I'm constantly going 'cd ../../../../'. Is there a command/alias that could let me go 'cmd 4' and I'd be taken back 4 directories?

I am total new to linux as I worked mostly on RTOS (symbian). My problem is, I need to find the file IOSTREAM.H and I am following commands below:
1) cd /
2) find . iostream.h ( finds the file / directory from the current path)
It shows No such File or Directory
I have an ext2 formatted disk (linux) and I need to reformat it to NTFS (windows). Problem is, I have to retain the 750 GB of data that's on the disk. What's the quickest (least number of steps) way to accomplish this? I do have a spare 1TB disk now to help with the transfer.
Background.I've been using XBMC Live for a couple of years, but with all the problems I've been having lately, I'm moving over to the Windows version. Unfortunately all of my media is stored on an ext2 formatted disk (not the same disk as the OS disk).I was thinking of loading up an Ubuntu live disk, and installing ntfs-config. Mount my secondary disk (already formatted NTFS), transfer the files, reformat the original drive, load windows and transfer the files back.
I want to be able to use Ctrl+R to have reverse-i search. Also if I press Shift+Up Arrow after typing the first few characters of a recently executed command then the shell should complete the command by finding the most recent commmand having the same first few characters.

View 2 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 3 Replies View RelatedCode:
$ echo 2 * 3 > 5 is a valid inequality. This will create a file in the current directory named '5' with the number '2' in it, the names of all the files in the current directory, followed by the number '3' and 'is a valid inequality.'
What I do not understand is why 'is a valid inequality' gets written to this file. I thought it would write '2', all the file names in the current directory, then '3' into the file called '5'. Why does the 'is a valid inequality.' get written to the file also?
Assumed y directory structure looks as follow:
Code:
--root

And under each sub dir there are some log files ended with .log. Now I want to list all these log files. How to to that?
I have just created a usb boot disk so that I can install Fedora 14.I used the following which was successfully. However, I am left wondering what does the bs parameter actually does. I know it mean bytes and copies these at a time. But how do I know what to set it to?dd if=F14-Live-i686.iso of=/dev/sdb bs=8MIn the above example it is set to 8MB. However could I set this to any value that I want?
View 1 Replies View RelatedBasically, I am trying to locate and copy the newest .json bookmark backup in my .mozilla/firefox/w987sdg9.default/bookmarkbackups directory.
I tried this
Code:
ls -t ~/.mozilla/firefox/b1ahb1ah.default/bookmarkbackups/ | head -1
which does return the newest file, but only the filename itself. I found readlink, but I haven't gotten that to output a full path which I can then feed to copy. So, it seems to me that find might work well here, and I know how to find based on absolute dates, but not relative.
I am a student studying computer science course.
Well, I am facing problem when doing lab questions.
I must use DLXLinux bundled in Bochs (bochs.sourceforge.net).
I am required to use the /usr/local directory.
In /usr directory, there is no directory named 'local' but there is one thing called 'local@'. So, when I try to use mkdir command to create 'local' directory in /usr , there are error "cannot make directory.....".
Look at my screenshot at [url].
I'm quite new to linux but I have configured a simple ftp server and it's working great. I have a FTP-Shared folder with upload and download subfolders. Under upload's and download's I have identical category subfolders like mp3's, movies, software etc. in both. As the guy's upload, I would like to create a line crontab where I can move all the content under /FTP-Shared/upload/mp3/* older than 14 day's to FTP-Shared/downloads/mp3/ recursively (Like in cp command), but the timestamp must be searched on the first directory and not sub files example: /mp3/Club Dance/CD1/Hallo world.mp3This is how far I got:[root@clients ~]# /usr/bin/find /FTP_Shared/upload/Mp3s/ -depth -mindepth 1 -mtime +14 -type d -exec mv -f {} /FTP_Shared/download/Mp3s/ ;This command moves the directory and files, but it is not recursively

I am using Xephyr to create a windowed session for logging in as another user. It needs its own X display, though. Obviously I can just give it :1.0 and hope for the best, that it would be better to identify the first free display and use that.
But I don't know how...

View 5 Replies View RelatedI 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.)
I 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.
