I'm the POC for all my families Linux computers. Is it possible to get statistics on which programs are accessed, how frequently, for how long and by which user?
When it comes time to upgrade it would be useful so I know which programs to concentrate my testing. I usually just e-mail and ask but every time people forget to send me the programs they actually use.
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.
I need to organise an external HDD such that there is no more than 500 folders on it.
Ubuntu's "Properties" pane shows only the file count, not the folder count.
Is there a simple CLI line that will tell me the number of subdirectories?
i try to make a script in bash that u choose a number for example 501 and another number like 1 and find how much the 1 number repeat in all numbers from 1 to 501 for example 11 -->1 repeat 2 times.in 1 to 501 the number 1 repeat 200 times.

And I'm trying to count the number of slashes in each line. I figured (with my limited knowledge of bash) that the best thing to use would be sed. So I ran this to print "not /": sed '!s////g' file # and eventually adding " | wc -m" to it. and I got the same result as if I ran cat, no modification at all:

View 2 Replies View RelatedI recently found myself in possession of a large file (a few million lines in length) of short strings and would like to count the number of lines that are unique to the file. I thought this would be an easy process, but while working on the problem, I encountered the following. Can anyone explain this weird result to me?

I'm trying to find a script that will return me the largest number of repeating characters. Say, I have the following line in a text file: 12345AAAAA6789AAA
I want it to return 5, because "A" is repeated 5 times in this line (more than 3 at the end).
I am using grub of version 2, and current resolution vga=795 (probably). X runs at 1680x1050. So what I would like to know is, how can I count the right VGA parameter number for grub, to use another resolution?

I have been able to use find -type d to list directories and subdirs but I want a numerical value of dirs and subdirs. I know ls -l gives a count but when I try ls -l -d all it shows is "." I also have tried a combination with the -R option but nothing seems to be working for me.Please forgive my ignorance but I am working on a script for class and this is the first step.

I recently setup a new Linux server running Fedora 10. For some reason all ping response times are rounded to the nearest 10ms. For example, running the simple command "ping yahoo.com" give the following sample results:
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=12 ttl=57 time=60.0 ms
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=13 ttl=56 time=50.0 ms
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=14 ttl=56 time=40.0 ms
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=15 ttl=56 time=50.0 ms
I could post a larger result set but its all the same... every response is rounded to a multiple of 10ms. This wouldn't be a big deal except that the server is running Nagios for monitoring so accurate stats are important. The Nagios check_ping and check_icmp commands are also returning rounded off results. How can I get ping to simply respond with the actual response times rather than a rounded off number?
I'm trying to write a bash script with a for loop that will perform two tasks a number of times depending on the number the user enters at the start. Here is what I got so far. It works fine the first time but then it just exits with no error msgs. The problem is in the way I have written the loop command. I have searched the web for examples to find out what I'm doing wrong with no luck.

View 8 Replies View RelatedI recently installed ubuntu 10.10 and am completely new to linux. Something I recently noticed is that my whole system will freeze 2 times after logging back in, but after that it works fine. I will log in, then it will work fine, but shortly after it will completely freeze. After about a minute, it will unfreeze and everything will work fine. Then after a little longer, the exact same thing will occur. After the second freeze and unfreeze, it never occurs again until I log out and log back in. I do not believe this occurs when first starting the computer.
