Programming :: Bash Script To Check How Much Free Space Is Left In /var Directory
Feb 24, 2011
I'm creating a bash script to check how much free space is left in /var directory then, if it hits a certain threshold, delete certain files with numbers for extensions (e.g. fileA.1, fileA.2 fileA.3, and fileA.4, fileB.1, fileB.2 fileB.3, and fileB.4 ). Here's a snippet from my script:
[Code]...
If I use a * as a wildcard for the number extension, the script fails. Maybe regex would work here, but I'm not particularly accomplished at it. Or some other construct.
i'm using c++ and Ubuntu and I need to write/copy some files to a directory chosen by the user of my system (the user can save it on any folder of any disk of the pc or other usb device). Before I do it, I need to know if there's space available on the disk. I cannot only check the result of write() function, the validation must be executed before I start to save or copy.
I was trying to use statvsf structure, but I only have the complete filepath (/home/lobinho/myDocs/), not the disk path. The statvfs() function only works with disk path (i.e. /media/KINGSTON ).
The source of my function:
Code: int MyClass::availableSpace(string dst, ulong* availableSize) { int result = ERROR; try { struct statvfs devData;
I have been searching for 90 minutes for something that I "think" should be fairly easy. I'm pretty new to Bash Scripting so I could be completely wrong. Then again it may be a weird request to even need something like this. But here it is.I have a script written to convert data from one of our software version to another. The only thing I need to add to it is a "check to make sure the user running the script is in the /tmp directory".
I'm running CentOS 5.2,on a 64-bit x86_64 Linux machine with kernel version 2.6.18-128.el5 smp. I appear to have version 2.9.4 of xfsprogs. I have a 22TB xfs filesystem ,Yesterday, the hard disk is full, today released a 7.7T disk space.But still can not write to new file. software ambience:
[root@Production data5]# uname -a Linux Production 2.6.18-128.el5 #1 SMP Wed Jan 21 10:41:14 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
I'm using a large xfs partition on a large raid volume using 7 1TB drives. I am currently getting a "no space left on device" error message when creating files or directories. However I see the following output when checking space limitations.
Command "sudo aptitude install oxygen-icon-theme" return following error:
dpkg: error processing /var/cache/apt/archives/oxygen-icon-theme_4%3a4.6.2-2_all.deb (--unpack): unable to install new version of `/usr/share/icons/oxygen/22x22/apps/preferences-desktop-default-applications.png': No space left on device
[Code]....
As far as I can see oxygen-icon-theme unpacks only in /usr/share, beyond it I can think of only /tmp, /var or /var/tmp that it may use, all of which have plenty more than those ~40 MiB that it supposed to occupy unpacked. All btrfs filesystems were formatted with "-d single -m single". System is Debian Sid 64-bit with linux-image-3.0.0-rc5-amd64.
I can't seem to find anywhere to find how much free space i have on my "my book world edition II", Unlike normal HDD's when you just right click and it shows the Yellow and blue circle.

I have searched google for a couple of days, and I keep hearing about an INode limit on filesystems, but that doesn't seem to be the case.
Now whenever I try to download something, watch a ..... video, or listen to Pandora radio, it just stops playing after 2 seconds. Downloading says "No space left on device".I also get the error as root.I do have 5% and more free of HDD space. After reading the similar posts I checked all of this, so if I am overlooking something on the forum, I apologize for an extra post about.
I have 160gb laptop. i installed vista in c primary partition which is 25gb and installed ubuntu in d primary partition which is 20gb. A remainig for my data. Now i tried to install CENT OS by formatting ubuntu. I inserted CENT OS DVD and restarted and i selected to delete my /dev/sda2 which is showing 20480mb and it shown me free space. but i tried to add partion /boot of 100mb it got added. but, when i am trying to add / of 3000mb in the remaining 20380mb free space it showing an error message that no free space is available.
i tried to create a if else statements or either an else statement I get a message saying that the directory exists (mkdir: cannot create directory `./MAY2010': File exists I am running this in a crontab file and I dont want any output telling me that the directory exists. I just want to check if the directory doesnt exist, create one else do nothing (not even a message telling me that the directory exists).
I have a file with one line. I want to check whether the first character is TAB or space, how can i do this.? using "cut" wont as it "bypasses the tab and space characters"
I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.
I'm having trouble trying to make a script. What I want to do is check if xScreenSaver is running in my user account. If not, run it. If it's running, kill it.
So this is the script I've made:
Code:
The problem is that I've echoed the output of $(pgrep -u $(whoami) xscreensaver) and it always seems to add 4 numbers to the pid, even if the pid doesn't exist. What do I mean by "doesn't exist"? That no xscreensaver is running in my user, and if I run pgrep -u $(whoami) xscreensaver in bash, I get not output, but if I run the command though the script, I get (for instance) 4050. If I run it again, I get 4054, and again 4058... etc. What the hell is going on with that?
Today I was installing a lot of software since I'm just setting up my Slackware system again after a fresh install, and I realized that my root partition has very little space left.
Here is the output of df -h:
Code:
As you can see, I have a 20G (19G here for some reason) root partition, 8G /var, and 86G of /home. I thought this would be plenty since many recent recommendations for / are 10-15G. Now, though, 17G are used up for some reason! How is this possible? I thought a full slackware install only had about 4G of software! I don't have any music or movies or any crazy huge files that I know of, and those would be in my /home directory anyway. Is there any way I can see which files are taking up all this space?
If it's necessary to allocate more space to my / partition, is it still possible to boot up a GParted live Cd, shrink /home a bit, move some partitions to the right, and expand my root partition? I would REALLY prefer I don't have to reinstall since I just spent a ton of time setting up my system again, but if worst comes to worst ... :'-(
As part of my script I need to compress a 50Gb file. but I need to check that the compressed is not corrupt if it is ok it will then send it over if not it will report an error.
cd /home/ops/Desktop/temp tar czvf backup-"$(date +%d-%b-%y)".tgz /home/ops/Desktop/temp
I need some here to check the compress file then somelike if the file is
if send the file else send an e-mail reporting a failure
I am looking for a little help with a Bash Script. I have just finished a PC GUI application using Pygtk and glade. But, I would like to write a Bash Script to check if the user has the needed software to run my application on his or her computer. For example, the software needed to run my application among others are Python, nmap, and pygtk. Code: which python which nmap With a little bit of research I found:If python or nmap are installed on my computer and I run the above commands, the above code will tell me where it is located. But if python and nmap are not installed and I run the commands, nothing is displayed.
Could I get a few ideas on how I would go about getting a boolean value to determine whether or not the software is installed or not. I would like to use the boolean value in my bash script to perform other actions ie echo "Python is not installed" or actually install Python if the boolean value is false.
This script that I found online does the job it promises. it does convert the files to mp3 without an issue. What I need to include now is an if statement that says If $file.mp3 exists then delete $file.wav
Code: #!/bin/sh # name of this script: wav2mp3.sh # wav to mp3 # Credit to the script creator (Nikesh Jauhari):
[Code]...
After that I'm stumped as to how to do the if statement
I was trying to install Fedora 13, on to my laptop. I have 30 GB of unallocated space in extended partition. When trying to install Fedora 13, I got stuck, as the installer says that there is no free space for installation.can convert the unallocated space into free space.
i used gddrescure to clone an 80gb harddrive and this is the result ROFL.i guess you can only do this making sure the target drive is the same size, you see i didnt know lol so..i now have THIS problem.can anyone tell me how to turn my unallocated space into a usable 'free' space? i could play with gparted right now but i dont wanna do anything wrong, so if theres anyone who can tell me how to do this.
I have red hat linux server and it has mysql installed whenever i write on terminal command mysql -u root it shows error "ERROR 2002 (HY000): can't connect to local MYSQL server through '/var/lib/mysql/mysql.sock (111) "
And another problem is that it is showing 0 byte free space istaed of freeing the space. it may seems that both problems are dependent on each other.
I have a directory called /data In this directory I have some files like abcejb.jar,12_ab_ejb.jar, shejb.jar, test I need a shell script like... 1st I want to check if there is any ejb file exists in the directory using some condition If ejb files exists I want to redirect the ejb files list to a file called list. Now I want to copy all the files in the list file to some remote system.
i made space by shrinking my window partition and so i have unallocated and would like to add to sda2 to have more space. Check out this pic. How can i do this?
I am trying to write some small script file that will check if a USB stick is connected to my pc or not. I can't seem to get it to work, but I am sure it is a very simple fix.
I am running on Fedora core 10.Can anyone help me figure out what the problem is?If I run these lines through console it works fine (meaning, I type the commands in this file straight in the command line/console).
