It is running now. I used my installed copy of ubuntu to use the time command. However I get 3 different lines of output:
I do believe my assignment instructions say to sum the first two numbers but my output is different than the example in the first post. I should sum the user and sys values. So what is the number in the "real" field for? Should I ignore it for this assignment?

Reason: Code tags
I wondered if someone could point out the differences between the time commmand and usr/bin/time and the accuracy one might have over another.
Also, is there a website or two a person could maybe link for me to describe the differences?
Thank you for your time. (2 Replies)

Hi,
Using ksh, I have set up aliases (which work fine) in my user's .profile like this:
alias ll = 'ls -lrt'
alias cls = 'clear'
How do I call these same aliases so that they will work after issuing this: ? su - user
I do not want to add aliases to the su shell's .profile or .kshrc. (7 Replies)

mktemp
mktemp(3C) Standard C Library Functions mktemp(3C)NAME
mktemp - make a unique file name from a template
SYNOPSIS
#include <stdlib.h>
char *mktemp(char *template);
DESCRIPTION
The mktemp() function replaces the contents of the string pointed to by template with a unique file name, and returns template. The string
in template should look like a file name with six trailing 'X's; mktemp() will replace the 'X's with a character string that can be used to
create a unique file name. Only 26 unique file names per thread can be created for each unique template.
RETURN VALUES
The mktemp() function returns the pointer template. If a unique name cannot be created, template points to a null string.
ERRORS
No errors are defined.
EXAMPLES
Example 1: Generate a filename.
The following example replaces the contents of the "template" string with a 10-character filename beginning with the characters "file" and
returns a pointer to the "template" string that contains the new filename.
#include <stdlib.h>
...
char *template = "/tmp/fileXXXXXX";
char *ptr;
ptr = mktemp(template);
USAGE
Between the time a pathname is created and the file opened, it is possible for some other process to create a file with the same name. The
mkstemp(3C) function avoids this problem and is preferred over this function.
