Linux Terminal: Get Memory, Temp, CPU & Make Them Useful!

[@LukeSmithxyz]

Some people have noticed that I chose to awk out a temperature that might be computer specific (i.e. in the ThinkPad section). You might want to awk out a temp in the coretemp section or whichever section your computer has. That might be more universal. You may also need to run `sudo sensors-detect` first.

Dude, gour videos are THE BEST linux videos on youtube. For someone who doesnt consider himself a linux youtuber, you destroy the rest! All other yourubers barely cover the basics of certain programs, concepts, commands, etc. Whay you do that makes all the difference is implement real, useful, interesting concepts for anyone ready to go to the next level and do useful things.

Use Firefox

[@dhiegov]

Well, not simple, but you could 1. grep the lines that have "chromium" 2. put them into a for loop that sums up the percentages (by awk'ing the second element, stripping the percent ("%") and summing the value to an accumulator) 3. concatenate this sum in what would be the process line again (like `cat "chromium" $sum`) 4. concatenate that resulting string back to the list of 9 more demanding processes and 5. sort it again Note that 1. because you are sorting again and the number of spaces that the concatenation in step 3 might be misaligned with the list that the ps gives you, you might as well get the ps list raw (without the ":15" attached to "cmd") and format it yourself with printf. 2. you would want to just do all this processing if any chromium process is one of your top 10 demanding, else just do like Luke does
