hi guys! I`ll really appreciate your help.
The situation is:
i have a log file, and i need to get the needed lines from it.
1-string gets the number of found lines
2-string gets the string numbers
What I need is to make script to get next 5 lines after each found $lines. For example:
echo $lines
287 309 331
so the needed strings are 287-292, 309-314, 331-336.
my idea was to make something like:
it would be great if someone could show a quick solution of how to do that or just some suggestions!
Thanks!

I'm trying to search for lines ending with "}" with the following command but am not getting any output.
grep '\}$' myFile.txt
I actually want to negate this (i.e. lines not ending with "}"), but I guess that should be easier once I find the command that finds it? (11 Replies)
What is the best way to display lines in a log file that begin with a certain string?
Preferably I would like to 'print' them to a file. I guess I would use 'cat' for that?

It would be something... (8 Replies)

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.

Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
