I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.I've wrestled with sed, but lost.

I am thinking of appending something to each line in a text file with Java. I prefer not write a new file with content appended from the old one.That 'something' would probably be Time Stamp when the file is created (which is same for each line).I am not sure Java provide some easy way for it or not

Can I use sed to include a text file in the beginning of other text files inside a folder and its subfolders? So it should be recursive.
View 4 Replies View RelatedWas wondering if any perl guru's could help me with a quick log file adjustment. I have a text file that looks like so (tabs and newlines are revealed so you can see what separates the data):
There are maybe 100 lines of text in this file at any given time. I need to delete all duplicate lines only looking at the first bit of text prior to the first tab. It doesn't matter which one gets deleted as long as there are no two lines that begin with that same text at the beginning before the first tab. So in this example, either the fist line "1234" or the last line "1234" would need to be deleted. I already have code in my script that opens the files - I just need the code to read the text into an array and the part that would find matches based on the above criteria, and make the deletions.
If it would be easier, I can even do a system call and use SED (v4.1.5) and/or AWK (3.1.5) instead.
I want to append some text to the file, files are mostly big, more then 100 mb. I found the cat command, so I can create a new txt file and then append it to the original file with it. Two questions:
1. Can I append text to the file instead of creating the new file and then appending it to the original file? eg:
Code:
cat file.avi "some text" > newfile.avi
2. cat takes several seconds to execute the merging files together, it seems that it is reading the original file first, is there a way skip the reading and just append the file?
How do you append text to an entry in an existing file? For example, lets say I have a file called "env.logon" in /home/myself/bin that contains the following text:
PATH=/bin:/sbin If I wanted to add, via command line, ":/usr/bin:/usr/sbin" to the PATH= and I
used the "echo" command (echo "PATH=:/usr/bin:/usr/sbin) it would create a second entry and my file would look like:
PATH=/bin:/sbin
PATH=:/usr/bin:/usr/sbin
What I want is for it to look like:
PATH=/bin:/sbin:/usr/bin:/usr/sbin
Is there a way to get this result via command line?

may be an advanced question but I need to know how to do this. Here at work I am in charge of recruiting and we have about 1,000 resumes in already. All of the resumes are in a .pdf format. I need to rename every .pdf in the following format:{firstnameLastname}.pdfThe only way I know how to do this is to convert all the .pdf files to text, extract the name out of the first few lines of text, import into excel, and then use VBA to rename the files in mass:Here is my logic so far:~Deskop/a = houses all the .pdfresumesOpen terminal: Code: cd ~/Desktop/afor f in *.pdf; do pdftotext -raw $f; done That will convert all of the preceding resumes into text filesNow I would like to append the name of the text file into the last line of the text file. So, for example, for Resume1.txt, I want to append "Resume1.txt" to the last line within Resume1.txt. So after I run the command I open Resume1.txt and on the last line within I want to see "Resume1.txt" on the last line, at the end of the resume.How can I do this? I would like to use a loop and have the terminal append the filename to the body of the text file until all of the have been appended.

I'm doing an assignment for school, and while we have not yet learned regular expressions, my teacher would like us to use AWK to append text to certain lines in a file. What we've had to do is creating a listing of all links and directories in the /etc folder and place them in a text file. From this, we were to cut the first field (Permissions) and the ninth field (filename) and create another text file. Now the part that I'm struggling with is this and I'm not sure if I should be using sed or awk. We're supposed to ADD the text "DIR" to the beginning of any line that is a directory, and "LNK" to any that is a link, like so:
DIRdrwxr-xr-x redhat-lsb
DIRdrwxr-xr-x rhgb
LNKlrwxrwxrwx rnDIRc.key
DIRdrwxr-xr-x rpm
Obviously, I realize that the first character in the permissions denotes what sort of file it is, hence when I created my text file I used
ls -l | grep "^d" > file.txt
and
ls -l | grep "^l" >> file.txt
I'd like to learn how to properly do this, but struggling through pages on the internet hasn't been helping, nor has the --help command. Therefore, while I would like the answer, I'd also like to know what the heck I'm doing For example, I know I could delete lines with regex using d/[STUFF I WANT TO DELETE]/g (To get rid of all occurences) and I can substitute using s/foo/bar But I'm unaware of anyway to ADD text upon certain occurences, let alone two different circumstances.
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.

I want to display the contents of a particular log file (simple text file, I mean in Linux). But there is a problem: The contents need to be organized in a fixed format. Have a look at this log file:
sampleLog.txt
Code:
User Name: XYZ
Reported Problems Description: Blah! Blah! Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah!

So, while displaying the contents of above file on a web page, I want to format the field names found in the log file: User Name:, Reported Problems Description:, and Remarks:. These fields may contain a variable length of text and no specific line number is assumed for them to appear on.
The desired output should look like this:
User Name: XYZ
Reported Problems Description: Blah! Blah! Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah!

I have a lot a folders, each named by a number, and in each of these folders I have a specific file (stddev.dat) containing a single line (of numbers) I need to have a single file with each line being one of the stddev.dat (no matter if it is sorted or not), and also I need to add at the begining of each line the number of the folder it comes from.
I 'm no bash expert, and the "add at the begining of the line" is a bit of problem to me". Here is what I've come up with so far, just to put everything in one file, (and also if you know a better/more elegant way to do the same thing I've done, I'm listening)

View 16 Replies View Relatedif you execute :

then the string "some textstring " will be APPENDED to logfile.txt Is there a redirect way that in stead of appended, the string will be INSERTED at the top of the logfile.txt file ?

Is there some kind of universally recognized pragma that one can insert at the beginning of a text document to designate it to be UTF-8 encoded (or any other encoding)? I've seen certain editors insert encoding comments, and one or two compilers that have an encoding pragma. But I was wondering if anyone has tried to establish some kind of universal tag format for text documents.

The $ in this particular regex (regular expression) means end of the line.
The ; is what you're subbing. This works fine and well, but what if you want to append a / at the end of the line?
