General :: How Many Files Are In Lab07 Directory?
Jun 18, 2010
So I am taking an half online/ half go to school class. I am working on an assignment that is due tonight by midnight. I am kind of confused on this question and am waiting on an email from my instructor but only have 2.5 hrs left til it's done. Here is the question.Use file globbing to copy all the files in the /labs/data directory that end with a .out to the lab07 directory. How many files are in the lab07 directory?when I ls -l into this directory. I don't see any files with that extension. Is there an easier way that I am missing such as. cp /labs/data *.out > lab07 ??? Someone help?

Is there a way, on Linux, to cause all new files created in a directory to be owned by the directory's group instead of the creating user's group?

I want to run a cronjob every 15 minutes that checks a directory for files. If the directory contains more than ten files I want it to send an email to me.
All I have is this...
*/15 * * * * ls -l | wc -l | [filename] | mail -s "This is just a test" [email address]
I would rather not write a bash script. Is there an easier way to do this? I was looking into some commands like find and grep.

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

If I have a directory /foo with a few files in it, how do I symlink each entry in /foo into /bar/? For instance, if /foo has the files a, b and c, I want to create three symlinks:
/bar/a -> /foo/a
/bar/b -> /foo/b
/bar/c -> /foo/c

How would i go about copying files to a directory, yet skip the files that already exist in the directory, and also remove the files that are in the directory. For example:
Code:
$ls /dir1
img001.jpg
img002.jpg
[code]....
Now i would like to copy from dir1 to dir2, but the contents of dir2 would be:
Code:
$ls /dir2
img003.jpg

I am using my media server as my podcast collector. I am in the process of learning the ins and outs of NFS so i can mount a NFS directory and transfer my podcasts from server to player. For now i am using scp to transfer podcasts from server to desktop then to player. The problem is the path to the directory of one of the podcasts is /home/user/gpodder-downloads/The BILL&TIMMY Show Podcast.
whenever i try and run my scp command it fails because it thinks that TIMMY is a script i want to run in the background. I have tried to back-slash escape the character, i've tried single quoting and double quoting the character and i still get the same problem. as it sits now i have to move all podcasts to another directory and then transfer them to my desktop...but i would like to transfer the podcasts without un-necessary steps.

I'm always hesitant to use /var/tmp/, because I never quite know exactly how long the files are kept there for, or even what the directory is used for. What determines when a file gets removed from /var/tmp/, and how is the directory intended to be used?

I have a USB drive that I boot using SysLinux. I think select one of several options to complete a task. I do not have access to edit those Kernels. I need to add a option from the Syslinux menu where I can delete all the files from a specific directory.

I created a directory somewhere with permissions rwxrwxr-x so that other users in my group can create files and directories in it.
I do need to be able to delete the contents in this "public" directory, but it seems that while I am able to remove any files in this directory I cannot remove and subdirectories under it.
Is there a way to remove such subdirectories owned by others under a directory owned by me?

I have a really deep directory tree on my Linux box. I would like to count all of the files in that path, including all of the subdirectories.
For instance, given this directory tree:
/home/blue
/home/red
/home/dir/green
/home/dir/yellow
/home/otherDir/
If I pass in /home, I would like for it to return 4 files. Or, bonus points if it returns 4 files, 2 directories. Basically, I want the equivalent of right-clicking a folder on Windows and selecting properties and seeing how many files/folders are contained in that folder.
How can I most easily do this? I have a solution involving a Python script I wrote, but why isn't this as easy as running ls | wc or similar?

I run a script which generated about 10k files in a directory. I just discovered that there is a bug in the script which causes some filenames to have a carriage return (presumably a '' character).
I want to run a sed command to remove the carriage return from the filenames.
Anyone knows which params to pass to sed to clean up the filenames in the manner described?
I am running on Linux (Ubuntu)
The character causing the filename to 'break up' accross multiple lines appear to be a CR (carriage return) instead of ' '. The filename is being diaplayed in thetitle of a text editor with %0D in the positions of where the file name breaks up. So I need to remove the CR chars from my filenames.

but this lists all the files in the directories.
I need the total per directory for all dta files.
