General :: Add (not Replacing) A Pattern Match With A Similar Pattern?

Aug 30, 2009

I'm writing a bash script to search html files, and when I find any occurrence of an img src tag like this:

<img src="123-picture-normal.jpg" alt="some random user entered text" border="0">

I want to add a second line below it that looks like:
<img src="123-picture-thumbnail.jpg" alt="some random user entered text" border="0">

All I need to do is duplicate the line but replace "normal" with "thumbnail"

Each file can have multiple img src tags with different numbered jpgs.

I have a feeling this is a job for sed, but I'm struggling with it. Any ideas?

General :: Sed Remove String Until Final Match?

Mar 20, 2010

I have been fighting with a sed statement trying to get it to remove everything in a string until the last match and have been failing badly. how to get this to work..

sed --> enterprises.9.9.171.1.5.2.1.1.5
returns 5

I want sed to strip everything out until the last period. The final digit can and will change. Some parts before the final period can change as well, since enterprises will sometimes also be represented as more numbers and periods.

General :: Selectively Remove Blank Spaces From String?

Oct 7, 2009

need all spaces between two letters or a letter and a number exchanged for an underscore, but all spaces between a letter and other characters need to remain. One example for clarity:

Input:

force -- lamin 90 [label]
active A -- generation [label]

needed Output:

force -- lamin_90 [label]
active_A -- generation [label]

I tried solving this with sed but obviously s/ /_/g does not work, nor does any s/[a-zA-z0-9] [a-zA-z0-9]/[a-zA-z0-9]_[a-zA-z0-9]/g , because you just can't do this...

Programming :: If Statement Pattern Search / End Of Pattern Special Character?

Apr 29, 2010

I have to enhance the behaviour of a backup script written in perl. I don't need to change it, what I need to do is to create a bash script that does some checks like file name and file size, execute the backup script then check if the backup files match the original files.Here's how I try to do it:

- read the files from the original files folder
- store them in an array
- search in the array the files that have a specific file extension
- store the file names that match the search pattern (I know the backup script skips some files so I can hardcode the search pattern)
- run the backup script
- read the files from the backup folder
- store them in an array
- compare the original files name and size stored in an array with those from the backup folder
- send a report email

Programming :: Remove All Alphabetic Characters At Beginning Of String

Jul 26, 2010

I am working with a Tcl script and have some strings in the following format (RE):
[a-zA-Z]+[0-9]{6}-[0-9]

There are some leading letters, combinations of capital and lowercase. Then six digits, followed by a hyphen, then one more digit. I would like to remove all of the leading alphabetic characters from the string. The resulting string would then be in this format: [0-9]{6}-[0-9]. In other words, six numeric digits, a hyphen, then one more digit.

I have tried:
Code:
set newstr [string trimleft $origstr alpha]
But that only removes the first alphabetic character, not all of them.

I couldn't get anything with regsub to work correctly, but I am somewhat of a noob with RE's in general and regsub in particular. There are usually 5 leading letters at the beginning of these strings, and I could in most cases get away with using string replace and constant indices to extract the substring. However, my preference is for this to be robust enough to handle all cases with 1 through n leading alphabetic characters.

Ubuntu :: Search For An Exact String In A Terminal?

Is there hopefully a way to search for an exact string in Man Pages? I know if I want to search for anything containing -c I can just do this.

Code:
/-c

How would I search for "-c"? I want only "-c" to show up. So I tried this.

Code:
/"-c"

It took me literally and looked for the quotes also.

Server :: Remove Dynamic String Across Multiple Lines And Files?

May 13, 2011

My server was hit with an injection script which has placed code across many of my clients files. I need a script that can remove a block of php code that spans multiple lines, multiple directories/files and is dynamic, meaning that part of the code changes. I think using find/sed is what I need but cannot seem to figure out how to get it to work.The following is the script that is being injected everywhere. The catch is that they have generated dynamic code at the start/end of the script. (I have commented the parts that are dynamically changing on EVERY instance).PLEASE NOTE: Directly following this script is the start of a valid php script that I do not want to delete.

<?php
//{{65281980 - DYNAMIC!!
GLOBAL $alreadyxxx;
