General :: Insert A Line Into A Text File Using "sed" Command?
Sep 18, 2010I've been reading tutorials of Linux sed command, but haven't got anything yet. the problem is : I want to insert a line into my DNS database file which has a pattern like below:
<Domain name> 3tabs here <IN> <A> <ip address>
the question is : how to add a line into a file like this using linux sed command? I have problem inserting tabs and the spaces!
Programming :: Insert Line Of Text Prior To Pattern Only Once?
Jun 29, 2010I have a file like so:
Code:
one
two
three
four
I would like to insert prior to the word "three" all items from this second file with the following contents:
Code:
four
three
two
one
Now my issue is, and I have been using both sed and awk currently, that after the second line of the new file is read there will of course now be 2 copies of the word "three" but I would like to only insert the final 2 words, ie "two" and "one" prior to only the first occurrence of the word "three" so final file will look like:
Code:
one
two
four
[code]....
So here there is now only one of each word from the second file joined to make the new file. For simple code I have tried something like the following:
Code:
while read line
do
awk -v n=$line '!f && /three/{print n;f++}1' file1 > tmp_file
mv tmp_file file1
done < file2
Now this works but seems very clumsy to me. There is obviously a better sed and / or awk out there.

General :: Insert Character Code Into Text Editor?
Aug 11, 2010I need a lightweight GUI text editor on my Ubuntu Lucid system which lets me specify a Unicode code point (e.g. U+1234), and inserts that character to a UTF-8 text document. I know that gedit can't do it (not even with the Character Map plugin).
I'm not interested in solutions involving any kind of emacs or vi. I'm also not interested in text editors running in the terminal (such as joe, which has this functionality). I need the absolute simplest, smallest and fastest plain text editor for Linux which lets me type a few letters, insert a few characters by their code, type some more letters, and then save the .txt file as UTF-8-encoded.

General :: Insert Tab At Beginning Of Each Line In File?
Aug 5, 2010I am trying to create a shell script where a user can specify a file with a list of logins and the script will create a batch file with specific information in specific columns.
Example:
loginfile.txt has
User1
User2
User3
I need the output to be as below:
1 User1 Date 12/31/9999
2 User2 Date 12/31/9999
3 User3 Date 12/31/9999
Where the columns are separated as below.
1[tab][tab]User1[tab]date +%D[tab]12/31/9999
2[tab][tab]User2[tab]date +%D[tab]12/31/9999
3[tab][tab]User3[tab]date +%D[tab]12/31/9999
I can use the nl utility to get the numbers easily enough, but I need two tab separations between the number and the user list. Is there a sed command that will insert at the beginning of each line? If so I can just run nl after I get some tabs up in the front.

Jun 4, 2011Is 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.

Programming :: Sed Insert Line With Leading Spaces?
Mar 3, 2011I'm trying to insert a line using sed that has leading spaces before the text. Sed seems to be just dropping the spaces and only inserting the text. Any ideas what I'm missing?
Code:
NAM=rb134
sed -i.bak -e "$i
host ${NAM} {" /etc/crap
Instead of inserting a line with 8 leading spaces inserts it with "host" at the beginning of the line. I tried
Code:
NAM=rb134
sed -i.bak -e "$i
^ host ${NAM} {" /etc/crap
but it put the "^" at the begging of the line.
General :: Getting Numbers From A Line Of Text?
May 10, 2010 I'm working with a rather large file of data taking from a tracking program on my phone, and trying to pull only the longitude and latitude from it. Any given line in the data looks more or less like this:
{"lon":-122.3083848,"time":1.273515839496E9,"source":"skyhook","nap":28,"altitude":0,"name":"location","hpe" :29,"bearing":0,"ncell":0,"lat":47.6544453}
I've run it through this command:
grep skyhook log-2010-05-10_18-17-28.json | cut -d"," -f1,10
to get this:
{"lon":-122.30872015,"lat":47.65812201}
{"lon":-122.3076686,"lat":47.6569975}
{"lon":-122.3079161,"lat":47.656395}
{"lon":-122.3096168,"lat":47.656218}
{"lon":-122.3096285,"lat":47.656206}
Which is a lot nicer, but I would prefer not to have to hand remove the non-number characters by hand since there are thousands of data points. what I could do to get it to just be longitude and latitude in 'number number' format?

Programming :: Delete Line Of Text From Text File Via Shell?
Jan 13, 2010I 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.
