|
|
|
|
|
This module allows you to use line numbers to specify patterns or |
12
|
|
|
|
|
|
|
regions which can be used in B options. |

|
Simply, next command will show 200th line with before/after 10 lines |
19
|
|
|
|
|
|
|
of the file: |
20
|
|
|
|
|
|
|
|
21
|
|
|
|
|
|
|
greple -Mline -L 200 -C10 file |
22
|
|
|
|
|
|
|
|
23
|
|
|
|
|
|
|
If you don't like lines displayed with color, use B<--nocolor> option |
24
|
|
|
|
|
|
|
or set colormap to something do nothing like B<--cm=N>. |
25
|
|
|
|
|
|
|
|
26
|
|
|
|
|
|
|
Multiple lines can be specified by joining with comma: |
27
|
|
|
|
|
|
|
|
28
|
|
|
|
|
|
|
greple -Mline -L 10,20,30 |
29
|
|
|
|
|
|
|
|
30
|
|
|
|
|
|
|
It is ok to use B<-L> option multiple times, like: |
31
|
|
|
|
|
|
|
|
32
|
|
|
|
|
|
|
greple -Mline -L 10 -L 20 -L 30 |
33
|
|
|
|
|
|
|
|
34
|
|
|
|
|
|
|
But this command produce nothing, because each line definitions are |
35
|
|
|
|
|
|
|
taken as a different pattern, and B prints lines only when all |
36
|
|
|
|
|
|
|
patterns matched. You can relax the condition by C<--need 1> option |
37
|
|
|
|
|
|
|
in such case, then you will get expected result. Next example will |
38
|
|
|
|
|
|
|
display 10th, 20th and 30th lines in different colors. |
39
|
|
|
|
|
|
|
|
40
|
|
|
|
|
|
|
greple -Mline -L 10 -L 20 -L 30 --need 1 |
41
|
|
|
|
|
|
|
|
42
|
|
|
|
|
|
|
Range can be specified by colon: |
43
|
|
|
|
|
|
|
|
44
|
|
|
|
|
|
|
greple -Mline -L 10:20 |
45
|
|
|
|
|
|
|
|
46
|
|
|
|
|
|
|
You can also specify the step with range. Next command will print |
47
|
|
|
|
|
|
|
all even lines from line 10 to 20: |
48
|
|
|
|
|
|
|
|
49
|
|
|
|
|
|
|
greple -Mline -L 10:20:2 |
50
|
|
|
|
|
|
|
|
51
|
|
|
|
|
|
|
Any of them can be omitted. Next commands print all, odd and even |
52
|
|
|
|
|
|
|
lines. |
53
|
|
|
|
|
|
|
|
54
|
|
|
|
|
|
|
greple -Mline -L :: # all lines |
55
|
|
|
|
|
|
|
greple -Mline -L ::2 # odd lines |
56
|
|
|
|
|
|
|
greple -Mline -L 2::2 # even lines |
57
|
|
|
|
|
|
|
|
58
|
|
|
|
|
|
|
If start and end number is negative, they are subtracted from the |
59
|
|
|
|
|
|
|
maxmum line number. If the end number is prefixed by plus (`+') sign, |
60
|
|
|
|
|
|
|
it is summed with start number. Next commands print top and last 10 |
61
|
|
|
|
|
|
|
lines respectively. |
62
|
|
|
|
|
|
|
|
63
|
|
|
|
|
|
|
greple -Mline -L :+9 # top 10 lines |
64
|
|
|
|
|
|
|
greple -Mline -L -9: # last 10 lines |
65
|
|
|
|
|
|
|
|
66
|
|
|
|
|
|
|
Next example print all lines of the file, each line in four different |
67
|
|
|
|
|
|
|
colors. |
68
|
|
|
|
|
|
|
|
69
|
|
|
|
|
|
|
greple -Mline -L=1::4 -L=2::4 -L=3::4 -L=4::4 --need 1 |
70
|
|
|
|
|
|
|
|
71
|
|
|
|
|
|
|
If forth parameter is given, it describes how many lines is included |
72
|
|
|
|
|
|
|
in that step cycle. For example, next command prints top 3 lines in |
73
|
|
|
|
|
|
|
every 10 lines. |
74
|
|
|
|
|
|
|
|
75
|
|
|
|
|
|
|
greple -Mline -L ::10:3 |
76
|
|
|
|
|
|
|
|
77
|
|
|
|
|
|
|
When step count is omitted, forth value is used if available. Next |
78
|
|
|
|
|
|
|
command print every 10 lines in different colors. |
79
|
|
|
|
|
|
|
|
80
|
|
|
|
|
|
|
greple -Mline -L :::10 --ci=A /etc/services |
81
|
|
|
|
|
|
|
|
82
|
|
|
|
|
|
|
=item B=I |
83
|
|
|
|
|
|
|
|
84
|
|
|
|
|
|
|
This notation just define function spec, which can be used in |
85
|
|
|
|
|
|
|
patterns, as well as blocks and regions. Actually, B<-L>=I is |
86
|
|
|
|
|
|
|
equivalent to B<--le> B=I. |
87
|
|
|
|
|
|
|
|
88
|
|
|
|
|
|
|
Next command show patterns found in line number 1000-2000 area. |
89
|
|
|
|
|
|
|
|
90
|
|
|
|
|
|
|
greple -Mline --inside L=1000:+1000 pattern |
91
|
|
|
|
|
|
|
|
92
|
|
|
|
|
|
|
Next command prints all 10 line blocks which include the pattern. |
93
|
|
|
|
|
|
|
|
94
|
|
|
|
|
|
|
greple -Mline --block L=:::10 pattern |
95
|
|
|
|
|
|
|
|
96
|
|
|
|
|
|
|
In this case, however, it is faster and easier to use regex. |
97
|
|
|
|
|
|
|
|
98
|
|
|
|
|
|
|
greple --block '(.*\n){1,10}' pattern |
99
|
|
|
|
|
|
|
|
100
|
|
|
|
|
|
|
=item B<--offload>=I |
101
|
|
|
|
|
|
|
|
102
|
|
|
|
|
|
|
Set the offload command to retrieve the desired line numbers. The |
103
|
|
|
|
|
|
|
numbers in the output, starting at the beginning of the line, are |
104
|
|
|
|
|
|
|
treated as line numbers. This is compatible with B output. |
105

|
Using this module, it is impossible to give single C in command |
109
|
|
|
|
|
|
|
line arguments. Use like B<--le=L> to search letter C. You have a |
110
|
|
|
|
|
|
|
file named F? Stop substitution by placing C<--> before the target |
111
|
|
|
|
|
|
|
files. |
