Calculate 1**2 + 2**2 + 3**2 + ...

I can't put the last ^2 with seq, so I reverse it to delete the last +N. So for doing sum(N^2) you have to do sum((N+1)^2). Must be a better way.

Compute the numeric sum of a file

In the file data.txt there is a single column of numbers. Sed adds a "+" between lines and xargs prepares the output for bc. The "echo 0" is to avoid to have a "+" at the beginning of the line.

find out how much space are occuipied by files smaller than 1024K (sic) - improved

The original didn't use -print0 which fails on weird file names eg with spaces.

The original parsed the output of 'ls -l' which is always a bad idea.

find out how much space are occuipied by files smaller than 1024K

The command gives size of all files smaller than 1024k, this information, together with disk usage, can help determin file system parameter (e.g. block size) or storage device (e.g. SSD v.s. HDD).

Note if you use awk instead of "cut| dc", you easily breach maximum allowed number of records in awk.

Do quick arithmetic on numbers from STDIN with any formatting using a perl one liner.

Good for summing the numbers embedded in text - a food journal entry for example with calories listed per food where you want the total calories. Use this to monitor and keep a total on anything that ouputs numbers.
