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
Assumed y directory structure looks as follow:
Code:
--root
-- dir1
-- dir1-1
-- dir2
-- dir2-1
-- dir2-2
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 am reading about jiffies in linux kernel. In one of the related example in the book Linux Device Driver, the author use
head -8 /proc/currentime
to print out some time information.
However this file is not present in my linux installation (kernel: 2.6.32-131.6.1.el6.x86_64). Why is it the case? Is it because the file path is no longer valid, or it is a distribution feature thing? It is not present in OSX too. What would be an equivalent in OSX?
I have been playing around with the tar command and I know this is how to use it.
Code:

View 1 Replies View RelatedI have several directories of subtitles for some videos, but all the text for the subtitles in each file is in uppercase, and I would like to convert the files' content to lowercase, all in one go. I found on a website a bash command that would do each file separately:tr '[:upper:]' '[:lower:]' <input.txt> output.txt but of course involves specifying the input name and output name for each file.I have been trying to do it in a script that would work for all files in the current directory, without having to rename them each time, if that's possible. So far I've got the following, which doesn't work:
#!/bin/bash
for file in $@; do
tr '[:upper:]' '[:lower:]'
done
However, my web searches cannot locate a way of specifying "each file in current directory" in conjunction with the "tr" command, but also without having to rename the file once converted to lowercase. Is it possible, or would the tr command have to create a new file for each converted file?
Basically, 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'm trying to compile a program from source. When I run make the following appears:./ config. status --recheck make: ./config.status: Command not found make: *** [config.status] Error 127.There is no file called config. status in the current directory. Why was it not created?

$ 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?

If there is a command I can use to find specific file types? Say if I want to find all the jpg's in my home folder, but they don't have the .jpg extension in the name, how would I do it? Or can I set some kind of size parameter to find them? The ones I want are all from my digicam and roughly the same size.

View 14 Replies View RelatedI am working on getting my software packages installed on my fresh Slackware64-13.0 installation. Some (but definitely not all) of my executables are unable to be run.
I understand what PATH is for. It is for locating files, folders, executables in those directories when running from a Terminal window.
So, for example, I have just installed Cisco VPN Client for Linux, and it is the strangest thing. I should have access to this. I must not be understanding something here. Does anyone have any idea why this is not working for me? I have put in an example of what I am talking about.
I have no idea why this is not working.
I use this command:
Code:
find ./ -atime +360
to figure out the files that haven't been accessed since 360 days. The command above will return results like this:
Code:
/uploads/2010/02/some-file-name.ext
/uploads/2009/08/another-file-name.ext
... etc
I'm taking here about tins of directories, thousands of files. I'm looking to find a command that makes me able to move the results above to another path, and to create that path once it doesn't exist like below:
Code:
mv /uploads/2010/02/some-file-name.ext /old-files/uploads/2010/02/some-file-name.ext
But I want the executed command to create this path
Code:
/old-files/uploads/2010/02/
If it doesn't exist.
What 's the most popular command to do such things in terminal in linux?

I need to write a script that is given a directory as an argument, and it prints the last modified file from that directory and all its subdirectories.

If I had to do it only for the current dir, it would be easy...I'd probably use "ls -lt" and then show only the first line...
I really missed the old Ubuntu file/dir. copying feature. When I copied in nautilus file explorer and paste into a terminal or text editor, I got the exact path (eg. /home/user/abc.txt), but when coming the Ubuntu 10.04, it added some "file://" prefix to the actual path (eg. file:///home/user/abc.txt), and I always had to manually delete the "file://" prefix. I don't see clearly that we need to place "file://" in front of the actual path (maybe just in the case we want to put the path in an Internet browser?). Wish this reversed back.

### TO DO: Determine the report file name based on the source directory name and current date### The report name and thumbnail directory must follow this pattern: source-%j-%H### for example, for pictures in /home/you/pictures, the file name will be: pictures-%j-%H### HINT: Use sed to extract the directory name from the path and combine it with date command output
