A few linux shell scripts that i use near-every day
clone - creates copy of $1 with orig_$1 name
fp - find process by name, PID etc.
fsd - find socket descriptor
lans - ifconfig all physical ethernet adapters
mounts - list phisical drive mounts
nag - cat any config file discarding comment lines
newsh - create $1.sh file and chmod it +x
vlans - ifconfig all VLAN vitrual interfaces
/bin/sh
Edit _install.sh for your needs and then:
./_install.sh
There is no cases in universe when this amazing scripts needs to be uninstalled ;)
