NAME cpupower frequency-set – A small tool which allows to modify cpufreq settings. SYNTAX cpupower [ -c cpu ] frequency-set [options] DESCRIPTION cpupower frequency-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed" all the time. OPTIONS -d –min <FREQ> new minimum CPU frequency the governor may select. -u –max <FREQ> new…

NAME cpupower frequency-info – Utility to retrieve cpufreq kernel information SYNTAX cpupower [ -c cpulist ] frequency-info [options] DESCRIPTION A small tool which prints out cpufreq information helpful to developers and interested users. OPTIONS -e –debug Prints out debug information. -f –freq Get frequency the CPU currently runs at, according to the cpufreq core. -w…

NAME cpuid – Dump CPUID information for each CPU SYNOPSIS cpuid [options…] DESCRIPTION cpuid dumps detailed information about the CPU(s) gathered from the CPUID instruction, and also determines the exact model of CPU(s) from that information. It dumps all information available from the CPUID instruction. The exact collection of information available varies between manufacturers and…

NAME cpufreq-set – A small tool which allows to modify cpufreq settings. SYNTAX cpufreq-set [options] DESCRIPTION cpufreq-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed" all the time. OPTIONS -c –cpu <CPU> number of CPU where cpufreq settings shall be modified. -d –min <FREQ> new minimum CPU frequency the governor may…

NAME cpufreq-info – Utility to retrieve cpufreq kernel information SYNTAX cpufreq-info [options] DESCRIPTION A small tool which prints out cpufreq information helpful to developers and interested users. OPTIONS -c –cpu <CPU>  <CPU> number which information shall be determined about. -e –debug Prints out debug information. -f –freq Get frequency the CPU currently runs at, according to…

NAME cpufreq-aperf – Calculates the average frequency over a time period SYNTAX cpufreq-aperf [options] DESCRIPTION On latest processors exist two MSR registers refered to as:   – MPERF increasing with maxium (P0) frequency in C0   – APERF increasing with current/actual frequency in C0 From this information the average frequency over a time period can be calculated and this…

NAME cpttext – print text coloured by a GMT colour palette table (cpt) file. SYNOPSIS cpttext [-h] [-H] [-t text] [-v] [-V] [file] DESCRIPTION The cpttext program prints text in the colours specified by the GMT(1) colour palette table (cpt) file. Currently only HTML output is supported. The program will read the cpt file from stdin…

NAME cptsvg – convert GMT colour palette tables (cpt) to SVG gradients. SYNOPSIS cptsvg [-g geometry] [-h] [-o file] [-p] [-v] [-V] [file] DESCRIPTION The cptsvg utility converts the colour palette table (cpt) files used by GMT(1) to the gradients in the Scalar Vector Graphics (SVG) format. The program will read from stdin if a file is…

NAME cptinfo – print summary information on GMT colour palette table (cpt) files. SYNOPSIS cptinfo [-c] [-h] [-o file] [-p] [-v] [-V] [file] DESCRIPTION The cptinfo utility prints summary information on the colour palette table (cpt) file which is its input. The program will read from stdin if a file is not specified as the final…

NAME cpthsv – modify hue, saturation and colour value of GMT colour palette tables. SYNOPSIS cpthsv -T transform [-h] [-o file] [-v] [-V] [file] DESCRIPTION The cpthsv utility reads the RGB colour palette in the input, converts its colours to the HSV colour-space, modifies these values in some simple ways, then converts back to RGB colour space…

NAME cptcss – create CSS fragment for colouring HTML tables. SYNOPSIS cptcss [-h] [-f format] [-v] [-V] [file] DESCRIPTION The cptcss utility prints a fragment of CSS which can be used to colour the cells of an HTML table, the colours specified by a colour palette table (cpt) file. The cpt file to use is specified…

NAME cptcont – create a continuous GMT colour palette table (cpt) file based on the colours of a non-continuous cpt file. SYNOPSIS cptcont [-h] [-m] [-o file] [-p percent] [-v] [-V] [file] DESCRIPTION The cptcont program converts a (possibly) discontinuous colour palette in the input to a continuous palette in the output. This is achieved by replacing…
