General :: Get A Shell Script To Loop Through A Number Of Directories And Subdirectories?

Jul 27, 2010

I'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 *

General :: Let A User Be Able To Login Via Telnet A Max Number Of Times Equal To 2?

Jan 25, 2011

If 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.

1. user1 31300 /dev/pts/409
2. user1 27539 /dev/pts/539
3. user1 18042 /dev/pts/316

I work with a text mode debian6.0 and when I was testing some commands, I changed default shell to ash. System replied that it has not ash shell.so I thought the shell did not change. But when I start the system again and enter root password, I see a message like "can not execute ash. No such file or directory" and then system return to login page again. Root is the only user on that system.

General :: Login Shell And Consequent Subshells

Jun 13, 2010

When 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, 2010

I 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, 2011

Are 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.

General :: How To Identify Current CPU In A Parallel Machine

Sep 1, 2010

I do not know much about parallel computing, but I do have access to a few cpus.I am trying to write a program compatible for multiple cpus, but to do it, I need to ensure unique directories. I have figured out that the time of creation, process id, and cpu id form a unique combination I can use to name files (up to the degree of accuracy of the internal timer).Anyway, I am using perl. I know how to find the process id and I know I can get the time pretty easily, but as I said, I do not know much about hardware or parallel computing. All I need is a way to identify each cpu in the system and I am set for half of my program (the other half is significantly more straightforward and is mainly about text parsing.)

So anyway using terminal, perl, etc., I could access this identification? Or could someone at least tell me the name of what I am looking for? I have seen the words "ip" "MAC" "hostid" and a bunch of other "id" things come up in my googling, but I really cannot figure out which is the one relevent to me
