The userdel command modifies the system account files, deleting all entries that refer to loginname. The named user must exist. Question: Q: Windows 'Run' Command on a Mac Is there a Mac equivalent to the Windows 'Run' option (in the Start Menu)?

Name
userdel - delete a user account and related files
Synopsis
userdel [options] LOGIN
Description
The userdel command modifies the system account files, deleting all entries that refer to the user name LOGIN. The named user mustexist.
Options
The options which apply to the userdel command are:
-f, --force
This option forces the removal of the user account, even if the user is still logged in. It also forces userdel to remove the user's home directoryand mail spool, even if another user uses the same home directory or if the mail spool is not owned by the specified user. If USERGROUPS_ENAB is definedto
yes in /etc/login.defs and if a group exists with the same name as the deleted user, then this group will be removed, even if it is still the primarygroup of another user.Note: This option is dangerous and may leave your system in an inconsistent state.
The mail spool is defined by the MAIL_DIR variable in the login.defs file.
Userdel User Does Not Exist
Configuration
The following configuration variables in /etc/login.defs change the behavior of this tool:
MAIL_DIR (string)
If MAIL_CHECK_ENAB is set to yes, they are also used to define the MAIL environment variable.
MAX_MEMBERS_PER_GROUP (number)
Maximum members per group entry. When the maximum is reached, a new group entry (line) is started in /etc/group (with the same name, same password, and sameGID).The default value is 0, meaning that there are no limits in the number of members in a group.
This feature (split group) permits to limit the length of lines in the group file. This is useful to make sure that lines for NIS groups are not larger than1024 characters.
If you need to enforce such limit, you can use 25.
Note: split groups may not be supported by all tools (even in the Shadow toolsuite). You should not use this variable unless you really need it.
The return code of the script is not taken into account.
Here is an example script, which removes the user's cron, at and print jobs:
echo 'Usage: $0 username'exit 1
fi# Remove cron jobs.
crontab -r -u $1
# Remove at jobs.
# Note that it will remove any jobs owned by the same UID,
# even if it was shared by a different username.
AT_SPOOL_DIR=/var/spool/cron/atjobs
find $AT_SPOOL_DIR -name '[^.]*' -type f -user $1 -delete ;
# Remove print jobs.
lprm $1
# All done.
exit 0
If set to yes, userdel will remove the user's group if it contains no more members, and useradd will create by default a group with thename of the user.

Caveats
userdel will not allow you to remove an account if there are running processes which belong to this account. In that case, you may have to kill thoseprocesses or lock the user's password or account and remove the account later. The -f option can force the deletion of this account.
You should manually check all file systems to ensure that no files remain owned by this user.
You may not remove any NIS attributes on a NIS client. This must be performed on the NIS server.
If USERGROUPS_ENAB is defined to yes in /etc/login.defs, userdel will delete the group with the same name as the user. To avoidinconsistencies in the passwd and group databases, userdel will check that this group is not used as a primary group for another user, and will justwarn without deleting the group otherwise. The -f option can force the deletion of this group.

This Cheat Sheet of timesaving keyboard shortcuts, mouse and trackpad actions, Mac-related websites, and definitions can help you get the most from your Mac right away.
Using Mac Special Feature Keys
Newer Macs feature keyboards with a row of dedicated special feature keys marked with descriptive icons that also double as function (Fn) keys. For instance, the fifth key from the left is the one you press to open Launchpad, which displays all the applications on your Mac. Some special feature keys evoke a second special feature when you hold down the Fn key and then press the special feature key.
From the Apple menu, choose System Preferences and then click the Keyboard icon to find all the default key command shortcuts (under the Shortcuts tab), turn on those you want to use, and then edit the key combinations to something easier for you.
Here are five Mac special feature keys you can press to help you work with and switch between multiple Mac application windows you’re running at the same time.

When writing, you may need to use a symbol or a letter with a diacritical mark, such as an accent (à) or a tilde (ñ).

Type the number, and the variation appears in your document. For example, hold down A and then press 1 to type à. It works for uppercase letters as well.
These variations appear when you use the U.S. English keyboard. If you add a keyboard for another language, you may see more or different variations. To add a keyboard, go to the Apple menu and choose System Preferences; then click the Keyboard icon. Click the Input Source tab and then click the add button (+) at the bottom left. Select the language you want, and then click the Add button. Select the Show Input Menu in Menu Bar check box.
