'system(...) or die' should always die.  Does it run the
command first?
  Does this have anything to do with cygwin? i.e., does it perform
differently on other systems?
