In fact, I've still got no chance to understand what you are doing without samples of the input files. But some comments:
- don't redirect into the file that you use as input; the redirection takes precedence and truncates the input file BEFORE it can be read.
- with a smart regex you can have ALL those sed commands in one single command.
- Why don't you save those sed results in a variable that can be reused later in need be?
- Why do you use sed at all? Use bash's parameter expansion capabilities on $line.
- Not sure if you really want to call that .sh script for every line in your input file.

NAME
update-desktop-database - Desktop file caching utility
SYNOPSIS
update-desktop-database [--help] [--verbose] [--quiet] [filepath]
DESCRIPTION
update-desktop-database creates cache files for desktop file MIME type mapping for improved MIME lookup performance.
It expects to be given the path to a directory or directories containing a number of application installed .desktop files, e.g.
/usr/share/applications, and writes a mime-info.cache containing cached information about the MIME types that each application can handle.
If no directory is provided, this utility will use a default directory list as specified in the FreeDesktop MIME specification. This cache
file is used to avoid a lot of system call and disk seek overhead in a number of applications.
OPTIONS
The following options are supported:
-?, --help Show help options.
-v, --verbose Turn on verbose output.
-q, --quiet Do not provide any output.
OPERANDS
The following operands are supported:
filepath The path to a directory or directories containing a number of application installed .desktop files.
EXIT STATUS
The following exit values are returned:
0 Application exited successfully
1 Application exited with failure
FILES

/usr/bin/update-desktop-databaseThe command-line executable for the application.
/usr/share/applications System desktop file directory
