I have often found bash to be difficult when it comes to floating point numbers. I have data with rows of tab delimited floating point numbers. I need to find the smallest number in each row that is not 0.0. Numbers can be negative and they do not come in any particular order for a given... (9 Replies)

I have the following code snippet in bash

It works well for most of the cases. However lets say diff is -0.17 and minm is -0.0017. In such a case the comparison seems to fail. Is the correct way to compare a mixture of positive and... (12 Replies)

crashinfo
CRASHINFO(8) BSD System Manager's Manual CRASHINFO(8) NAME
crashinfo -- analyze a core dump of the operating system SYNOPSIS
crashinfo [-d crashdir] [-n dumpnr] [-k kernel] [core] DESCRIPTION
The crashinfo utility analyzes a core dump saved by savecore(8). It generates a text file containing the analysis in the same directory as the core dump. For a given core dump file named vmcore.XX the generated text file will be named core.txt.XX. By default, crashinfo analyzes the most recent core dump in the core dump directory. A specific core dump may be specified via either the core or dumpnr arguments. Once crashinfo has located a core dump, it analyzes the core dump to determine the exact version of the kernel that generated the core. It then looks for a matching kernel file under each of the subdirectories in /boot. The location of the kernel file can also be explicitly provided via the kernel argument. Once crashinfo has located a core dump and kernel, it uses several utilities to analyze the core including dmesg(8), fstat(1), iostat(8), ipcs(1), kgdb(1), netstat(1), nfsstat(1), ps(1), pstat(8), and vmstat(8). The options are as follows: -d crashdir Specify an alternate core dump directory. The default crash dump directory is /var/crash. -n dumpnr Use the core dump saved in vmcore.dumpnr instead of the latest core in the core dump directory. -k kernel Specify an explicit kernel file. SEE ALSO
textdump(4), savecore(8) HISTORY
The crashinfo utility appeared in FreeBSD 6.4. BSD
