So, I need to do some summing. I have an Apache log file with the following as a typical line:
127.0.0.1 - frank "GET /apache_pb.gif HTTP/1.0" 200 2326
Now, what I'd like to do is a per-minute sum. So, I can have awk tell me the individual minutes, preserving the dates(since this is a... (7 Replies)

If $1 in file1 matches $2 in file2. Then the value in $2 of file2 is updated to $1"."$2 of file2. The awk seems to only match the two files but not update. Thank you :).

I am trying to use awk to match two files that are tab-delimited. When a match is found between file1 $1 and file2 $4, $4 in file2 is updated using the $2 value in file1. If no match is found then the next line is processed. Thank you :).

I am trying to output a tab-delimited result that uses the data from a tab-delimited file to combine and subtract specific lines.
If $4 matches in each line then the first matching sequential $6 value is added to $2, unless the value is 1, then the original $2 is used (like in the case of line... (3 Replies)
In the awk below I am trying to set/update the value of $14 in file2 in
bold, using the matching NM_ in $12 or $9 in file2
with the NM_ in $2 of file1.
The lengths of $9 and $12 can be variable but what is consistent is the start pattern
will always be NM_ and the end pattern is always ;... (2 Replies)
In the perl below, which does execute, I am having trouble with the else in Rule 3. The digit in f{8} is extracted and used to update f accordinly along with the value in f.
There can be either - * or + before the number that is extracted but the same logic applies, that is if the value is greater... (5 Replies)
I have been reading old posts and trying to come up with a solution for the below: Use a tab-delimited input file to assign

Hi,
So awk is driving me crazy on this one. I have searched everywhere and read man, docs and every related post Google can find and still no luck. The actual files I need to run this on are sensitive in nature, but it is the same thing as if I needed to calculate weighted grades for multiple... (15 Replies)

split
SPLIT(1) BSD General Commands Manual SPLIT(1)NAME
split -- split a file into pieces
SYNOPSIS
split [-a suffix_length] [-b byte_count[k|m] | -l line_count -n chunk_count] [file [name]]
DESCRIPTION
The split utility reads the given file and breaks it up into files of 1000 lines each. If file is a single dash or absent, split reads from
the standard input. file itself is not altered.
The options are as follows:
-a Use suffix_length letters to form the suffix of the file name.
-b Create smaller files byte_count bytes in length. If 'k' is appended to the number, the file is split into byte_count kilobyte
pieces. If 'm' is appended to the number, the file is split into byte_count megabyte pieces.
-l Create smaller files line_count lines in length.
-n Split file into chunk_count smaller files.
If additional arguments are specified, the first is used as the name of the input file which is to be split. If a second additional argument
is specified, it is used as a prefix for the names of the files into which the file is split. In this case, each file into which the file is
split is named by the prefix followed by a lexically ordered suffix using suffix_length characters in the range ``a-z''. If -a is not speci-
fied, two letters are used as the suffix.
If the name argument is not specified, 'x' is used.
STANDARDS
The split utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
A split command appeared in Version 6 AT&T UNIX.
The -a option was introduced in NetBSD 2.0. Before that, if name was not specified, split would vary the first letter of the filename to
increase the number of possible output files. The -a option makes this unnecessary.
