It takes both the password and group files and finds the next available UID and displays it. (No cats were harmed in the making of this script) #!/bin/bash awk -F":" '{ print $3 }' /etc/passwd > number_list awk -F":" '{ print $3 }' /etc/group >> number_list A=` sort -g number_list | tail -1` A=`expr $A + 1` echo "New Available UID is $A" Mail to My Friend , Home Page |
