I want get the information from a directory full of files.
What I have so far is this:
Code:
find <path> -exec head {} ; | tail -2
My question is, how do I get that certain section from each file, since tail will only affect the last file. I've tried piping head and tail to sh but that's not available due to permissions.
I have a file that I am attempting to use to restore a website for a client. The file is a drupal folder structure where all of the files in the folder (3000+) have been individually compressed into 3000+ individual gz files.
I have figured out how to uncompress all the files using WinRAR but it puts all the files into a single directory, i need the original folder structure maintained.
The default Emacs on Mac OS X, 22.1, appears to have some problems with the info/help stuff.
When you hit C+h i, it says:
Can't find the Info directory node.
It works in AquaEmacs, but I downloaded the 23 version of emacs precompiled binaries from here and I still have the same problem.
I need to write a script to report useful information on disk utilization for each user's home directory.For each directory I need to show: 1. the long listing of that directory entry (but not the files in the directory), so that I can see the rights and owners of the directory.2. The amount of disk used by that directory, in human-readable format, including subdirectories. I need to have two lines for each user one after the other. For example:
/home/user1 directory info
/home/user1 disk usage
/home/user2 directory info
/home/user2 disk usage
The script will assume that all users, except user root, have their home directories in the /home directory (no need to do anything with the /etc/passwd file). And if the administrator adds or removes users, the script should still work correctly (so the script shows the information for all current users).
Here's what I do know. The command "ls -ld /home/user's_name" will give me the info I need for #1. And the command "du -hs" will give me the info I need for #2. What I don't know is how to grab each individual directory in order to apply the above commands to each of them in order. ???
I am currently interning at a place and my job is to essentially learn UNIX. My supervisor gives me problems here and there to help guide me with my learning but for the most part I'm doing this all by self-teaching myself. Needless to say I have run into a few obstacles...for instance-Create a *one* line command that, using tar, will collect the full /usr/local directory (you need to run this as root again) and copy the whole /usr/local structure under /optFor example /usr/local/bin/hello will become /opt/local/bin/hello, etc. I want this as follows:1. /usr/local is collected by tar, but the output of this tar command is its stdout.. what you get from the previous stdout, you compress with gzip and send it to stdout again 3. get this output and decompress with gzip.. get this output and pipe to tar in a way that will extract the tree under /opt.If anyone knows how I could go about doing this, please let me know, or at the very least point me in the right direction. What I've got so far (which could be completely wrong) is:tar cvf - usr/local/ | gzip -c - | gunzip -c - | tar xvf -in theory I feel like this should work (except for extracting the tree under /opt...i'm kinda stuck there)

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

View 1 Replies View RelatedI 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.
