如何使用此Perl腳本？

Question

我在網上發現了這個Perl腳本，但我不知道如何使用它。當我運行它時，它會打開一個空的終端。我不知道該如何投入終端才能使其工作。

該腳本可以在這裏找到：http://www.ve3syb.ca/software/gimp/script-update.pl

非常感謝你的幫助。

好，在腳本的幫助下，文中說的：

print "Usage: $0 [-h|--help|-from xx|-to yy]\n"; 
    print "  -from xx Script was written for version xx of GIMP\n"; 
    print "  -to yy Output script for use with version yy of GIMP\n"; 
    print "\n"; 
    print "GIMP version number should be one:\n"; 
    print "  10, 12, 20, 22, 24, or 26\n"; 
    print "\n"; 
    print "  The script to be updated is read from stdin.\n"; 
    print "  The updated script is written to stdout.\n"; 
    print "\n"; 

調用它像這樣：

./script.pl -from XX -to YY <input> output

使用說明在腳本中，它們告訴你如何使用它。尤其要注意的是，要從stdin中讀取要更新的腳本的位 - 所以您可能需要重定向或管理腳本。

if ($arg eq "-h" || $arg eq "--help") 
    { 
     print "Usage: $0 [-h|--help|-from xx|-to yy]\n"; 
     print "  -from xx Script was written for version xx of GIMP\n"; 
     print "  -to yy Output script for use with version yy of GIMP\n"; 
     print "\n"; 
     print "GIMP version number should be one:\n"; 
     print "  10, 12, 20, 22, 24, or 26\n"; 
     print "\n"; 
     print "  The script to be updated is read from stdin.\n"; 
     print "  The updated script is written to stdout.\n"; 
     print "\n"; 
     exit; 
    }
