The output of the given command can be explained as follows:
$ lc_all=c pacman -v # Set the value of the LC_ALL environment variable to 'c' and execute the 'pacman -v' command [output of 'pacman -v' command] $ lc_all=c pacman -v | tail -n3 # Pipe the output of 'pacman -v' command to 'tail -n3' command [output of 'tail -n3' command] $ lc_all=c pacman -v | tail -n3 | base32 # Pipe the output of 'tail -n3' command to 'base32' command [output of 'base32' command] $ lc_all=c pacman -v | tail -n3 | base32 | head -1 # Pipe the output of 'base32' command to 'head -1' command [output of 'head -1' command]
Therefore, the final output will be as per the output of the last command in the command chain.
For example, if the output of the last command is “WLYW6A======”, then the final output will be “WLYW6A======”.
