Returns the IP, broadcast, and subnet mask of your interfaces absent any other extraneous info. I know it's a bit lame, but I've created an alias for this when I *quickly* want to know what a system's IP is. Small amounts of time add up :) Show Sample Output

I don't like doing a massive sort on all the directory names just to get a small set of them. the above shows a sorted list of all directories over 1GB. use head as well if you want. du's "-x" flag limits this to one file system. That's mostly useful when you run it on "/" but don't want "/proc" and "/dev" and so forth. Remember though that it will also exclude "/home" or "/var" if those are separate partitions. the "-a" option is often useful too, for listing large files as well as large directories. Might be slower.

The above is OK if you not worried about security, as per sshpass man pages: " The -p option should be considered the least secure of all of sshpass's options. All system users can see the password in the command line with a simple "ps" command." So, instead what I do is use the -e option: " -e The password is taken from the environment variable "SSHPASS"."

In a multiple PostgreSQL server environment knowing the servers version can be important. Note that psql --version returns just the local psql apps version which may not be what you want. This command dumps the PostgreSQL servers version out to one line. You may need to add more command line options to the psql command for your connection environment. Show Sample Output
