fg 200d

Background:Recently in the implementation of some long-time procedures, always accidentally forgot to enter the ' ', the end of the terminal is stuck there, it is depressedA new terminal was always opened in the past.Today, look at "Bird Brother's Linux private dishes", when the introduction of vim introduced a ctrl-z command can be the current program cut into the background, very useful! But how do you cut it back? Search, see below:-----------reprinted from: http://blog.chinaunix.net/uid-102

% overtime. Judging from my experience that this is a mathematical problem, let's analyze the key information in the topic description and see if there is any mystery. Small octopus can only be moved to 4 * x + 3 or 8 * x + 7, then we think F (x) =4 * x + 3, g (x) =8 * x + 7. The key part arrived, I stare two eyes for a long time, finally found1. F (g (x)) = g (f (x)) We can assume that the final movement of the small octopus is a string that can be expressed in

Question: Ctrl-z and ctrl-c difference? Reply: Ctrl-z and Ctrl-c are both interrupt orders, but their roles are different. Ctrl-c is the execution of a mandatory interrupt program, And the ctrl-z is to break the task, but this task is not over, he is still in the process he just maintained a suspended state, the user can use the FG/BG operation to continue the task of the foreground or the background, FG co

Oracle provides a new pseudo-column in 10g: Connect_by_isleaf, which allows you to determine whether the current record is a leaf node of a tree. Here is a description of how to implement the corresponding function in 9i. First, construct an example: Sql> CREATE TABLE t_tree (ID number PRIMARY KEY, father_id number, NAME VARCHAR2 (30)); Table has been created. Sql> INSERT into T_tree VALUES (1, 0, ' A '); 1 lines have been created. Sql> INSERT into T_tree VALUES (2, 1, ' BC '); 1 lines have be

It is equivalent to placing the current task in the background, using the FG command to recall the task.

Suppose you find it takes a long time to run a program on the front end, but you need to do other things, you can use CTRL-Z, terminate the program, and then you can see the system prompt: [1] + stopped/root/bin/rsync. Sh Then we can schedule the program to the background for execution: (the number following BG is the job number) # BG 1 [1] +/root/bin/rsync. Sh Run the jobs command to view running tasks: # Jobs [1] + running/root/bin/rsync. Sh If you want to call it back to the foreground, you

On the Linux bash shell single terminal interface, we often need to manage or complete multiple jobs at the same time, for example, execute compilation, implement data backup, and execute SQL queries and other tasks. All of the above work can be implemented in a bash, that is, in the same terminal window. The following describes how to switch and manage foreground and background jobs in Linux and how to manage jobs offline. 1. Definition of foreground and background jobsThe front and back-end jo

Question: Ctrl-z and ctrl-c difference?Reply:Ctrl-z and Ctrl-c are both interrupt commands, but their role is different.Ctrl-c is the execution of a forced interrupt program,And Ctrl-z is the task is interrupted, but this task does not end, he is still in the process he just maintain a suspended state, the user can use the FG/BG operation to continue the foreground or background tasks, FG command Restart th

Linux Job Management Before introducing job management, you must first know that job management is used in the bash environment. That is to say, "After logging on to the system to obtain the bash shell, you can manage multiple jobs at the same time on a single terminal interface ". In this way, we should know that when you manage jobsEach job is the current bash subroutineThat is, they are associated with each other. We cannot manage the bash of tty2 in the tty1 environment by job management.Dir

For example, I need to decompress Or compress another 70 GB object. I can't always open a terminal. If I keep on a terminal, if the transfer is half done, I need to cut off the power or cut off the network, you are finished, so we can put her on the terminal to run: @ #: nohup your shell command example: nohup tar-zxvf/var/www/html.tar.gz this command will generate a nohup log Example 2: Check whether the work in the background has been completed or transferred to the foreground for running: u

It is known that the forward order is abcdefg, and the middle order is cbedafg. First, 1st letters (a) In the first order are used to divide the middle order into two segments (cbed) (AFG) A As the root (cbed) as the left subtree (FG) right subtree Then, divide the parts following the forward order into (bcde) (FG) Parts by length) The problem is converted It is known that the first order is bcde, and the

, on the tty3 terminal, place vim in the background using ctrl + z and pause it. In the current tty, run the jobs command to view the background task list, as shown in: At this time, log on to the new tty and run the jobs command to check that no jobs are in the background: Export/WN0cmwmIzQzO3q/7L3dvPy1xLe9yr2jrL/blend/bI58/C19bR + fill = "brush: java;"> [1] + Stopped vim [1] indicates the number of the job, which is used when the job is placed on the foreground or when the background process
