do you mean the count of matching lines? If so, then -c option will do it. From man page on a NetBSD system:
Hello milhan,
If you see OP's question carefully, OP needs to know total number of matched count of string NOT number of lines and as per your posted quote seems -c Option gives matched number of lines.
Take an example where a line contains a string in 5 lines but one line is having string 2 in a line then count should come 2 but this will not be the case as per man page lines you showed, though I can't test it as I am not in box as of now.
IMHO awk could be a choice for this one.
Thanks,
R. Singh
This User Gave Thanks to RavinderSingh13 For This Post:
When I type a command at the command line it supplies one result and the exact same command in a script
egrep '^01|^02|^03|^04' file > fileout
count = 29353
same count in the script yields a count of 23492
is there any reason this could be happening. (1 Reply)
On our one HP-UX 11i box, we have some very long paths defined. When I want to check on our user processes running, the resulting paths are chopped off. /xyz/abc/123/......./server/b is really a process running in the ..../server/bin directory. Is this a terminal problem or buffer length... (1 Reply)

Hi,
I have a log file without date/time, and I want that everytime tail|grep find something it displays the date/time and the line. I have tried something like this command but without any luck to display the date/time:

I'm using the command grep -l XYZ to get a list of files containing the string XYZ. Then I using the comand ls -l ABC to get the create date timestamp of the each file. I've tried combining the comands using the pipe command, grep -l XYZ | ls -l, but its not working. What am I doing wrong? (3 Replies)
Can I modify the grep command to show only a process name?
Currently I run ps -efa | grep chk_web to get the following:
mousr 3395 1 0 09:36:06 pts/10 0:00 sh /var/opt/scripts/chk_web.sh
Can this be changed in any way to get only:
/var/opt/scripts/chk_web.sh or chk_web.sh.

Hi,
I am currently reading a tar file and searching for a particular word using grep e.g. Plane. At the moment, if a sentence is found with the word "Plane" the sentence itself is piped to another file.

grep
GREP(1) General Commands Manual GREP(1)NAME
grep, egrep, fgrep - search a file for a pattern
SYNOPSIS
grep [ option ] ... expression [ file ] ...
egrep [ option ] ... [ expression ] [ file ] ...
fgrep [ option ] ... [ strings ] [ file ]
DESCRIPTION
Commands of the grep family search the input files (standard input default) for lines matching a pattern. Normally, each line found is
copied to the standard output. Grep patterns are limited regular expressions in the style of ex(1); it uses a compact nondeterministic
algorithm. Egrep patterns are full regular expressions; it uses a fast deterministic algorithm that sometimes needs exponential space.
Fgrep patterns are fixed strings; it is fast and compact. The following options are recognized.
-v All lines but those matching are printed.
-x (Exact) only lines matched in their entirety are printed (fgrep only).
-c Only a count of matching lines is printed.
-l The names of files with matching lines are listed (once) separated by newlines.
-n Each line is preceded by its relative line number in the file.
-b Each line is preceded by the block number on which it was found. This is sometimes useful in locating disk block numbers by con-
text.
-i The case of letters is ignored in making comparisons -- that is, upper and lower case are considered identical. This applies to
grep and fgrep only.
-s Silent mode. Nothing is printed (except error messages). This is useful for checking the error status.
-w The expression is searched for as a word (as if surrounded by `<' and `>', see ex(1).) (grep only)
-e expression
Same as a simple expression argument, but useful when the expression begins with a -.
-f file
The regular expression (egrep) or string list (fgrep) is taken from the file.
In all cases the file name is shown if there is more than one input file. Care should be taken when using the characters $ * [ ^ | ( ) and
in the expression as they are also meaningful to the Shell. It is safest to enclose the entire expression argument in single quotes ' '.
Fgrep searches for lines that contain one of the (newline-separated) strings.
Egrep accepts extended regular expressions. In the following description `character' excludes newline:
A followed by a single character other than newline matches that character.
The character ^ matches the beginning of a line.
The character $ matches the end of a line.
A . (period) matches any character.
A single character not otherwise endowed with special meaning matches that character.
A string enclosed in brackets [] matches any single character from the string. Ranges of ASCII character codes may be abbreviated
as in `a-z0-9'. A ] may occur only as the first character of the string. A literal - must be placed where it can't be mistaken as
a range indicator.
A regular expression followed by an * (asterisk) matches a sequence of 0 or more matches of the regular expression. A regular
expression followed by a + (plus) matches a sequence of 1 or more matches of the regular expression. A regular expression followed
by a ? (question mark) matches a sequence of 0 or 1 matches of the regular expression.
Two regular expressions concatenated match a match of the first followed by a match of the second.
Two regular expressions separated by | or newline match either a match for the first or a match for the second.
A regular expression enclosed in parentheses matches a match for the regular expression.
The order of precedence of operators at the same parenthesis level is [] then *+? then concatenation then | and newline.
Ideally there should be only one grep, but we don't know a single algorithm that spans a wide enough range of space-time tradeoffs.
SEE ALSO ex(1), sed(1), sh(1)DIAGNOSTICS
Exit status is 0 if any matches are found, 1 if none, 2 for syntax errors or inaccessible files.
BUGS
Lines are limited to 256 characters; longer lines are truncated.
