View 11 Replies View RelatedI am a noob and I am trying to display a count of the number of subdirectories in a directory. I have been able to use find -type d to list directories and subdirs but I want a numerical value of dirs and subdirs. I know ls -l gives a count but when I try ls -l -d all it shows is "." I also have tried a combination with the -R option but nothing seems to be working for me.Please forgive my ignorance but I am working on a script for class and this is the first step.

View 4 Replies View RelatedI 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.

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:

I recently found myself in possession of a large file (a few million lines in length) of short strings and would like to count the number of lines that are unique to the file. I thought this would be an easy process, but while working on the problem, I encountered the following. Can anyone explain this weird result to me?

I'm trying to find a script that will return me the largest number of repeating characters. Say, I have the following line in a text file: 12345AAAAA6789AAA
I want it to return 5, because "A" is repeated 5 times in this line (more than 3 at the end).
How do I count the number of occurrence characters in a string in an efficeint way ?
How do I reverse the words in a string with out using temp variables if possible . (if not possible use temp variables ?

For reasons I can't even begin to figure out, the number pad does NOT work.i can get the num lock light to come on, but pressing the keys there produces no love at all. Right before I installed F10, my F8 x64 had been working flawlessly for a VERY long time and I have been able to verify that the keypad still functions both with the M$ Windoze Vi$ta virus and a live Knoppix CD.Since this is the first time I have had this issue, I don't even know where to look to consider solving this.
I did try the System->Preferences->Hardware->Keyboard and all of the HP layouts listed there, but I still can't get anything more than the Num Lock light to come on and go out.
I'm the POC for all my families Linux computers. Is it possible to get statistics on which programs are accessed, how frequently, for how long and by which user?
When it comes time to upgrade it would be useful so I know which programs to concentrate my testing. I usually just e-mail and ask but every time people forget to send me the programs they actually use.
I am trying to get the count of number of CD-ROMs attached with my Linux system using a bash shell script. I have decided to use the following method for it:
Code:
debian:~# cat /proc/sys/dev/cdrom/info | grep "drive name:"
drive name: sr0 hdb
So basically I know that there are two CD-ROMs attached to the system. Now there can be three also like this:
Code:
debian:~# cat /proc/sys/dev/cdrom/info | grep "drive name:"
drive name: sr0 sr1 hdb
All I want to do is in my shell script to get the count of the devices in a variable using the above command.

View 6 Replies View RelatedI have:
Code:
C:u002Cdatau002CDocuments
If I used:
Code:
sed 's/u0052//'
It only removes the first occurrence. How can I remove all occurrence in the line?
Almost by mistake, I figured out you could do something like:
$ cp foo.data bar1.data
$ ^bar1^bar2
And that runs the same command with bar2.data instead of bar1.data. Now, how about if I have multiple occurrences of the target word? For example:
$ cp foo.data bar.data
$ ^data^index
It only replaces the first data extension. How do I get it to replace both?

View 1 Replies View RelatedSempron 3100+, 512mb 400mhz RAM, Ubuntu 10.04 32-bit.From what I've noticed, the computer seems to primarily lock up when an internet browser is open and/or being navigated (I'm testing this observation, now). I've tried Firefox and then installed Chrome; same thing.CTRL+ALT+F1 unresponsive, mouse is frozen.Note that this is an old build given to me by a friend. The build originally had one stick of 512mb and 256mb. I took out the 256 for diagnostic purposes. Additionally, the computer originally had an nVidia 6200 graphics card, which I replaced with a 6600 I had lying around--again for diagnostic purposes. I installed the recommended video drivers respectively. After three re-installations of Ubuntu, 2 different browsers, 2 different graphics cards, running memtest86 and singling out the RAM, and using a can of air to eliminate any overheating issues, I'm unsure what to do next. I have a feeling this is operating system related, though. In BIOS, the CPU fan seems to be running at fine RPMs, but no temperature is given
Do note I am entirely new to the Ubuntu/Linux OS, and wanted a cheap, nice solution for this salvaged PC that I'm giving to my little sister. edit #1: Left the computer idling on desktop with no browser open; seemed okay for hours on end. I opened Chrome to the google homepage (with the Pac-Man flash theme at the time), and it did not freeze then as well when set to idle for hours at a time.
I'm trying to process a postscript file and I want to change alternate pages by finding the string '%%EndPageSetup' (and then adding a line after it).
I've tried using sed with labels and a branching program to ignore the odd occurrences and process the even ones. In the code below I tried searching for the first and ignoring it by jumping to next and processing it and then to the next odd page and so on.
My logic is obviously flawed here as it doesn't work but I've tried the following:
Code:
#!/bin/bash
sed -e '/%%EndPageSetup/{
b even
:odd
/%%EndPageSetup/ b even
:even
s/%%EndPageSetup/%%EndPageSetup++/ b odd}' filename.ps > newfile.ps
