Check These Out
from my bashrc ;)
Replace 'csv_file.csv' with your filename.
Loop is needed if you have more then one card.
I tried out on my Mac, jot to generate sequence ( 0,25,50,..), you can use 'seq' if it is linux to generate numbers, need curl installed on the machine, then it rocks.

This command could seem pretty pointless especially when you can get the same result more easily using the rpm builtin queryformat, like:
$ rpm -qa --qf "%{NAME} %{VERSION} %{RELEASE}.%{ARCH}\n" | sort | column -t
but nonetheless I've learned that sometimes it can be quite interesting trying to explore alternative ways to accomplish the same task (as Perl folks like to say: There's more than one way to do it!)
I usually have 5 or more ssh connections to various servers, and putting this command in my .bash_profile file makes my putty window or x terminal window title change to this easily recognizable and descriptive text. Includes the username, group, server hostname, where I am connecting from (for SSH tunneling), which device pts, current server load, and how many processes are running.
You can also use this for your PROMPT_COMMAND variable, which updates the window title to the current values each time you exec a command.
I prefix running this in my .bash_profile with
$ [[ ! -z "$SSH_TTY" ]] &&
which makes sure it only does this when connecting via SSH with a TTY.
Here's some rougher examples from http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html
$ # If set, the value is executed as a command prior to issuing each primary prompt.
$ #H=$((hostname || uname -n) 2>/dev/null | sed 1q);W=$(whoami)
$ #export PROMPT_COMMAND='echo -ne "\033]0;${W}@${H}:${PWD/#$HOME/~} ${SSH_TTY/\/dev\//} [`uptime|sed -e "s/.*: \([^,]*\).*/\1/" -e "s/ //g"`]\007"'
$ #PROMPT_COMMAND='echo -ne "\033]0;`id -un`:`id -gn`@`hostname||uname -n 2>/dev/null|sed 1q` `command who -m|sed -e "s%^.* \(pts/[0-9]*\).*(\(.*\))%[\1] (\2)%g"` [`uptime|sed -e "s/.*: \([^,]*\).*/\1/" -e "s/ //g"` / `command ps aux|wc -l`]\007"'
$ #[[ -z "$SSH_TTY" ]] || export PROMPT_COMMAND
$ #[[ -z "$SSH_TTY" ]] && [[ -f /dev/stdout ]] && SSH_TTY=/dev/stdout
And here's a simple function example for setting the title:
$ function set_window_title(){ echo -e "\033]0; ${1:
[email protected]$HOST - $SHLVL} \007"; }

You would need pwgen installed first, on ubuntu you can get it by apt-get
