It would be helpful to see a sample of your converted data and the code that is trying to accumulate it. If your converted data is whole integers, then expr should work - you don't need to do any conversion on the ascii string.
If you have decimal points, expr will not handle it. You can pipe your data into the following command, which will accumulate the first word on each line, and will allow decimal points.

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)
I am trying to get the ellapsed time in seconds in the body of the awk script. I use unix date to get the time. It works in BEGIN {} but not in the body {} of awk. Any ideas?
$ cat a

print x
}
{
"date +%s" | getline y
print y

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)
Hello all,
I got some time duration data like below and I want to compute the cumulative elapsed time. The data is in MM:SS.SS format. I got struck with logic on what to do when it changes from 59:59.ss to 00:00.ss.
59:59.4
59:59.6
59:59.9
00:00.1
00:00.4
00:00.6

script
SCRIPT(1) User Commands SCRIPT(1)NAME
script - make typescript of terminal session
SYNOPSIS
script [options] [file]
DESCRIPTION
script makes a typescript of everything displayed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves the dialogue in this file. If no filename is given, the dialogue is saved in the file type-
script.
OPTIONS -a, --append
Append the output to file or to typescript, retaining the prior contents.
-c, --command command
Run the command rather than an interactive shell. This makes it easy for a script to capture the output of a program that behaves
differently when its stdout is not a tty.
-e, --return
Return the exit code of the child process. Uses the same format as bash termination on signal termination exit code is 128+n.
-f, --flush
Flush output after each write. This is nice for telecooperation: one person does `mkfifo foo; script -f foo', and another can
supervise real-time what is being done using `cat foo'.
--force
Allow the default output destination, i.e. the typescript file, to be a hard or symbolic link. The command will follow a symbolic
link.
-q, --quiet
Be quiet (do not write start and done messages to standard output).
-t[file], --timing[=file]
Output timing data to standard error, or to file when given. This data contains two fields, separated by a space. The first field
indicates how much time elapsed since the previous output. The second field indicates how many characters were output this time.
This information can be used to replay typescripts with realistic typing and output delays.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
NOTES
The script ends when the forked shell exits (a control-D for the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
It is not recommended to run script in non-interactive shells. The inner shell of script is always interactive, and this could lead to
unexpected results. If you use script in the shell initialization file, you have to avoid entering an infinite loop. You can use for
example the .profile file, which is read by login shells only:
if test -t 0 ; then
script
exit
fi
You should also avoid use of script in command pipes, as script can read more input than you would expect.
ENVIRONMENT
The following environment variable is utilized by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed.
(Most shells set this variable automatically).
SEE ALSO csh(1) (for the history mechanism), scriptreplay(1)HISTORY
The script command appeared in 3.0BSD.
BUGS
script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
script is primarily designed for interactive terminal sessions. When stdin is not a terminal (for example: echo foo | script), then the
session can hang, because the interactive shell within the script session misses EOF and script has no clue when to close the session. See
the NOTES section for more information.
AVAILABILITY
The script command is part of the util-linux package and is available from Linux Kernel Archive <https://www.kernel.org/pub/linux/utils
/util-linux/>.
