bc doesn't support arrows and history.
Use GNU bc for that feature, eg. gbc from blastwave.

k5srvutil
K5SRVUTIL(1) General Commands Manual K5SRVUTIL(1)
NAME
k5srvutil - host key table (keytab) manipulation utility
SYNOPSIS
k5srvutil operation [ -i ] [ -f filename ]
DESCRIPTION
k5srvutil allows a system manager to list or change keys currently in his keytab or to add new keys to the keytab.
Operation must be one of the following:
list lists the keys in a keytab showing version number and principal name.
change changes all the keys in the keytab to new randomly-generated keys, updating the keys in the Kerberos server's database to match
by using the kadmin protocol. If a key's version number doesn't match the version number stored in the Kerberos server's data-
base, then the operation will fail. The old keys are retained so that existing tickets continue to work. If the -i flag is
given, k5srvutil will prompt for yes or no before changing each key. If the -k option is used, the old and new keys will be dis-
played.
delold Deletes keys that are not the most recent version from the keytab. This operation should be used some time after a change opera-
tion to remove old keys. If the -i flag is used, then the program prompts the user whether the old keys associated with each
principal should be removed.
delete deletes particular keys in the keytab, interactively prompting for each key.
In all cases, the default file used is /etc/krb5.keytab file
unless this is overridden by the -f option.
k5srvutil uses the kadmin program to edit the keytab in place. However, old keys are retained, so they are available in case of failure.
