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.
