Oh yes, that's right, neither bash nor POSIX shell understands floating point (for that you need ksh93 or zsh), so that is another external program.. Try:

perhaps full perl would be best here...

Here is my code. What it does is it reads an input file (input.txt which contains roughly 2,000 search phrases) and searches a directory for files that contains the search phrase. The directory contains roughly 1900 files and 84 subdirectories. The output is a file (output.txt) that shows only the... (23 Replies)
Hello,
I'm wondering if there is a quicker way of doing this.
Here is my mv script.

Hi guys,
I feel a bit comfortable now doing bash scripting but I am worried that the way I do it is not optimized and I can do much better as to how I code.
e.g.
I have a whole line in a file from which I want to extract some values.
Right now what I am doing is :

how can i optimize the following:
TOTALRESULT="total1=4
total2=9
total3=89
TMEMORY=1999"
TOTAL1=$(echo "${TOTALRESULT}" | egrep "total1=" | awk -F"=" '{print $NF}')
TOTAL2=$(echo "${TOTALRESULT}" | egrep "total2=" | awk -F"=" '{print $NF}')

datetime - convert between TAI labels and seconds
SYNTAX
#include <datetime.h>
void datetime_tai(&dt,t);
datetime_sec datetime_untai(&dt);
struct datetime dt;
datetime_sec t;
DESCRIPTION
International Atomic Time, TAI, is the fundamental unit for time measurements. TAI has one label for every second of real time, without
complications such as leap seconds.
A struct datetime variable, such as dt, stores a TAI label. dt.year is the year number minus 1900; dt.mon is the month number, from 0
(January) through 11 (December); dt.mday is the day of the month, from 1 through 31; dt.hour is the hour, from 0 through 23; dt.min is the
minute, from 0 through 59; dt.sec is the second, from 0 through 59; dt.wday is the day of the week, from 0 (Sunday) through 6 (Saturday);
dt.yday is the day of the year, from 0 through 365.
The datetime library supports more convenient TAI manipulation with the datetime_sec type. A datetime_sec value, such as t, is an integer
referring to the tth second after the beginning of 1970 TAI. The first second of 1970 TAI was 0; the next second was 1; the last second of
1969 TAI was -1. The difference between two datetime_sec values is a number of real-time seconds.
datetime_tai converts a datetime_sec to a TAI label.
datetime_untai reads a TAI label (specifically dt.year, dt.mon, dt.mday, dt.hour, dt.min, and dt.sec) and returns a datetime_sec.
