Era tan obvio? pense en mencionar algo de El tigrito o Las Gemelas, pero decidi que algo de Espankear seria mas chistoso. Eres alguien bien dificil de encontrar sabes?

I’m downloading 11.1 Live CD right now. I’ve already (accidentally) made the DVD installation disk. But, I want to try out the Live CD version 1st.

I live in Layton.

Just some simple comments about your script:
1. In many of your printf statements you close the quoted string to print a variable. This is unnecessary. Bash will expand all variables that are inside double-quotes.

So this:
printf ” Groups:\t”$MYGROUPS”\n”
Can become this:
printf ” Groups:\t$MYGROUPS\n”

Slightly more readable, and 2 fewer characters.

2. You use “cat” twice, and neither time is necessary. Most GNU commands can take filenames as arguments, or you can simply use the “< filename” to input content on stdin. http://sial.org/howto/shell/useless-cat/

So this:
cat /etc/resolv.conf | tail -n 4 …
Becomes this:
tail -n 4 /etc/resolv.conf …

and this:
cat /proc/cpuinfo | grep “model name\|processor” …
becomes this:
grep “model name\|processor” /proc/cpuinfo …

This saves additional command forking and keeps code succinct.

Other than these two extremely minor points, you are doing a great job. It’s really cool. I might just use it in a .bashrc or something like that.

I suggest you also add the temperature of the processor. I find this quite useful on a laptop. The basic solution is

cat /proc/acpi/thermal_zone/THM/temperature

which displays:

temperature: 57 C
