Hi,
I have a log file that gets updated every second. Currently the size has grown to 20+ GB. I need to have a command/script, that will try to get the actual size of the file and will remove 50% of the data that are in the log file. I don't mind removing the data as the size has grown to huge... (8 Replies)

I would like to write a shell script that calculated the time difference bettween the log entries. If the time difference is higher as 200 sec. print the complette lines out.
My Problem is, i am unable to jump in the next line and calculate the time difference.
Thank you for your Help.

However when I try to get the information in Perl via a piped open, it waits till the end to give me anything... my code:

ISGREATER(3) BSD Library Functions Manual ISGREATER(3)NAME
isgreater, isgreaterequal, isless, islessequal, islessgreater, isunordered -- compare two floating-point numbers
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <math.h>
int
isgreater(real-floating x, real-floating y);
int
isgreaterequal(real-floating x, real-floating y);
int
isless(real-floating x, real-floating y);
int
islessequal(real-floating x, real-floating y);
int
islessgreater(real-floating x, real-floating y);
int
isunordered(real-floating x, real-floating y);
DESCRIPTION
Each of the macros isgreater(), isgreaterequal(), isless(), islessequal(), and islessgreater() takes arguments x and y and returns a non-zero
value if and only if its nominal relation on x and y is true. These macros always return zero if either argument is not a number (NaN), but
unlike the corresponding C operators, they never raise a floating point exception.
The isunordered() macro takes arguments x and y, returning non-zero if either x or y is NaN. For any pair of floating-point values, one of
the relationships (less, greater, equal, unordered) holds.
SEE ALSO fpclassify(3), math(3), signbit(3)STANDARDS
The isgreater(), isgreaterequal(), isless(), islessequal(), islessgreater(), and isunordered() macros conform to ISO/IEC 9899:1999
(``ISO C99'').
