I have a perl script that opens a file and parses thru a file replacing a search string.
I need to modify the code to take a list of file names and then parse thru each file. Instead of taking the file name from the command line.
#!/usr/bin/perl
use strict;
use warnings;
my($copy) = "$ARGV[0].bak";
copy($ARGV[0], $copy) or die "File cannot be copied. \n";
open(INPUT,"$copy") or die 'Cannot open file: $!\n';
open(OUTPUT,">$ARGV[0]");
my($replacePattern1) = "foo1";
my($searchPattern1) = "bar1";
my($replacePattern2) = "foo2";
my($searchPattern2) = "bar2";
my($replacePattern3) = "foo3";
my($searchPattern3) = "bar3";
my($pattern) = 0;
while (<INPUT>) {
if ($_ =~ s/$searchPattern1/$replacePattern1/g) {
$pattern = 1;
}
elsif ($_ =~ s/$searchPattern2/$replacePattern2/g) {
$pattern = 2;
}
elsif ($_ =~ s/$searchPattern3/$replacePattern3/g) {
$pattern = 3;
}
print OUTPUT $_;
}close INPUT;
close OUTPUT;
unlink($copy);
how do I modify this code?
