Programming :: Count The Number Of Slashes In Each Line?
Jan 18, 2010I have a file with lines that look like this:
Dev/7_Texas2004/4_Caves/page.htm
Dev/7_Texas2004/5_SanMarcos/page.htm
Dev/7_Texas2004/6_Austin/page.htm
And I'm trying to count the number of slashes in each line. I figured (with my limited knowledge of bash) that the best thing to use would be sed. So I ran this to print "not /": sed '!s////g' file # and eventually adding " | wc -m" to it. and I got the same result as if I ran cat, no modification at all:

Jan 23, 2011I found a strange problem when I use gdb in eclipse to debug. When I step in the program, the register RIP(I'm using x86_64 machine and that's EIP in 32 bit mode) shows correctly but the line stepping in the source code may be far from the correct line. For example, when there is no loop in the source code, the RIP keeps on increasing and the current instruction pointer goes back to several lines back. I'm sure the source code is the right one because I when I checked the memory and local variables after several lines the values are all correct. The source code has many empty lines and does it matters with GDB?

Ubuntu :: C Code Next Number In Series
Sep 17, 2010I have been looking at Open Office calc to work the next in a series if non-linear numbers, and calc does do a very good best fit and shows the equation. Just what I want. I now want to programme this into a C routine that I am writing so that the programme will both look-up what it can from a samples database, and extend them forward where it does not have enough samples. (I'm trying to understand some correlations). My thought at present is to take the Ooo calc formula and write it into my code. Before I do so, I wonder if anyone knows of any non-linear solver routines written in C that I could just plug in? I'm trying to do a best fit from only about 6 very accurate floats which graph like a curve.

Mar 22, 2011I 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.

Software :: Filter A Large Document By Line Number?
Feb 17, 2010I have a 50000 line(ish) set of records in a file.

How can I access those lines which I want to isolate into a single file? I have all the usual linux stuff available and a bit of understanding of regexps.
Software :: Finding The Right File With Only A Line And Column Number?
Aug 1, 2011I tried to come up with a thread title that was specific without being too long or cryptic. Don't think I succeeded. In my PHP error log I keep getting this error over and over again:
Code:
EntityRef: expecting ';' at line 565, column 81
It's very odd to me that it doesn't contain any sort of stack trace or file info. I know which of my virtual hosts and therefore which directory it's coming from, and it's happened now on half a dozen different servers that this site has lived on. So obviously I'm trying to track it down and add the missing ';' to the right file. This directory has dozens of sub-directories and hundreds of files though.
This is the best I've managed to come up with so far:
Code:
find . -type f -iname "*.php" -print -exec awk 'NR==565' {} ;
(I've run it both with and without the -iname filter.)
I get a very large list of files, and some of them display the contents of line 565 after them. I've checked through a number of them there, but haven't found the culprit. Is it possible to limit my "find" command to only files that have at least 565 lines? Is it possible to have it only print matches from line 565 that has at least 81 columns? How would I modify that to print perhaps 5 lines on either side (in case the error reporting is pulling a slightly different line.)
OpenSUSE :: Vi Editor Ctrl-g Does Not Display Cursor Line Number
Aug 5, 2010On Solaris UNIX, pressing Ctrl-g displays the line number for the cursor position.
i.e. line 1 0f n* --0%--

i.e. n* lines --8%--
Anyway I can make vi display hard line just like Solaris?
General :: Sed - Csv Averages On Command Line - Take The Average Of All Rows With The Same 1st Number(key)
Jul 20, 2010I have a big file full of records like this
1, 2, 4, 5, 6
1, 3, 5, 6, 3
1, 4, 5, 6, 6
2, 4, 5, 5, 5
2, 3, 4, 5, 2
anyway i need to take the average of all rows with the same 1st number(key). i.e.
1, 3, 4.66, 5.66, 5
2, 3.5, 4.5, 5, 3.5
I know this is something awk/sed would be great for, i just dont have enough experience with them to accomplish it, Also, what about averaging those columns together? so, after I output this to a file, id like to get another like:
1, 4.58
1, 4.125
The number of colums to add might not always be 4 either. EDIT: this might be easier to do in gnuplot, so I mainly just need an answer to the first part.

I'm writing a Nagios plugin to check our Oracle tablespaces and the output is given in one line like this: 1.04007771 TEMP 0 UNDOTBS1 .005340579 USERS 0 7 rows selected. I've been playing around with sed like below to delete the obsolete info and change every second space into a newline:

how many tablespaces there are so I'd have to check all databases and 'hardcode' the tablespaces in my script. Is there any way to 'automate' this knowing that 'rows selected' preceded by a number is always the last line and using a sort of counter to auto-adjust the number to put in the -e 's/ / /2' part?
