Usage
lectl [-h|--help] [-v|--version] [-l|--extraline] [-s|--sans] [-e|--expired] [-u|--utc] [-m] [-p|--pre] [-f|--final] domainOptions
-h | --help [Default: false] shows the help file.
-v | --version shows the script version.
-l | --extraline [Default: false] adds extra line separator between found
certificates (when there are several certs with several
sans adding this extra line it's easier to read the output).
-s | --sans [Default: false] shows all domains included in the
certificate as SANs. If you don't use this option you will
only see the Common Name.
-e | --expired [Default: false] shows all certs issued for the specified
domain, including the certs that are already expired.
-u | --utc [Default: false] shows the dates in UTC (GMT) instead of
your machine time zone.
-m [Default: 100] searchs for more or less than 100 certificates
per domain OR subdomain. It means that if for example you use
option -m25 you could receive an output of max 50 certs (25 for
the domain and 25 for *.domain).
If this option is not used, lectl searchs only for last 100
certificates. If the option is used it searches by default
for last 1000 certificates.
If you want to search for more or less certificates, append
the number after the option with no spaces (Ex: -m500). If
you specify a number, then the option must be specified
independently.
Wrong: lectl -seulm500 domain.tld
Good: lectl -seul -m500 domain.tld
-p | --pre [Default: true] shows only logged pre certs.
-f | --final [Default: true] shows only logged final certs.Examples
