Windows で Cygwin などが入ってなくて、find とか xargs とかない場合に使う Perl スクリプトを書いてみた。
#!/usr/bin/env perl use strict; use warnings; use File::Find; use File::Basename; &print_usage if ($#ARGV < 0); find(\&process, $ARGV[0]); sub process { my $org_filename = $_; my $new_filename = "$org_filename.tmp"; return unless -f $org_filename; open (my $IN, "<", $org_filename) or warn "cannot open $org_filename because $! \n"; open (my $OUT, ">", $new_filename) or warn "cannot create $new_filename because $! \n"; while (<$IN>) { s/"//g; print $OUT $_; } close ($IN); close ($OUT); rename($org_filename, "$org_filename.org") or warn "cannot rename $org_filename because $! \n"; rename($new_filename, $org_filename) or warn "cannot rename $new_filename because $! \n"; } sub print_usage { my $script_name = basename($0); print "$script_name: missing argument\n"; print "Usage : perl $script_name directory\n"; print "Example: perl $script_name ./log\n"; exit(1); } __END__
