Top Forums Shell Programming and Scripting How can I add 4 lines together and then read the next 4 lines? Post 302261921 by mr_andrew on Wednesday 26th of November 2008 03:19:04 AM

Thanks for your effort now it works.

# awk 'END {
> if (t)
> print e, "Total:", t
> }

if (t)
> /\.exe/ {
> if (t)
> print e, "Total:", t
> t = 0
> e = $0 }
/Total/ { t += $NF }
' nisse_081121_11.log
> }
> /Total/ { t += $NF }
> ' nisse_081121_11.log
081125_08:38 14315 2.39 798928 198257 SOM.exe Total: 56098
081125_09:38 14315 2.32 798928 198257 SOM.exe Total: 57220
#

If I want to search for another word, would it just do to change Total?

/Total/ { t += $NF }

And if it is not that clean as it is now with the numbers. If it was text after it. I.e

Total houses = 32245 houses

Would it still work?

SYSINFO(2)						     Linux Programmer's Manual							SYSINFO(2)

NAME
sysinfo - returns information on overall system statistics SYNOPSIS
#include <sys/sysinfo.h> int sysinfo(struct sysinfo *info); DESCRIPTION
Until Linux 2.3.16, sysinfo() used to return information in the following structure: struct sysinfo { long uptime; /* Seconds since boot */ unsigned long loads[3]; /* 1, 5, and 15 minute load averages */ unsigned long totalram; /* Total usable main memory size */ unsigned long freeram; /* Available memory size */ unsigned long sharedram; /* Amount of shared memory */ unsigned long bufferram; /* Memory used by buffers */ unsigned long totalswap; /* Total swap space size */ unsigned long freeswap; /* swap space still available */ unsigned short procs; /* Number of current processes */ char _f[22]; /* Pads structure to 64 bytes */ }; and the sizes were given in bytes. Since Linux 2.3.23 (i386), 2.3.48 (all architectures) the structure is: struct sysinfo { long uptime; /* Seconds since boot */ unsigned long loads[3]; /* 1, 5, and 15 minute load averages */ unsigned long totalram; /* Total usable main memory size */ unsigned long freeram; /* Available memory size */ unsigned long sharedram; /* Amount of shared memory */ unsigned long bufferram; /* Memory used by buffers */ unsigned long totalswap; /* Total swap space size */ unsigned long freeswap; /* swap space still available */ unsigned short procs; /* Number of current processes */ unsigned long totalhigh; /* Total high memory size */ unsigned long freehigh; /* Available high memory size */ unsigned int mem_unit; /* Memory unit size in bytes */ char _f[20-2*sizeof(long)-sizeof(int)]; /* Padding for libc5 */ }; and the sizes are given as multiples of mem_unit bytes. sysinfo() provides a simple way of getting overall system statistics. This is more portable than reading /dev/kmem. RETURN VALUE
On success, zero is returned. On error, -1 is returned, and errno is set appropriately. ERRORS
EFAULT pointer to struct sysinfo is invalid CONFORMING TO
This function is Linux-specific, and should not be used in programs intended to be portable. The Linux kernel has a sysinfo() system call since 0.98.pl6. Linux libc contains a sysinfo() routine since 5.3.5, and glibc has one since 1.90. SEE ALSO
