does the system command allow to capture the output of it? Eventually I would like to subtract the values: y-x in the script. This script, obviously, does not work:

I'm using the Bourne shell and trying to write a script that will add all the time that any particular user has been on the network for.
I've used last-h | grep "username" | cut -c 58-62 to get the times.
Then I wrote a script that takes the time and converts it into just minutes.
Now I... (1 Reply)
I'm looking for the cleanest way to calculate the time elapsed between two times in KSH. In minutes or in hours and minutes if it has been longer than 59 minutes.
Here are some random examples:
Example result: 25 Minutes

Example result: 1 Hour and 25 Minutes
Example time format:

Hi there,
How to calculate the elapsed time in minutes for a particular job run under unix.
I tried the following
$ ps -efo user,pid,etime,comm,args | grep myscript | grep -v grep | awk -F" " '{print $3}'
OUTPUT:
01:02:49
I need to get this output in minutes.
Can someone help me... (1 Reply)
Hi All,
I have 2 variables like SDATE and EDATE.
Now for example i ll give you values for the above 2 variables.
SDATE=11/08/09 11:22
EDATE=11/09/09 22:33
the values of the above variables are represented like this>>>>>> mm/dd/yy hh:mm Now I want to evaluate total time elapsed... (3 Replies)
Hi
I want to know if there is anyway I can find out how long it has been since I started my script or total time it has been since my script is executing.
Idea here is I want to check if my script is taking more than 30minutes to execute I want to kill that process.
Thanks in advance. (1 Reply)
I'm extracting two time & date values from a log file, and I need a way to calculate the elapsed time between the two. The values are in this format:
Feb 12 10:53:15
Feb 12 10:59:57
The difference is 6 minutes and 42 seconds
Does anyone know if there is a way to do this? I've seen lots of... (4 Replies)

getline
GETDELIM(3) BSD Library Functions Manual GETDELIM(3)NAME
getdelim, getline -- read a delimited record from a stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
ssize_t
getdelim(char ** restrict lineptr, size_t * restrict n, int delimiter, FILE * restrict stream);
ssize_t
getline(char ** restrict lineptr, size_t * restrict n, FILE * restrict stream);
DESCRIPTION
The getdelim() function reads from the stream until it encounters a character matching delimiter, storing the input in *lineptr. The buffer
is NUL-terminated and includes the delimiter. The delimiter character must be representable as an unsigned char.
If *n is non-zero, then *lineptr must be pre-allocated to at least *n bytes. The buffer should be allocated dynamically; it must be possible
to free(3) *lineptr. getdelim() ensures that *lineptr is large enough to hold the input, updating *n to reflect the new size.
The getline() function is equivalent to getdelim() with delimiter set to the newline character.
RETURN VALUES
The getdelim() and getline() functions return the number of characters read, including the delimiter. If no characters were read and the
stream is at end-of-file, the functions return -1. If an error occurs, the functions return -1 and the global variable errno is set to indi-
cate the error.
The functions do not distinguish between end-of-file and error, and callers must use feof(3) and ferror(3) to determine which occurred.
EXAMPLES
The following code fragment reads lines from a file and writes them to standard output.
char *line = NULL;
size_t linesize = 0;
ssize_t linelen;
while ((linelen = getline(&line, &linesize, fp)) != -1)
fwrite(line, linelen, 1, stdout);
if (ferror(fp))
perror("getline");
ERRORS
[EINVAL] lineptr or n is a NULL pointer.
[EOVERFLOW] More than SSIZE_MAX characters were read without encountering the delimiter.
The getdelim() and getline() functions may also fail and set errno for any of the errors specified in the routines fflush(3), malloc(3),
read(2), stat(2), or realloc(3).
SEE ALSO ferror(3), fgets(3), fopen(3)STANDARDS
The getdelim() and getline() functions conform to IEEE Std 1003.1-2008 (``POSIX.1'').
