General :: Get A Shell Script To Loop Through A Number Of Directories And Subdirectories?
Jul 27, 2010I'm looking to get a shell script to loop through a number of directories and subdirectories,looking for files that contain a particular substring, and renaming the file by replacing the search string with a different substring. For example if you had a directory full of folders that contained digital photos (along with various other files which would need to remain unaffected), and the intent was to remove the "DSC_" prefix from several thousand files buried within. I've whipped up a rather long-winded solution that works well for this purpose but chokes on directory names with spaces. I am reasonably sure there's a 2 or 3-liner that would accomplish this exact same task.
function investigate
{
path=$1
for file in `ls $1`
#for file in *

Jan 25, 2011If I only want to let a user be able to login via telnet a max number of times equal to 2 how would I go about doing this?I have found this little tid bit:per_source = 2but that only allows 2 connections from the same source (i.e. network) and that would not work. For some reason our telnet sessions are not dying off after a user has shutdown their PC and then the next time they login it adds another telnet session.

Jun 13, 2010When we are asked for password while booting Linux, is that the login shell ? If yes, we can't seem to be able to do anything in that shell besides typing the password. (Is it in this that the contents of /home/.profile file gets executed ? in a sigle PC)
When we click on the terminal icon for the first time, are we opening a subshell of something or a new shell altogether? If on repeatedly clicking on the terminal icon, new shells are being launched, not sub-shells, then why does export seem to work with the new shells, though its supposed to work for subshells ?

Programming :: Count Number Of CD-ROMs On A System Using Shell Script
Apr 7, 2010I am trying to get the count of number of CD-ROMs attached with my Linux system using a bash shell script. I have decided to use the following method for it:
Code:
debian:~# cat /proc/sys/dev/cdrom/info | grep "drive name:"
drive name: sr0 hdb
So basically I know that there are two CD-ROMs attached to the system. Now there can be three also like this:
Code:
debian:~# cat /proc/sys/dev/cdrom/info | grep "drive name:"
drive name: sr0 sr1 hdb
All I want to do is in my shell script to get the count of the devices in a variable using the above command.

General :: How To Identify A HDD In A Server
Jun 6, 2011Are there any identifiers on an HDD that can be either seen physically on a "sticker" on the HDD, and the same number/identifier could be read with software solutions?
I mean if I see with e.g.: S.M.A.R.T. that an HDD (in RAID) is failing, then I give out the command:
SOMEMAGIC
then I get an OUTPUT, e.g.: 9835923759237489
and then are ther any stickers on the HDD that has a label: 9835923759237489 ? so the hdd that has to be changed could be identified.
