an alternative also is, if you prefer to use as much as less modules possible:
#!/usr/bin/perl
use strict;
no warnings;
foreach my $in (@ARGV){
my($copy) = "$in.bak";
copy($in, $copy) or die "File cannot be copied. \n";
open(INPUT,"$copy") or die 'Cannot open file: $!\n';
open(OUTPUT,">$in");
my($replacePattern1) = "foo1";
...
}
or if the files are in a dir then use the
readdir function, collect all the files from the dir and loop over them like in the example before
opendir(DIR, $ARGV[0]) || die "i died for no reason ;)\n";
foreach (readdir DIR){
#repeat like above
#watch out for defining the right path to dir and when looping re-ty
+pe the fool path to your dir, like:
# open (FILE, ">", "$ARGV[0]/$_") || die "i died for no reason ;)\n"
}
