ps listing gives you all the processes that are running. If more than one instance of Inst.sh is running, you plan to kill the other instances ? Better would be to introduce a lock file concept rather than killing processes.

ps x | grep '[I]nst.sh' gives you the pid(s) of Inst.sh

See the lock file getting used in how to detect my script is already running and How to check if another instance of the process is running

JIGDO-LITE(1)															     JIGDO-LITE(1)

NAME
jigdo-lite - Download jigdo files using wget SYNOPSIS
jigdo-lite [ URL ] DESCRIPTION
See jigdo-file(1) for an introduction to Jigsaw Download. Given the URL of a `.jigdo' file, jigdo-lite downloads the large file (e.g. a CD image) that has been made available through that URL. wget(1) is used to download the necessary pieces of administrative data (contained in the `.jigdo' file and a corresponding `.template' file) as well as the many pieces that the large file is made from. The jigdo-file(1) utility is used to reconstruct the large file from the pieces. `.jigdo' files that contain references to Debian mirrors are treated specially: When such a file is recognized, you are asked to select one mirror out of a list of all Debian mirrors. If URL is not given on the command line, the script prompts for a location to download the `.jigdo' file from. The following command line options are recognized: -h --help Output short summary of command syntax. -v --version Output version number. --scan FILES Do not ask for "Files to scan", use this path. --noask Do not ask any questions, instead behave as if the user had pressed Return at all prompts. This can be useful when running jigdo- lite from cron jobs or in other non-interactive environments. SEE ALSO
jigdo-file(1), jigdo-mirror(1), wget(1) (or `info wget') CD images for Debian Linux can be downloaded with jigdo <URL:http://www.debian.org/CD/jigdo-cd/>. AUTHOR
Jigsaw Download <URL:http://atterer.net/jigdo/> was written by Richard Atterer <jigdo atterer.net>, to make downloading of CD ROM images for the Debian Linux distribution more convenient. 19 May 2006 JIGDO-LITE(1)
