There's probably more elegant ways depending on what your string actually comes from. You could probably extract it - or several - from a file and whittle it down to TDMN, etc in one step.
Hi,
Suppose I have the following text in a file.
ORA-00942: table or view does not exist
ORA-01555: snapshot too old: rollback segment number string with name "string"
too small
Is there any way I can list all the text that starts only with 'ORA-'?
Or there any grep command that can... (7 Replies)
Hi,
I have a file with rows of text like so :

Hello
Could you help with small script:
How to split string X1 into 3 string
String X1 can have 1 or many strings

i have something like this...
echo "teCertificateId" | awk -F'Id' '{ print $1 }' | awk -F'te' '{ print $2 }'
Certifica
the awk should remove 'te' only if it is present at the start of the string.. anywhere else it should ignore it.
expected output is

cpupower-set
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
