Tell me, is it possible to ask one character to perform a search and include the others that were found to check each of them in turn? Give me the right command to do this.

I want to insert my password from a text file and try one character at a time for an error, this may work.
Not sure exactly what you mean by try one character at a time. You have to test complete passwords... but do you mean you just want to check each character for error?

If so, then I believe the following might help. For instance, if you think your password was "ha$hc4t", but you think there might be a typo with the first character... you could try:

?aa$hc4t

This will try EVERY character (?a) at position 1... followed by "a$hc4t":

aa$hc4t
ba$hc4t
ca$hc4t
da$hc4t
ea$hc4t
fa$hc4t
...
etc etc

You could try that, and if not successful, you could try the 2nd char:

h?a$hc4t <--- "h" (test every character at position 2 with ?a) followed by "shcat":

ha$hc4t
hb$hc4t
hc$hc4t
hd$hc4t
he$hc4t
hf$hc4t



You can also create a ".hcmask" file, that includes all the masks you wanted to try...

Code: (example.hcmask)
?aa$hc4t
h?a$hc4t
ha?ahc4t
ha$?ac4t
ha$h?a4t
ha$hc?at
ha$hc4?a

Would try each of those masks, one after the other, exhausting all possible permutations before moving onto the next mask... you just use the file name in place of the mask in the commandline:
Code:
hashcat.exe -m 11300 -a 3 $bitcoin$96$**** example.hcmask
