Thank you for this andrew. This worked! How would I go about changing the time. Not 100% sure on that part (how you got it too return 8/9:00.
I would like to be able to extract a time of 23:00 - 00:00
Cheers
Alex
Basically the [...]construct matches any of the characters inside the square brackets. So if you wanted to match any time from 03:00 to 06:59 inclusive the following expression will match:
but for a contiguous series of characters one would use a range:
To match a time of 23:00-23:59 you need to change the 0[89] to 23. However you will need a separate expression to match 00:00 as, for one thing, this will be in the following day (say the 5th instead of the 4th).
Hi,
I have a .log file in which it has many values. But i need some specific values. How it can be done using Shell Script. Please explain in detail.

Hi,
Is there anyway to print contents of any file ( say log files that grow automatically) within some timeframe ( comparing with current time), say
print contents of the added in:
1) last 2 hr
2) last 45 min
3) last 3 hrs 47 min (3 Replies)
How could I using the following example, change it to show 2 days ago within the same time frame 0600 AM to 0600 AM

find . -mmin +$foo -mmin -$bar | tr -s '/','-' '^' | cut -f2,3 -d"^" | tr -s '^' ' ' |

Guys,
I am trying to use this command to find out the occurrence of the service "Loadservice" from the log file "log.06102010.svr1" in between the time frame 02:00:00 to 03:00:00 on the day 06-10-2010.

I have a log file which have a date and time at the start of every line.
I need to search the log file starting from a specific time to the end of file.
For example:
Starting point: July 29 2018 21:00:00
End point : end of file
My concern is what if the pattern of `July 29 2018 21:00:00`... (3 Replies)

fgrep
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.

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.
