Or is there a better way to achieve this ?
Here's an idea:

Code:
$ 
$ 
$ cat file.txt
/usr/bin/1234.xcf
/usr/bin/3456.xcf
/usr/bin/7897.xcf
/usr/bin/2345.xcf
$ 
$ 
$ FILE="/usr/bin/7897.xcf"
$ 
$ grep "$FILE" file.txt
/usr/bin/7897.xcf
$ 
$

MojoMojo::Formatter::File(3pm)				User Contributed Perl Documentation			    MojoMojo::Formatter::File(3pm)

NAME

       MojoMojo::Formatter::File - format file as XHTML

DESCRIPTION

       This formatter will format the file argument as XHTML.

       Usage: {{file TYPE filename}}

	      {{file Text uploads/Files/test.txt}}

       TYPE is a plugin present in Formatter/File/ directory.

       Currently there are only three: Pod, DocBook and Text

       The plugin TYPE format only the file which the extension match with 'can_format' method. Respectively pod, xml and txt for existing
       plugins.

       For security reasons the path of file must be include in 'whitelisting' directory. You can use path_to(DIR) to describe directory in
       mojomojo.conf:

       Just an example to view the test pod file t/var/files/test.pod :

       Add this to mojomojo.conf :

       <Formatter::Dir>
	   prefix_url /myfiles
	   whitelisting __path_to(t/var/files)__ </Formatter::Dir>

       To see the pod content formatted in xhtml, write in the text area:

       {{file Pod path_to(t/var/files)test.pod}}

       To show recursively all files of directory see script/util/dir2mojomojo.pl script. To test it:

       # start mojomojo

       ./script/mojomojo_server.pl

       # run dir2mojomojo script

       ./script/util/dir2mojomojo.pl --dir=~/dev/mojomojo/t/var/files/ --url=/myfiles

       Connect to http://server:3000/myfiles/

METHODS

       format_content_order
	   Format order can be 1-99. The File formatter runs on 92.

       format_content
	   Calls the formatter. Takes a ref to the content as well as the context object.

       plugin
	   Return the plugin to use with file attachment

       format

       checkplugin
	   Return 0 if plugin exist

       checkfile
