MViewは、シーケンスデータベース検索またはマルチアライメントの結果を抽出および再フォーマットし、オプションでWebページレイアウト用のHTMLマークアップを追加するコマンドラインユーティリティである。 一般的な形式に変換するためのフィルターとしても使用できる。

1行目をperlのパスに修正する。
#!/usr/bin/perl
ここではmview-1.66のフォルダを/usr/local/に移動し、25行を以下のように修正した。
use lib '/usr/local/mview-1.66/lib';
> /usr/local/mview-1.66/bin/mview -h
$ /usr/local/mview-1.66/bin/mview -h
usage: mview [options] [file...]
Option names and parameter values can generally be abbreviated. Alternative
parameter values are listed in braces {}, followed by the default value in
square brackets [].
Some options take multiple arguments which must be supplied as a comma
separated list, like '1,8,9,10'. Subranges are allowed, so you could also
write that as '1,8:10' or even '1,8..10'. Any argument must be quoted if it
contains whitespace or a wildcard that might be expanded by the shell.
Option processing can be terminated using '--'.
