With bash there is no need for any external command:

Code:
#!/bin/bash
file=$1

mapfile -t xx < "$file"
n=${#xx[@]}
printf "%s\n" "${xx[@]:1:n-2}"

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 ATTRIBUTES
