rename the specific file with current time stamp using perl script for windows -


i using below script rename renaming file end sta.i need rename file starts krat or trat.

#!/usr/local/bin/perl  use strict;  use warnings;  use file::copy;   $directory = 'c:\users\desktop';   chdir($directory) or die "can't chdir $directory $!";  opendir(dir, $directory) || die "couldn't opendir: $!\n";   @files = grep { $_ ne '.' && $_ ne '..' } readdir dir;   foreach(@files) {      print $_,"\n";      $newname = $_;       $newname =~ s/sta$/t00/g;      print "renaming: $_ -> $newname \n";       rename($_, $newname);   }

some minor changes script.

use strict;  use warnings;  use file::copy;   $directory = 'c:\users\rajkunal_aps\desktop';  chdir($directory) or die "can't chdir $directory $!";  opendir(dir, $directory) || die "couldn't opendir: $!\n";   @files = grep { $_ ne '.' && $_ ne '..' } readdir dir;   foreach(@files) {      print $_,"\n";      $newname = $_;     if ($newname =~ /^krat/ || $newname =~ /^trat/ ) {     $newname =~ s/sta/t00/g;     print "renamed: $newname $_ \n";      rename($_, $newname);      } }

result

trat.aud.sta -> trat.aud.t00 stat.aud.sta -> no changes krat.eud.sta -> krat.eud.t00

explanation:

the problem script searching file ends sta , rename t00. instead should search files match.

so this, search see if beginning of line matches either krat or trat using /^krat/ , /^trat/ in if statement. if find matches, search , replace of sta t00 using s/sta/t00//g;
