Convert CSV to JSON

Find the package that installed a command

draw matrix using dot

Calculate the mean or average of a single column of numbers in a text file
single-column-numbers.txt is a text file with 22658 rows (numbers) in a single column. Each number can range from 0 to 134298679.533591 and the dot is for the decimals. This is done with perl because awk can't sum such high numbers.

List docker volumes by container

list block devices
Shows all block devices in a tree with descruptions of what they are.

Show biggest files/directories, biggest first with 'k,m,g' eyecandy
I use this on debian testing, works like the other sorted du variants, but i like small numbers and suffixes :)

Find the process you are looking for minus the grepped one
As an alternative to using an additional grep -v grep you can use a simple regular expression in the search pattern (first letter is something out of the single letter list ;-)) to drop the grep command itself.

Find files that are older than x days
Find files that are older than x days in the working directory and list them. This will recurse all the sub-directories inside the working directory. By changing the value for -mtime, you can adjust the time and by replacing the ls command with, say, rm, you can remove those files if you wish to.

Show only existing executable dirs in PATH using only builtin bash commands
Finds executable and existing directories in your path that can be useful if migrating a profile script to another system. This is faster and smaller than any other method due to using only bash builtin commands.
