This is somewhat dependent on the shell you use. What follows is valid for bash (and other recent shells).
`...` is the old, deprecated form of what is called "command substitution": it supplies the command's stdout in lieu of the command, to be assigned to
lines in this case.
man bash:
Quote:
Command Substitution
Command substitution allows the output of a command to replace the command name. There are two forms:
$(command)
or
`command`
The second line references the fourth element of the array
lines, to be assigned to the EDate variable. It probably will stay empty, as
lines, defined in the code line above, is a simple variable, not an array.

gst-complete-0.8
gst-complete-0.8(1) User Commands gst-complete-0.8(1)
NAME
gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines
SYNOPSIS
complete -Cgst-complete-0.8 gst-launch
gst-complete [--gst-list-mm] [--gst-mm=string] [--print]
DESCRIPTION
gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
gst-launch command lines.
You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.
gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.
OPTIONS
The following options are supported by gst-complete-0.8 and gst-complete:
--help Display detailed usage message. You can also use -? to specify this option.
The following options are supported by gst-complete only:
--gst-list-mm List found major/minor versions. This option displays the versions that are available.
--gst-mm=string Force major/minor version. This option enables you to specify a specific version to run, if you do not want to run the
default version.
--print Print wrapped command line. This option displays the command that will be run, and then runs the command.
EXAMPLES
Example 1: Generating the Registry of Available Plugins by Running gst-compprep
Run the following command in your .bash_profile or other appropriate place:
example% complete -C gst-complete-0.8 gst-launch
Example 2: Running the Wrapper Script and Displaying the Command Name
example% gst-complete --print
/usr/bin/gst-complete-0.8
FILES
The following files are used by this application:
/usr/bin/gst-complete-0.Executable for bash completion for gst-launch
/usr/bin/gst-complete Wrapper script that runs the latest installed version of gst-complete-X.X
