Unix command help version 2.0
Having trouble doing the following things, I know it has something to do with using metacharacters but I'm not able to get it working correctly.
I need a command to get a long directory listing of all the files that have:
exactly two characters following the letters zot.
all files that have 0 or more characters after the leltters zot
and then I need to use the history command to re-execute the command that listed all the files with an even last digit in the name.
thanks for anyone who can help
RE: yes it is homework, out of 45 questions I'm asking on how to do 1 command, and not asking for the answer I'm asking for any kind of help.....

APPLY(1) BSD General Commands Manual APPLY(1)
NAME
apply -- apply a command to a set of arguments
SYNOPSIS
apply [-a c] [-d] [-#] command argument ...
DESCRIPTION
The apply utility runs the named command on each argument argument in turn.
Character sequences of the form ``%d'' in command, where 'd' is a digit from 1 to 9, are replaced by the d'th following unused argument. In
this case, the largest digit number of arguments are discarded for each execution of command.
The options are as follows:
-# Normally arguments are taken singly; the optional number -# specifies the number of arguments to be passed to command. If the number
is zero, command is run, without arguments, once for each argument.
If any sequences of ``%d'' occur in command, the -# option is ignored.
-a c The use of the character '%' as a magic character may be changed with the -a option.
-d Display the commands that would have been executed, but do not actually execute them.
ENVIRONMENT
The following environment variable affects the execution of apply:
SHELL Pathname of shell to use. If this variable is not defined, the Bourne shell is used.
EXAMPLES
apply echo a*
is similar to ls(1);
apply -2 cmp a1 b1 a2 b2 a3 b3
compares the `a' files to the `b' files;
apply -0 who 1 2 3 4 5
runs who(1) 5 times; and
apply 'ln %1 /usr/joe' *
links all files in the current directory to the directory /usr/joe.
FILES
/bin/sh default shell
AUTHORS
Rob Pike
BUGS
Shell metacharacters in command may have bizarre effects; it is best to enclose complicated commands in single quotes ('').
HISTORY
The apply command appeared in 4.2BSD.
BSD
April 4, 1994 BSD
