General :: Difference Between Buffered Disk Reads And Cached Reads?

Jul 13, 2011

I was analyzing the Disk read using hdparm utility. This is what i got as a result.

Code:

# hdparm -t /dev/sda

/dev/sda:

Timing buffered disk reads: 108 MB in 3.04 seconds = 35.51 MB/sec

Code:

# hdparm -T /dev/sda

/dev/sda:

Timing cached reads: 3496 MB in 1.99 seconds = 1756.56 MB/sec I m not sure what does Cache read and buffered disk read mean.

Programming :: Bash Script That Reads Lines In While Loop

May 26, 2011

So I need to write a bash script that can read lines and column 3 from a file. It needs to start on line 16 and read every 20th line starting from there. But the value that it reads needs to be checked, should it be too great I need it to shut the program down.I'm pretty new to bash, but my ultimate goal is being able to safely run a program on a GPU for an extended period of time with out worrying about it overheating. I have a command that outputs information from the GPU every second, and I can save this to a file. So all I really need is something to read and check that file, I played around a bit with the awk command and can't get it to work within my for loop with dynamic variable.

Ubuntu :: Write A Bash Script Which Will Find Files Then Move Them To A Specific Directory?

I'm trying to write a bash script which will find files then move them to a specific directory.

So far I have:

Programming :: Bash Script: Sort Files Into Directory Based On Data In The File Name?

Sep 28, 2010

I have very little linux experience. And need some help with a bash script. I need to a script I can set cron to run to sort files out of a holding folder into final folders. It doesn't necessarily have to be bash, but I think it would be sufficient for this. File names are formatted as such when created: Dest-Date-Time-CID-Destination# I want the files to be moved from a all in one holding folder to a folder structure like this.

.../storage/year/month/day/Destination#/VarX(type)/hour/CID/'File'

I would need an if/else if/else statement to say if Dest = A set VarX = B If for example the file name was

infinity-20100927-17:00-1112223333-4445556666.wav

I would like the above file to end up moved from

.../holding

to

.../storage/2010/09/27/4445556666/Inbound/17/1112223333/infinity-20100927-17:00-1112223333-4445556666.wav

So the script will need to make directories based on information in the file name which is delimited by single dashes. Then move files from the holding folder to the newly created "sorted" folders.

General :: Kill Bash Processes "nicely"?

Dec 15, 2010

I'm trying to avoid kill -9 for the reasons described in the Useless Use of Kill -9 form letter. Is this function sufficient, or do I need to kill the kill processes after a timeout or take care of other subtleties?

soft_kill()
{
# Try to avoid forcing a kill
# @param $1: PID
kill $1 || kill -INT $1 || kill -HUP $1 ||
(echo "Could not kill $1" >&2; kill -KILL $1)
}

As an aside, what's a better name for this function? The current name reminds me of "Killing Me Softly", and manslaughter sounds a bit severe. Maybe spoon_kill (Google it)?

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...

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.

General :: Find Directory Older Than X And Mv Directory With Sub Files Command?

Jul 13, 2011

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

Programming :: Bash Scripting - Display Real Name From Username Logged In + User Processes?

this is my script:

echo "Please enter your Username"
read userName
userName= grep $USER /etc/passwd | cut -d: -f5
echo "Welcome " $userName | cat >> output.txt

the problem i have is that when i enter my username, the output (my real name) does not display in the output.txt. instead it displays in putty. so when i run my script in putty it shows the message to enter username and after i enter my username my real name appears below it. i want it to show in the output.txt

General :: Configure The Way Bash Completes Directory Names?

Sep 7, 2011

I'd like to instruct bash to use a special method to perform completion on certain directory names. For example, bash would call a program of mine to perform completion if a path starts with "$$", and perform completion normally otherwise. Is this at all possible? How would you implement it? The goal is to allow autojump to complete paths for all commands when the user starts them with a certain prefix. So for example when copying a file from a far directory, you could type: cp $$patern + <Tab>

and autojump would complete cp /home/user/CompliCatedDireCTOry/long/path/bla/bla and you would just have to add where you want to put the file. Of course I can use ott's comment to add it to a few specific commands

General :: Bash - Finding Newest File In A Directory?

Aug 24, 2010

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.

Ubuntu :: Directory Exists But Bash Says It Doesn't - No Such File Or Directory

Aug 19, 2011

I've run into a problem with my bash program.

Code:a mkdir -p /home/chris/Downloads/ARCHIVE/`date -I` find /home/chris/Downloads* -mtime +14 -exec "cp {} /home/chris/Downloads/ARCHIVE/`date -I` ;

It's meant to move old files from my Downloads folder into an archive file (later tar them). The directory exists, I've used $PWD and nautilus and ls to make sure it's there, yet for every file it gives

Code: find: `cp /home/chris/Download/foo.bar /home/chris/Downloads/ARCHIVE/2011-08-19': No such file or directory I tried to test it on a different destination, specifically my home folder. IT still gave me the error.IS it a bad syntax within find or something else? I'm running a 32-bit system with 11.04
