Uptime Uptime shows how long the system has been running. You can see the same information by running uptime:

An unquoted backslash followed by a newline are discarded and cause the shell to wait for more input. The backslash and newline are discarded before the shell tokenizes the string, so long lines can be split anywhere outside of single quotes, even in the middle of command names and variable names.

In the shell grammar, lists contain sublists, which contain pipelines, which contain simple commands.


Subshells and grouping can be used to put a list in a pipeline. Subshells and groups can have newlines, but the shell defers execution until the end of the subshell or group is reached. The section on execution control describes structures which do not fit into the simple grammar and execution model outlined here.

The shell will not execute any of the control structures until the end keyword is reached. As a result, the control structure can contain multiple statements separated by newlines. Execution control structures cannot be put into pipelines. The shell looks successively for a user-defined function, built-in function, and external command in the search path matching the word.

The first one found is run. If no matching function or external command is found the shell emits a warning and sets its status variable to a nonzero value.

It does not return the status value to its caller unless it has reached the end of its input, however.In modern Unixes ps is implemented using /proc pseudo filesystem. That means it reads data from it and does not requires additional privileges.

List Of Objects:

See also top command which is a simple monitoring tool for running process similar to ps but able to work in interactive mode. Suppose I have a process which spawns exactly one child process.

Now when the parent process exits for whatever reason (normally or abnormally, by kill, ^C, assert failure or anything else) I want. About. Based on this, I have written a small program for the STM32F4 Discovery that uses the USB-CDC class to show up as an virtual serial port.I’m using the USB stack provided by ST, however, there is also another project that uses libopencm3 that can be found here.I have routed the write system call to use this port, so the stdio printf function will .

Description Conversion is performed between long and radix characters. The l64a routine transforms up to 32 bits of input value starting from least significant bits to the most significant bits.

The input value is split up into a maximum of 5 groups of 6 bits and possibly one group of 2 bits (bits 31 and 30).
