Programming :: Sed To Search And Insert Column?

Feb 24, 2011

I have the following file.

B0 49.2230869 -102.5743868
C 1LPRK 654.90
C 1PREU 3693.90
C 1JRSU 3693.90


I need to insert text ABCDEF starting at position 26 if a line starts with C. I need it to look like:

C 1VKNG ABCDEF 3097.00
C 1JLFU ABCDEF 3157.20
C 1MNVL ABCDEF 3346.10

I would prefer to use sed to do this and not perl.

Ubuntu :: Text Editor Column Editor And Regex Search/replace, Incrementing Number Insert?

Jul 25, 2011

On windows I really only used Notepad++ as my text editor, it had two features that I loved.What I need to accomplish is what I would do with Notepad++ column editor.I could have like 100 lines, and place the cursor at a column, and goto edit>column editor, and I could insert an incrementing number. (I could also pad the incrementing number with 0s, this was GREAT for making batch files among other things.)So each line at that column had a number higher than the previous line.The other feature that I used sometimes was a search/replace with regex patterns.Does anyone know of an editor that has those features for linux? I am mostly after the column editor insert feature but if you know of one with both features that would rock.

Programming :: Sed One-liner: Search Text In File And Replace It - If Not Present Insert It?

Oct 16, 2010

As indicated in the subject, I want to search a text. If the text is present I want to replace it. But if the text is not present, I want to insert it after first line and before last line.

Searched text is:CleanCache "*";

Where * can be anything.

Example: CleanCache "false"; -> CleanCache "true";

If CleanCache "false"; is not present, only insert CleanCache "true"; after first line and before last line.

General :: Insert Column With Awk / Sed Between Two?

Jan 18, 2011

I have a two column file and I need to create a new column in between the first and second but the new column adds a value to the first. E.g.code...

I thought I had figured out how to do it with the following but it just hangs:

awk -F '{print $0,$0+25,$1}' file_in > file_out

Also tried the following to no avail:

awk -F,-v OFS,'{print $0,$0+25,$1}' file_in > file_out

I can add the new column with the added value to the last column easy ( awk '{print $0,$0+25}' file_in > file_out).

Programming :: Postgresql Put '' In Column?

Apr 9, 2010

Problem is simple but I can't figure out how to solve it, I tried any possible way that I know but with no result.I'm using simple perl script with DBI and do select from one table and do update in other table with results from select, but I can't preserve my '' returned from select when doing update. I simply want my '' from first table to be '' in second but postgres makes them real new lines. I tried to escape '' with , '',"",E(I mean E'value here') in front of value that updating but they are always real new lines not '' in new table.

Programming :: Bash Awk Column To End Of File?

Sep 4, 2010


ls -lhGg | while read line; do echo "$line"; done | awk ' { print $3" "$6 } '

what i want to do is be able to print column 3 and every column greater then 5. Has to be to the end of the line, since different filenames can have different amounts of words in them and the blank space is the separator. my current code works just fine if the file has no blank space.

Programming :: PHP - Sorting Multi Dimensional Arrays By One Column

Mar 17, 2009

I just started programming in PHP so I haven't figured out how to do this yet, but I have a multi-dimensional array that I need to sort by one column. That's fine...but I need the sort to ignore case! Right now I have it sorted by 'name' (the other column is 'uid').

The problem is that by the default the sort is case-sensitive so the array looks like this:
Apple 4015
Banana 4011
Cherry 4045
avocado 4046

I want to be able to sort the the 'name' column in a case-insensitive manner so that the array actually looks like:
Apple 4015
avocado 4046
Banana 4011
Cherry 4045

How to accomplish this? Just FYI I'm not actually sorting the PLUs for fruits...but it was a simple example. I'm actually doing this for a Facebook application.

Programming :: MySQL And PHP - Table Column With Multiple Values?

Dec 1, 2008

I am writing a script to mine data from my game server logs which are going to mysql. My first question is syslog-ng is sticking $msg into one colum it self, $msg tends to be a long string here are a few examples:

cn name team frag death flags role host.
0 Maik CLA 2 0 0 normal *.70.233.118.
1 lizardncd RVSF -1 3 0 normal
[*.22.247.40] lizardncd fragged Maik.

And they are not always in the same format, How could I parse this data to do something useful, like creating a user stats page with frag counts and flag counts. Should I create a script that runs in a cronjob that parses this data to a new table maybe once a day. Even then the $msg string value is random and I am thinking in terms of awk.

Second. I would like to keep track of what ip's are using what nicknames. Kinda in the sense of and ip associated to a array of names that have been used on that ip address so I can keep track of users. How would this work logically with a mysql db, could a column allow multiple values, then loadable into an array, which then can add, remove, and store to mysql.
