General :: Pass Wildcard Array To Cp
Sep 12, 2011
passing a wild card array to cp, I know it can be done but cant figure it out, ive got 3 files all start with the word somefile but have 3 different extensions
somefile.conf
somefile.dat
somefile.py
there in a folder with a bunch of other files and I just want to copy them to a different location. I remember is being something like cp somefile.[py conf dat] /somewhere but this isn't working Ive searched the net and can't find it with the keywords i'm using.

Can I dereference a wildcard in a command?For example if I want to create a file with the md5 hashes of compressed versions of files in a directory...gzip -rc ./source/* | md5sum -b - >> hash.txtThis above command gives me a file with one hash for the filename *I would like to get a file with the hashes and filenames for every file gzip compresses.

I would like help with modifying the following content:
toolbox/perl/man/man3/ExtUtils::Command.3::Command.3 differ
toolbox/perl/man/man3/ExtUtils::Command::MM.3::Command::MM.3 differ
I would like the content to be changed to:
toolbox/perl/man/man3/ExtUtils::Command.3
toolbox/perl/man/man3/ExtUtils::Command::MM.3
I was not sure how to tell sed what to look for? I tried the following but it did not work. sed -i 's/::* differ//g' mandiff.log

I need a command to search for any file in a directory like so:
/home/*/upload/* and then change permissions any file in that directory.
Find doesn't seem to match what I need.

I have 2 massive duplicate dirs of the same format as below:
dir1
subdir1
file1
subdir2
file1
subdir3
file1
...
Dir2 is the same, but it has some newer files of the same name. I want to copy all file1's from Dir2 to the same name and folders in dir1. So basically something like:
cp -pr bkpDir1/*/*-big.gif Dir2/*/*-big.gif
This works for singular cases:
cp -pr bkpDir1/uniquesubdir/*-big.gif Dir2/uniquesubdir/*-big.gif
But not for wildcards:
cp -pr bkpDir1/subdir*/*-big.gif Dir2/subdir*/*-big.gif
Anyway the aim is to do the first cp above, I have tried a few options using find. In trying to show an example stumbled upon a way that worked, while in dir2:
find */*-big.gif | xargs -i cp -rp {} ../dir1/{}
Sure there are better ways also...

I have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care).
Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?

I have an array called arrayini which stores numbers. I want to take log to the base 2 of each of the numbers in that array and put it in file called result. I've used the following code to do it.
Code:
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
echo "scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >result
It works fine but its taking pretty long to calculate since I've got about 230,000 items in the array. So I decided to store the result into an array hoping that it'd be faster. I tried the following code. arrayresult is where I try and store the result. The code doesn't work because of the second last line.
Code:
unset arrayresult
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
arrayresult[$i]="scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >FILE2
There is a syntax error clearly.

I have some mp3 files with the wrong date stamp on them. I need to change the month value to May, and the Day needs to be changed from 6 to 4. For some reason my mp3 recorder messed the datestamps up. The time part is fine. I have changed the first three files to the correct MMDD parts, using the following touch command:
Code:
[root@karsites 04-may]# touch -t 05040253 REC066.MP3
[root@karsites 04-may]# ls -l REC066*

if I've missed this in the doc's, but I don't see the ability to "wildcard" blacklist for packages to _not_ be changed out via the slackpkg program.More specifically, I tagged all my packages like this:
mozilla-firefox-3.6b4-i486-1_OLDFOGIE.tgz
note the "OLDFOGIE" in my package name? So can something such as:
Quote:
*OLDFOGIE*
be put into slackpkg blacklist file?

Out of the box, Bash in 10.04 is configured such that it won't expand/complete parameters when there's a single match for a parameter with a leading wildcard. For example, if I have the following files in a directory:
Code:
ABC.bin
DEF.bin
GHI.bin
...and I type cp *E*, I expect to be able to press TAB and have Bash expand *E* to DEF.bin, since that's the only file in the directory with a capital E in its name.
(Note: if I actually submit the command with the wildcards in place, the correct file will be used then, but I don't get to see it beforehand.) I imagine there's something in /etc/bash_completion that's preventing this from working properly. Does anyone know what it is?

I'm using Apache 2.2 to host multiple subdomains using a single SSL certificate (a wildcard certificate e.g. *.mydomain.com) and, yes, it works! Everything seems to be served correctly and the browsers are pretty happy.
And you can also have the non-SSL sites (virtual hosts on port 80) on the same IP. (That's covered elsewhere)
For those that want similar functionality here's my discovery...
My configuration is like this:
ssl.conf:
Code:
I would have to say that I don't believe that this will work if you are not using a wildcard SSL certificate and having anything other than subdomains under that wildcard.
It is somewhat limited in scenario where this is useful, but for a set of company websites that should be under SSL, this can be tremedously useful when you have a single IP.

I have a NETGEAR ReadyNAS NV+ with four 1TB drives in a RAID-5 array. This is our primary file storage. This has previously been backed up to a hardware RAID-0 array directly attached to our Windows server. The capacity of this backup array is no longer sufficient. So the plan was, take a bunch of 200GB to 320GB drives (And a 750) I had kicking around, chuck them in a couple of old SCSI drive enclosures I have collecting dust, attach them via IDA/SATA-to-USB adaptors to a USB hub, attach that to the server, create a JBOD array spanning the disks, and back up the NAS to that. Performance is not an issue as this is just to be used for backup, with the idea being as near to zero cost as possible (Spend so far = NZ$100�ish).
The first hurdle I struck was Windows not supporting Dynamic Disks on USB drives (Required to create a spanned volume). At first I resisted using another machine (i.e. a machine running Ubuntu) as I didn't want to dedicate a piece of hardware to backing up the NAS. I then decided it would be acceptable to do this via a VM, which is what I've done.So I have 10.04 running under VMWare Server 2.0.2 under Windows Server 2008 R2. The disks are all presented to the VM. I wasn't sure if I was going to end up creating the array under LVM or something else, but I noticed Disk Utility has an option to create an array, so I tried that. When I add two 250GB drives, the array size is 500GB. When I then add a 160GB drive, the array size drops to 480GB. Huh? If I keep adding disks (Regardless of order) the final array size comes out at 1.8 TB, as per the attached screenshot. Now with the following drives, I expected something more like:
160 + 250 + 250+ 750 + 250 +200 + 200 + 250 + 320 + 250 + 320 = 3.2TB
Am I missing something or making a false assumption somewhere?

I've got a sticky little problem with a bash script. Please consider the following code:
Code:
#! /bin/bash
processArgs() {
echo "Count = $#"
while [[ $# -ne 0 ]]; do
echo $1
shift
done
}
processArgs $* If I call this script with Code: ./script first second third it'll print each of the argument on a new line - exactly what I would expect. However if I call it with
Code: ./script "Single Argument" "Second-Argument" it splits the first argument in two using the space as a delimitor. The problem appears to be the call to processArgs, where $* doesn't honour the quotes around the variables sent to the script.

I want to pass a variable from one script to another, I have a feeling it's extremely simple.
I looked at exporting, but apparently that clogs up the shell, so I don't want to go down that route. Any suggestions?

I'm writing a PHP program. I've encountered a problem; in the following code I try to pass $_POST['delete'] which is an array as the value of a hidden input to some form, but it doesn't do so.there's something wrong with converting PHP array into HTML array. I'm sure that $_POST['delete'] is not null and is a real array.
echo '<input type="hidden" name="delete[]" value="'.$_POST['delete'].'" />';

What i want to do is create multiple informix sql statements & later run them via a bash script.
Here is what i have so far (this works) but is meant to be run from a cron job so it only does one day at a time:
echo "
update hst`date --date='yesterday' +%m%d%y`
set x = 'GARP'
where y in ('CRE', 'LAC', 'SRL', 'JAG', 'JNM', 'BIM')
and appl = '';
[Code].....
The problem here is it doesnt want to read the variable $x correctly so the statement fails.

I have a backup schedule running a full backup everyday. I'm using webmin to manage these backup now. The problem is when the dump command sends a prompt asking if we want to rewrite the tape, Webmin does not display this prompt and we end up having to terminate the backup -> erase the tape(which takes a long time) and then run the backup again.I was wondering if there is a technique that could be used to pass "Yes" as a parameter to the dump command, much like in windows? or if there is a more efficient way of getting this done.
