Programming :: Match Datetime By The Minute (not An Exact Match By The Second)
Oct 21, 2010I have the following query:
Code:
$sql="SELECT table1.datetime, table1.user_id, table2.ip, FROM table1,table2 WHERE id='$id' AND (table1.id = table2.id AND table1.datetime = table2.datetime)";
In table2 the datetime fields are about 1 to 2 seconds off due to the source of the data, which I cannot change.
Is it possible via a query match table1.datetime & table2.datetime by HH:MM (ie. to the minute instead of to the second)?
Programming :: Sed - Add A Line After A Match?
Sep 16, 2009I need to edit the sudo file on lots of machines. I figure the easiest way is to run a for loop to ssh to each box, sed the sudoers file to a new file & copy/move back over the top of the original (and of course, change permissions accordingly)
The problem is, I'm not sure how to add a line after a match with sed.
So if my file looks like:
Code:
I'd like it to add the new sudoer after "other" so the file looks like:

Programming :: Cannot Match Strings That Appear To Be Identical
Feb 25, 2011i have an sql table with 2 columns i run a script that randomly selects a word from the table in column 1.
the word is displayed on the screen and I guess what it means i concatenate the randomly selected word and the answer the script looks for a match in mysql if it finds a match it says "Good job!" if there is no match it will say "not correct". However when i get it right it says not correct even though when i echo the variables they look exactly the same. the script below:
#!/bin/bash
var=$(mysql translator -u root --password=*-N<<EOF
SELECT word FROM tagalog ORDER BY RAND() LIMIT 1
EOF

Programming :: String Match In Perl ?
Sep 15, 2010One of my application generates a text file with an XML output in it. I need to read that log files and if the output does not match to a string in couple of tags it should create a log file with the file name and the the tag name.
The two tags where the string should match is:
Identity format tag should always be JPEG , well- formed and valid status tags should be true.

Programming :: Display All Lines Before A Match Is Found?
Sep 9, 2010I have a file, and I have to display all the lines from the beginning of the file till a matching string is found.
I know grep with "-a", "-b" as option does exist, but it needs the number of lines to be printed in advance. eg grep -b 10 "search_string" file so it will print 10 lines before a match is found.

Programming :: Sed Regular Expression Match Everything Up To A Certain Character
May 27, 2009I need to use sed to edit a file that contains just one line. This should be pretty simple, but I've googled and can't seem to figure it out. I need to match everything from a certain string up until the first comma in the line. There are multiple commas in the line and my matching pattern is matching up until the last comma, not the first.
Here is what I'm trying:
As you can see it is matching up until the last comma. Seems like the .* is matching any character including the other commas. The output from this that I am hoping to achieve:
How can I get the regular expression to match from asdf: up until the first comma?
Programming :: Use Of Uninitialized Value In Pattern Match - Perl
Jun 26, 2011I want to strip the process name from the hosts - i did it with the code below.
I have two questions - is there a more compact way to strip off the process names? usalso i want to get rid of the errors after extracting the hostname. It is complaing about $arry[1]. using my $arry[1] is not allowed. Assigning the slice to a value, as is 'my $sliced_arry = $arry[1]; print $sliced_arry , does not work either.
Code:
Use of uninitialized value in pattern match (m//) at newcomm_stats.pl3 line 7, <NEWCOMM> line 16 here i get what i want - just the host name, but still get those nasty errors. assigning a value to $1 does not work, and localizing $1 with 'my' is not allowed.

Programming :: File Renaming Based On A Pattern Match
Jan 8, 2011What I am attempting to do is rename some television shows into the format that my PVR will understand for the naming convention. I have a script that cleans them up about 95%, now I just cant figure out the last little detail..
For example: NCIS_01.mkv
I think it can be done in sed, but I just figure out how. I need it to be renamed to: NCIS_s01e01.mkv
How can I make sed (or something else) match the last "_" and any numbers after it until the period and then insert text between them reliably?
Depending on the show, it can be something like: This_show_name_243.avi so I need it to be more flexible than I can figure out how to do..
Programming :: If Statement Regex Match For White Spaces?
Apr 8, 2011I want to match for this string:
Code:
Content-Transfer-Encoding:[:space:]base64
Content-Disposition:[:space:]attachment;[:space:]filename="%variable%"
Both lines are new lines, so they won't be inline. Other than that, they are all constants, I want this regex match to be an if statement rather than returning match string. so if the $content variable contains some string that matches:
Code:
if `sed "//p"` ;
Programming :: Find A Proper Regex To Match The Two Numbers?
Nov 10, 2010am trying to find a proper regex to match the two numbers in the following log entry.
Code:

15:08:16.142 ERR [Uniform test code=64469]
Basically the pattern I'm looking for will match the two different numbers spanned across two lines.Thought I need to use multi-line mode as follow but this doesn't match on [URL]...
Code:
/^($[0-9]{5}
[0-9]{5})$/m;
Programming :: Sed - Awk - Perl - Merge Lines Unless They Match A Certain String
Apr 15, 2011What is the best way to merge lines, in sed, awk or perl, that occur between certain strings? I'm new to sed scripting and I have been working on this for some time now. I have a large file (sample below) that I need to edit.
What I need looks something like this.
I'm working with a very large file so simply merging all the lines then adding a new line character before ">contig" and after "translated" won't work, at least not with sed.
Programming :: Sed - Match One Line Make A Substitution A Few Lines Down?
Jun 6, 2011I need a substitution of a particular string (StringA) with another string (StringB). However, there may be more than one occurrence of StringA within the file, but only one instance needs to be changed, which is why I'm trying to be sure of it's positioning against something I know will be unique in the file, and will always have the same distance from the string to be replaced. So, I intend to match on a string (StringC) above the string to be substituted and then have sed go to StringA below and replace with StringB.
So far, I have had some success with the following:
Code:
... but I can't help thinking that there *has* to be a cleaner way of doing it.
Programming :: Sed Regex Get Multiple String Match In Array?
Apr 8, 2011I have a sed match that matches for certain string of a regex expression:
Code:
tname=$(echo "$contents" | sed -n 'some pattern')
How do I match for multiple strings in the $contents and return them as an array? for example
Code:
contents="this is a text, just to match patterns, here is another text to be matched"
the sed func would be able to recognize both "text"s, but only one is outputted?
Possible to put it in an array? so ${bar[0]} gives one and ${bar[1]} gives another
Programming :: Add A Character To The End Of A Line When A Certain Match Text Is Matched?

View 1 Replies View RelatedProgramming :: Unable To Match Across Multiple Lines In Perl
May 11, 2011I'm trying to split a text file into various parts. Everything in between "123" and "break" (including linebreaks) goes into the splitted file.
e.g. using this text file:
This should split into 4 files. However I'm only getting 2 files: one for the line "123break" and one for "123 blah break". The two occurrences that contain linebreaks are being ignored. The .* part of my match should capture linebreaks seeing that I'm using the /s modifier shouldn't it? Even when I use the match /(123 break)/gs it still doesn't capture the first occurrence. I'm using Perl v5.12.3 (from ActiveState) on Windows XP. The text file is also in Windows format.
Code listed below.
The above code generates two files Output_1.txt and Output_2.txt which contain "123break" and "123 blah break" respectively. I want it to generate four files.
Programming :: Perl Match Character - Random Sentence Generator ?
Aug 11, 2010I am trying to make a random sentence generator in perl. So far I can loop it x times to make a fixed quantity of words, but I don't want to do that. Or I can let it go on until I hit ctrl-C :/
I want to have it so that when it reaches a word with a sentence terminating punctuation mark it stops.
My attempt to do that was with:
This is doing the woooosh text until ctrl-C thing...
Now however I am not sure how I can cut off everything after the punctuation mark (when it exists).
