Well, better let's look at the example.
First, let's make the sequence of 62 characters.
Now we have 62 characters per line (Excluding the first line with the character $'\n').
Let's see how many combinations of 2 characters are possible.
Subtract 1 ($'\n') from the resulting value, and we get the number 3844 variants.
Add chili pepper to three and get...
And the time spent by my laptop will be
And the last option of the four elements. Prevent you from even running this command!
for the time being the command almost paralyzed my laptop.
And this is only a combination of 4 items from 62
Thanks for attention.

SYNOPSIS
string [suffix]
[string]
DESCRIPTION
deletes any prefix ending in and the suffix (if present in string) from string, and prints the result on the standard output. If string
consists entirely of slash characters, string is set to a single slash character. If there are any trailing slash characters in string,
they are removed. If the suffix operand is present but not identical to the characters remaining in string, but it is identical to a suf-
fix of the characters remaining in string, the suffix is removed from string. is normally used inside command substitution marks within
shell procedures.
delivers all but the last level of the path name in string. If string does not contain a directory component, returns indicating the cur-
rent working directory.
EXTERNAL INFLUENCES
Environment Variables
determines the interpretation of string and, in the case of basename, suffix as single and/or multi-byte characters.
If is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty vari-
able. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization
variable contains an invalid setting, and behave as if all internationalization variables are set to "C". See environ(5).
International Code Set Support
Single- and multi-byte character code sets are supported.
