This may be the future for methods that is alluded to in the reference
manual. One can currently read information from external files but the
implementation does not seem to allow the type of things we'd like to see.
For instance suppose I had a file like this.
/etc/profile,root,root,0644
/etc/cron.allow,root,root,0600
/etc/motd,root,root,6044
This is a neat way to separate the data and read from it. Readstringarray
almost allows use to do this except that the function uses the first entry
as the array name. This makes things impractical (or so it seems to me).
As Erlend mentioned a more Perlish way would be nice:
nwat...@tofrcpl58903 ~/tmp $ cat fileperms.txt
/etc/profile,root,root,0644
/etc/cron.allow,root,root,0600
/etc/motd,root,root,0644
nwat...@tofrcpl58903 ~/tmp $ cat foo.pl
#!/usr/bin/perl
use Data::Dumper;
open (FH, "<fileperms.txt") or die "cannot open file $!";
while (<FH>) {
chomp;
(
$files{"trg"},
$files{"usr"},
$files{"grp"},
$files{"mod"}
) =
split(',');
foreach $k (keys %files){
print "'$k' => string '$files{$k}';\n"
}
print "\n";
}
close FH;
nwat...@tofrcpl58903 ~/tmp $ ./foo.pl
'grp' => string 'root';
'trg' => string '/etc/profile';
'usr' => string 'root';
'mod' => string '0644';
'grp' => string 'root';
'trg' => string '/etc/cron.allow';
'usr' => string 'root';
'mod' => string '0600';
'grp' => string 'root';
'trg' => string '/etc/motd';
'usr' => string 'root';
