The notable boundary-pusher in the iPadOS/iOS local command line.
There are now quite a few terminal emulator-esque apps on the App Store, but I’ve been using a-Shell since it was joined only by Blink (from which it was forked) and iSH. As it was then, a-Shell remains the only one of these with which one can actually accomplish command…

SYNOPSIS

See the built-in command description in the appropriate shell manual page.

DESCRIPTION

Shell builtin commands are commands that can be executed within the
running shell’s process.
Note that, in the case of
csh(1)
builtin commands, the command is executed in a subshell if it occurs as
any component of a pipeline except the last.

If a command specified to the shell contains a slash
/’,
the shell will not execute a builtin command, even if the last component
of the specified command matches the name of a builtin command.
Thus, while specifying
echo
causes a builtin command to be executed under shells that support the
echo
builtin command,
specifying
/bin/echo
or
./echo
does not.

While some builtin commands may exist in more than one shell, their
operation may be different under each shell which supports them.
Below is a table which lists shell builtin commands, the standard shells
that support them and whether they exist as standalone utilities.

Only builtin commands for the
csh(1)
and
sh(1)
shells are listed here.
Consult a shell’s manual page for
details on the operation of its builtin commands.
Beware that the
sh(1)
manual page, at least, calls some of these commands
“built-in commands”
and some of them
“reserved words”.
Users of other shells may need to consult an
info(1)
page or other sources of documentation.

Commands marked

WHICH(1) – General Commands Manual

NAME

which – locate a program file in the user’s path

SYNOPSIS

which
[-as]
program …

DESCRIPTION

The
which
utility
takes a list of command names and searches the path for each executable
file that would be run had these commands actually been invoked.

The following options are available:

-a

List all instances of executables found (instead of just the first one
of each).

-s

No output, just return 0 if all of the executables are found, or 1 if
some were not found.

Some shells may provide a builtin
which
command which is similar or identical to this utility.
Consult the
builtin(1)
manual page.

SYNOPSIS

See the built-in command description in the appropriate shell manual page.

DESCRIPTION

Shell builtin commands are commands that can be executed within the
running shell’s process.
Note that, in the case of
csh(1)
builtin commands, the command is executed in a subshell if it occurs as
any component of a pipeline except the last.

If a command specified to the shell contains a slash
/’,
the shell will not execute a builtin command, even if the last component
of the specified command matches the name of a builtin command.
Thus, while specifying
echo
causes a builtin command to be executed under shells that support the
echo
builtin command,
specifying
/bin/echo
or
./echo
does not.

While some builtin commands may exist in more than one shell, their
operation may be different under each shell which supports them.
Below is a table which lists shell builtin commands, the standard shells
that support them and whether they exist as standalone utilities.

Only builtin commands for the
csh(1)
and
sh(1)
shells are listed here.
Consult a shell’s manual page for
details on the operation of its builtin commands.
Beware that the
sh(1)
manual page, at least, calls some of these commands
“built-in commands”
and some of them
“reserved words”.
Users of other shells may need to consult an
info(1)
page or other sources of documentation.

Commands marked
No**
under
External
do exist externally,
but are implemented as scripts using a builtin command of the same name.

security(1) – General Commands Manual

NAME

security – Command line interface to keychains and Security framework

SYNOPSIS

security
[-hilqv]
[-p prompt]
[command]
[command_options]
[command_args]

DESCRIPTION

A simple command line interface which lets you administer keychains,
manipulate keys and certificates, and do just about anything the
Security framework is capable of from the command line.

By default
security
will execute the
command
supplied and report if anything went wrong.

If the
-i
or
-p
options are provided,
security
will enter interactive mode and allow the user to enter multiple commands on stdin. When EOF is read from stdin
security
will exit.

Here is a complete list of the options available:

-h

If no arguments are specified, show a list of all commands. If arguments are provided, show usage for each the specified commands. This option is essentially the same as the
help
command.

-i

Run
security
in interactive mode. A prompt
(security>
by default)
will be displayed and the user will be able to type commands on stdin until an EOF is encountered.

-l

Before
security
exits, run

/usr/bin/leaks -nocontext

on itself to see if the command(s) you executed had any leaks.

-p prompt

This option implies the
-i
option but changes the default prompt to the argument specified instead.

-q

Will make
security
less verbose.

-v

Will make
security
more verbose.

SECURITY COMMAND SUMMARY

security
provides a rich variety of commands
(command
in the
SYNOPSIS), each of which often has a wealth of options, to allow access to
the broad functionality provided by the Security framework. However,

Specify certificate to delete by its common name

-Z hash

Specify certificate to delete by its SHA-256 (or SHA-1) hash

-t

Also delete user trust settings for this certificate

The certificate to be deleted must be uniquely specified either by a
string found in its common name, or by its SHA-256 (or SHA-1) hash.

delete-identity
[-h]
[-c name]
[-Z hash]
[-t]
[keychain…]
Delete a certificate and its private key from a keychain. If no
keychain arguments are provided, the default search list is used.

-c name

Specify certificate to delete by its common name

-Z hash

Specify certificate to delete by its SHA-256 (or SHA-1) hash

-t

Also delete user trust settings for this identity certificate

The identity to be deleted must be uniquely specified either by a
string found in its common name, or by its SHA-256 (or SHA-1) hash.

set-identity-preference
[-h]
[-n]
[-c identity]
[-s service]
[-u keyUsage]
[-Z hash]
[keychain…]
Set the preferred identity to use for a service.

-n

Specify no identity (clears existing preference for the given service)

-c identity

Specify identity by common name of the certificate

-s service

Specify service (may be a URL, RFC822 email address, DNS host, or other name) for which this identity is to be preferred

-u keyUsage

Specify key usage (optional)

-Z hash

Specify identity by SHA-256 (or SHA-1) hash of certificate (optional)

The identity is located by searching the specified keychain(s) for a certificate whose common name contains
the given identity string. If no keychains are specified to search, the default search list is used. Different
identity preferences can be set for individual key usages. You can differentiate between two identities which contain
the same string by providing a SHA-256 (or SHA-1) hash of the certificate in addition to, or instead of, the name.

PARTIAL PATHS AND WILDCARDS

Prior to 10.5.4, identity preferences for SSL/TLS client authentication could only be set on a per-URL basis. The
URL being visited had to match the service name exactly for the preference to be in effect.

In 10.5.4, it became possible to specify identity preferences on a per-server basis, by using
a service name with a partial path URL to match more specific paths on the same server. For
example, if an identity preference for “https://www.apache-ssl.org/” exists, it will be in effect for
“https://www.apache-ssl.org/cgi/cert-export”, and so on. Note that partial path URLs must end with a trailing
slash character.

Starting with 10.6, it is possible to specify identity preferences on a per-domain
basis, by using the wildcard character ‘*’ as the leftmost component of the service name. Unlike SSL wildcards,
an identity preference wildcard can match more than one subdomain. For example, an identity preference for
the name “*.army.mil” will match “server1.subdomain1.army.mil” or “server2.subdomain2.army.mil”. Likewise,
a preference for “*.mil” will match both “server.army.mil” and “server.navy.mil”.

KEY USAGE CODES

 0 - preference is in effect for all possible key usages (default)  
 1 - encryption only  
 2 - decryption only  
 4 - signing only  
 8 - signature verification only  
16 - signing with message recovery only  
32 - signature verification with message recovery only  
64 - key wrapping only  

128 – key unwrapping only
256 – key derivation only

To specify more than one usage, add values together.

[url]
Verify one or more certificates. If a direct URL argument is provided, a TLS connection is attempted and the certificate presented by that server is evaluated according to standard SSL server policy; other certificates or policy options will be ignored in this case.

Options:

-c certFile

Certificate to verify, in DER or PEM format. Can be specified more than once; leaf certificate has to be specified first.

-r rootCertFile

Root certificate, in DER or PEM format. Can be specified more than once. If not specified, the system anchor certificates are used. If one root certificate is specified, and zero (non-root) certificates are specified, the root certificate is verified against itself.

-n name

Specify a name to be verified, e.g. the SSL host name for the ssl policy, or RFC822 email address for the smime policy. For backward compatibility, if the -n option is provided without an argument, it will be interpreted as equivalent to -N.

-N

Avoid searching any keychains.

-L

Use local certificates only. If an issuing CA certificate is missing, this option will avoid accessing the network to fetch it.

-l

Specifies that the leaf certificate is a CA cert. By default, a leaf certificate with a Basic Constraints extension with the CA bit set fails verification.

-e emailAddress

Specify email address for the smime policy. (This option is deprecated; use -n instead.)

-s sslHost

Specify SSL host name for the ssl policy. (This option is deprecated; use -n instead.)

-q

Quiet, no stdout or stderr.

-R revCheckOption

Specify a revocation checking option for this evaluation (ocsp, require, offline). Can be specified multiple times; e.g. to enable revocation checking via the OCSP method and require a positive response, use “-R ocsp -R require”.

id, available
ids can be listed by list-smartcards command.

-t certs|privKeys|identities|all

Display items of the specified type (Default:
all)

-e exportPath

Specify path to export certificates and public keys. If
exportPath is specified screen output is suppressed. This option cannot be combined with -t option.

The error can be in decimal or hex, e.g. 1234 or 0x1234. Multiple
errors can be separated by spaces.

ENVIRONMENT

MallocStackLogging

When using the
leaks
command or the
-l
option it’s probably a good idea to set this environment variable before
security
is started. Doing so will allow leaks to display symbolic backtraces.

FILES

~/Library/Preferences/com.apple.security.plist

Property list file containing the current user’s default keychain and keychain search list.

/Library/Preferences/com.apple.security.plist

Property list file containing the system default keychain and keychain search list. This is used by processes started at boot time, or those requesting to use the system search domain, such as system daemons.

/Library/Preferences/com.apple.security-common.plist

Property list file containing the common keychain search list, which is appended to every user’s search list and to the system search list.

HISTORY

security
was first introduced in Mac OS X version 10.3.

BUGS

security
still needs more commands before it can be considered complete.
In particular, it should someday supersede both the
certtool
and
systemkeychain
commands.
