The final script is account_list.sh that is going to print a summary of some account information on your system. We've been looking at the /etc/passwd file on and off. This script is going to parse that file to find and print the usernames for all non-system accounts. In addition, if the account has a non-standard (i.e., non-bash) shell, then the script will mark that username with an asterisk. In particular, when you look at a line of /etc/passwd, there are seven colon-delimited fields. The first is the username, the third is the user ID, and the seventh is the shell for that user. Your script must ignore all system accounts, which are accounts that have a user ID of less than 1000. If the account has an ID of at least 1000, then you will print the username of that account. If the shell for that account is not /bin/bash, then also print an asterisk after the name to indicate that it is non-standard. Of course, you may need to build in to the script to read from /etc/passwd with a while loop (You may not need a loop if you would like to learn awk more by yourself). Then you should be using awk to extract the appropriate fields from each line. while read line; do Here is a hint: # use awk here done
