| # This script can be used to install the AWS CLI in $HOME/.local/ rather than global | |
| # Why? Because then we don't have to keep using sudo needlessly. | |

| # It creates a choices.xml which the pkg installer uses to select the correct path. | |
| # The binaries are then linked to the $HOME/.local/bin folder - make sure this is in your $PATH | |

| # Far better alternative to VLOOKUP | |
| # Works in both Excel and Google Sheets | |
| # VLOOKUP is _NOT_ case-sensitive and doesn't handle situations where the return value is in a column BEFORE the lookup. | |
| # This uses a table called Table1 with Name and Age Columns, with the lookup being in cell A1 | |
| =INDEX(Table1[Name], MATCH(TRUE, EXACT(A1, Table1[Age]), 0)) | |
| # The following does the same but it finds text ANYWHERE inside the cell, rather than an exact value. | |

A Task Definition is a collection of 1 or more container configurations. Some Tasks may need only one container, while other Tasks may need 2 or more potentially linked containers running concurrently.
The Task Definition allows you to specify things like:
| # https://powershell.one/tricks/filesystem/finding-duplicate-files | |
| function Find-PSOneDuplicateFile | |
| { | |
| <# | |
| .SYNOPSIS | |
| Identifies files with duplicate content | |
| .DESCRIPTION | |
| Returns a hashtable with the hashes that have at least two files (duplicates) |
