What is the output of: lc_all=c pacman -v|tail -n3|base32|head -1 ? *

The output of the command lc_all=c pacman -v|tail -n3|base32|head -1 ? * is a base32 encoded string.

Let’s break down the command step by step:

1. lc_all=c pacman -v is a command to list the verbose output of the pacman command. The lc_all=c part sets the locale to “C” which ensures the output is in English for easier parsing.
2. |tail -n3 takes the output of the previous command and only selects the last 3 lines.
3. |base32 performs a base32 encoding on the selected output.
4. |head -1 selects only the first line of the base32 encoded output.

Therefore, the final output of the command is a single line of base32 encoded text.

Here’s an example to illustrate the process:

    
      $ lc_all=c pacman -v | tail -n3 | base32 | head -1
