I am writting a script in the ksh shell and am trying to find a way to report the total execution time of the script without requiring the user to specify the time function when executing the script.
Does anyone have any examples they have used. I have been setting up two date variables (one at... (9 Replies)

I have just written a Csh script and i want to find out how long does the script take to complete executing. Is there any codes which i can put into my script to capture its run time ? (9 Replies)
Hi,
I have a simple question. How can I get the execution time of a script and maybe put it in a variable?
Another question. How can I get only time and not date and put it in a variable? I tried something with "date" command but with no success...
If someone could help me... (8 Replies)
Hi All,
Can we get to know the start time and end time of execution of a script? (This script doesn't write any logs.) I mean, is there any built in process logs to track these records? (2 Replies)
Hello,
I'm running a bash script and I'd like to get more accurate a runtime information then now.
So far I've been using this method:
STARTM=`date -u "+%s"`
.........
*script function....
.........
STOPM=`date -u "+%s"`
RUNTIMEM=`expr $STOPM - $STARTM`
if (($RUNTIMEM>59)); then... (6 Replies)

Hi,
I have a HP-UX server were I need to list all the files in the entire file system, their directory path, last modified date, owner and group. I do not need to search the file contents.

Hello Guys,
I would like to know is there a way to take the script execution time
For e.g i am having a script.sh i need to write inside he script.sh like

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
