Programming :: Sed Insert Line With Leading Spaces?

Mar 3, 2011

I'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.

Programming :: Insert Line Of Text Prior To Pattern Only Once?

Jun 29, 2010

I 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.

Programming :: Print A Line Of Fill Character In C?

May 15, 2010

As you know, in C++ you can use setfill(char c); and setwidth( int length) to fill a line of a character.
It's line making a line of a character for output

Code:
NAME DEPARTMENT LOCATION
==========================================
Pete R&D Chicago
...
==========================================
As you see, a line of a '=' character drawn to output.

I'm wondering, how can I draw this line in C using printf() to format?
( no loop or repetiton )

Programming :: Replace Character With Hex Value Choosing From Shell Cmd Line?

Jun 9, 2011

I am bouncing a file across platforms (windows->solaris->mainframe), and the file is starting out with a "special" character (the registered trademark "circle R") in some of the records. This character is not in the EBCDIC character set on the MF, so it is unrecognizable. The MF developer I am working with asked if it is possible to replace the character with a specific hex value (AF) before it gets to the MF.

I was putzing around with sed, tr, etc. on the ksh command line, hoping to find an easy way to get one of them to substitute hex instead of ASCII. I have found that the usual shell utilities recognize the trademark character, so homing in on what to replace is solved. But I cannot get anything to actually substitute in the hex sequence I want. E.g. I was thinking something like...

>cat special_file | sed 's/R/AF/g'

But my version of sed does not seem to have hex "editing" capability.

Programming :: Csh Shell Script - String Concatenation - Add A New Line Character?

May 4, 2009

Inside a loop i'm populating a string variable. Because csh doesn't have very good support for arrays I thought of doing this. I want to add a new line character to the end of the concatenation each time the loop iterates. Then at the end print this variable out.

I tried " and some resources said it was just a "". Neither work. What am I doing wrong?

General :: Insert Character Code Into Text Editor?

Aug 11, 2010

I 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, 2010

I 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.

Programming :: Copy And Replacing Specific Line From File1 To File2 Line By Line

Mar 22, 2011

I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.

At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.

What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.

I tried to use paste command but I cant do for specified line alone.

Here i showed the data format in the file. I used the line number for clarity purpose.
