Thanks R.Singh.
This code looks to be working on my first try. Input file is just what i've mentioned in my first question post. In the input file the above mentioned pattern repeats with different SName and ESys values. I'm trying to understand this code; VAL=$0. will this hold SName values?
Hi all, I need to category the processes in my system with awk. And for now, there are several command with similar name, so i have to match more than one pattern to pick it out. for instance:
binrundb
the string1, 2 & 3 may contain word, number, blank or "/". The "bin" should be ahead "rundb"... (5 Replies)
Hello All,
I am here again scratching my head on pattern selection with special characters.
I have a large file having around 200 entries and i have to select a single line based on a pattern.
I am able to do that:
Code:
cat mytest.txt | awk -F: '/myregex/ { print $2}'

Hi,
I have a problem where I need to make this input:

Hi,
I have a log file which has sessionids in it, each block in the log starts with a date entry, a block may be a single line or multiple lines. I need to sed (or awk) out the lines/blocks with that start with a date and include the session id.
The files are large at several Gb.

Dear Unix Forums,
I am hoping you can help me with a pattern matching problem.
What am I trying to do?
I want to replace multiple lines of a text file (that match a multi-line pattern) with a single line of text. These patterns can span several lines and do not always have the same number of... (10 Replies)

Hi all. So, first of all my apologies for the noob question. I've searched around for a way to make use of bash arrays to perform what I need, but I'm struggling to understand which method would be better.
So, I'm looking to get a bit more comfortable with scripting, hoping to use... (1 Reply)

CPUPOWER-SET(1) cpupower Manual CPUPOWER-SET(1)NAME
cpupower-set - Set processor power related kernel or hardware configurations
SYNOPSIS
cpupower set [ -b VAL ] [ -s VAL ] [ -m VAL ]
DESCRIPTION
cpupower set sets kernel configurations or directly accesses hardware registers affecting processor power saving policies.
Some options are platform wide, some affect single cores. By default values are applied on all cores. How to modify single core configura-
tions is described in the cpupower(1) manpage in the --cpu option section. Whether an option affects the whole system or can be applied to
individual cores is described in the Options sections.
Use cpupower info to read out current settings and whether they are supported on the system at all.
Options--perf-bias, -b
Sets a register on supported Intel processore which allows software to convey its policy for the relative importance of performance
versus energy savings to the processor.
The range of valid numbers is 0-15, where 0 is maximum performance and 15 is maximum energy efficiency.
The processor uses this information in model-specific ways when it must select trade-offs between performance and energy efficiency.
This policy hint does not supersede Processor Performance states (P-states) or CPU Idle power states (C-states), but allows software to
have influence where it would otherwise be unable to express a preference.
For example, this setting may tell the hardware how aggressively or conservatively to control frequency in the "turbo range" above the
explicitly OS-controlled P-state frequency range. It may also tell the hardware how aggressively it should enter the OS requested C-
states.
This option can be applied to individual cores only via the --cpu option, cpupower(1).
Setting the performance bias value on one CPU can modify the setting on related CPUs as well (for example all CPUs on one socket),
because of hardware restrictions. Use cpupower -c all info -b to verify.
This options needs the msr kernel driver (CONFIG_X86_MSR) loaded.
--sched-mc, -m [ VAL ]
--sched-smt, -s [ VAL ]
--sched-mc utilizes cores in one processor package/socket first before processes are scheduled to other processor packages/sockets.
--sched-smt utilizes thread siblings of one processor core first before processes are scheduled to other cores.
The impact on power consumption and performance (positiv or negativ) heavily depends on processor support for deep sleep states, fre-
quency scaling and frequency boost modes and their dependencies between other thread siblings and processor cores.
Taken over from kernel documentation:
Adjust the kernel's multi-core scheduler support.
Possible values are:
0 - No power saving load balance (default value)
1 - Fill one thread/core/package first for long running threads
2 - Also bias task wakeups to semi-idle cpu package for power savings
