This article mainly explains "the usage of more command in linux". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn the usage of the more command in linux.

1. Command format:

More [- dlfpcsu] [- num] [+ / pattern] [+ linenum] [file...]

2. Command function:

The more command is the same as cat's function is to view the contents of the file, but the difference is that more can view the contents of the file by page, but also supports direct jump line and other functions.

3. Command parameters:

+ n starts with line n.

-n defines the screen size as n lines

+ / pattern searches for the string (pattern) before each file is displayed, and then displays it after the first two lines of the string

-c clear the screen from the top and display

-d prompt "Press space to continue,'q' to quit (press Spacebar to continue, press Q key to exit)" to disable the ringing function

-l ignores Ctrl+l (page feed) characters

-p page the file by clearing the window instead of scrolling, similar to the-c option

-s displays consecutive blank lines as one line

-u remove the underline from the contents of the file

4. Common operation commands:

Enter goes down n lines and needs to be defined. The default is 1 line

Ctrl+F scrolls down one screen

The space bar scrolls down one screen

Ctrl+B returns to the previous screen

= output the line number of the current line

: F output file name and line number of the current line

V calls the vi editor

! Command invokes Shell and executes the command

Q exit more

5. Command example:

Example 1: displays the contents of the file starting from line 3

Command:

More + 3 log2012.log

Output:

The code is as follows:

[root@localhost test] # cat log2012.log

2012-02

2012-03

2012-04-day1

2012-04-day2

2012-04-day3

= [root@localhost test] # more + 3 log2012.log

2012-03

2012-04-day1

2012-04-day2

2012-04-day3

= [root@localhost test] #

Example 2: find the first line where the "day3" string appears in the file, and display the output from the first two lines there

Command:

Output:

The code is as follows:

[root@localhost test] # more + / day3 log2012.log

= [root@localhost test] #

Example 3: set the number of rows displayed per screen

The bottom shows the proportion of the content displayed on this screen to the total number of lines of the file. Pressing Ctrl+F or the Spacebar will display 5 items on the next screen, and the percentage will change accordingly.

Example 4: list the files under a directory, because there are too many contents, we should learn to use more to page display. This has to be combined with plumbing |

Command:

Ls-l | more-5

Output:

The code is as follows:

[root@localhost test] # ls-l | more-5
