It is also a great way to obtain the user ID (login name) for a person if you only know their name. You can user finger to locate people using either their first or last name, or directly by using their user id./home/hayhurst- finger camilleLogin name: hayhurst In real life: Camille A.

This displays help in 2 ways. 1) you can askfor the help page(S) for a specific command to be displayed. As in:/home/hayhurst- man lsReformatting page. Wait... doneNAME ls - list contents of directorySYNOPSIS /usr/bin/ls [ -aAbcCdfFgilLmnopqrRstux1 ] /usr/xpg4/bin/ls [ -aAbcCdfFgilLmnopqrRstux1 ] DESCRIPTION For each file that is a directory, ls lists the contents of the directory; for each file that is an ordinary file, ls repeats its name and any other information requested. The output is sorted alphabetically by default. When no argument is given, the current directory is listed. When several arguments are given, the arguments are first sorted appropriately, but file arguments appear before directories and their contents. There are three major listing formats. The default format for output directed to a terminal is multi-column with entries sorted down the columns. The -1 option allows single column output and -m enables stream output format. In order to determine output formats for the -C, -x, and -m options, ls uses an environment variable, COLUMNS, to determine the number of character positions available on one output line. If this variable is not set, the terminfo(4) database is used to determine the number of columns, based on the environment variable TERM. If this information cannot be obtained, 80 columns are assumed.There was too much information to copy sotry this on your own.You can also use man with the keyword option (-k) to lood for entries which reference directories./home/hayhurst- man -k directory/home/hayhurst/man/windex: No such file or directoryalphasort
