  • To get the CPU temperature continuously on the desktop

    There is no need for variables. I also added sleep to reduce cpu usage, however I didn't test it.

  • On Screen micro display for battery and CPU temperature. nifty, small, omnipresent

    My firefox overheats my cpu, sometimes above 90 degrees Celsius ( hence the name? ) To keep an eye on temperature, I put this command inside KAlarm ( a kind of cron) to be repeated every minute, for 5 seconds, color red ( default for osd_cat). Its pretty, ultra small, displays a micro 2 lines text on every desktop and over everything and do not steal focus or interrupt any task. I get the information passively, in the low profile bottom of the screen. Of course you can use it inside a terminal. Just do it: watch -n 60 'acpi -t | osd_cat -p bottom'

  • Use acpi and notify-send to report current temperature every five minutes.

    works best in a shell script run at startup. It will ping localhost once and output to null, after it does that, acpi is called for temperature in fahrenheit and piped through to another loop that feeds notify-send for a tooltip. After waiting five minutes, it will start over. Show Sample Output

    while ping -c 1 127.0.0.1 > /dev/null; do acpi -t -f | while read tem; do notify-send "$tem"; done; sleep 300; done

  • Battery real life energy vs predicted remaining plotted

    This time I added a print to reemaining energy, every minute, time stamped. The example shown here is complete and point to large discrepancies as time passes, converging to accuracy near the end. Show Sample Output

    echo start > battery.txt; watch -n 60 'date >> battery.txt ; acpi -b >> battery.txt'

  • To get the CPU temperature continuously on the desktop

    No need for a colon, and one less semicolon too. Also untested.

  • Check whether laptop is running on battery or cable

    This prints "Charging" or "Discharging". Obviously, this will indicate the status of the AC adapter. The awk part could be from 1-6. I removed the comma because it is useless when only looking at one element of the output array. See acpi(1) for more info.

  • Power Supply Triggered Alert

    Checks whether your power supply is still plugged in. If not it will trigger an alarm at maximum volume. Show Sample Output

Output entire line once per unique value of the first column
Removes duplicates in the specified field/column while outputting entire lines. An elegant command for processing tab (or otherwise) delimited data.

Run a command, redirecting output to a file, then edit the file with vim.
This is one of those 'nothing' shell functions ...which I use all the time. If the command contains spaces, it must be quoted, e.g. $ vimcmd 'svn diff' /tmp/svndiff.out If I want to keep the output of the command that I'm running, I use vimcmd. If I don't need to keep the output, I use this: $ vim

Put a console clock in top right corner
Gives not only date but also some interesting status about the System

quick integer CPU benchmark
This is a quick and dirty way to generate a (non-floating-point) CPU-bound task to benchmark. Adjust "20" to higher or lower values, as needed. As a benchmark this is probably a little less bogus than bogomips, and it will run anywhere 'bc' does.
