we have centos and a win2k8 server. Our pos system is on the centos server. I created a HOST (A) record on win2k8. so users don't have to remember the ip address of the centos server.so i created a friendly name like URL... and the POS web page will be loaded.but my questions is it possible to configure the centos to automatically append the port number if the user type URL... will be auto added at the end of it.

How can I read .gz file direct on shell/terminal without decompressing the file?

I have a file which has several entries with
# comment 1
1245
# comment 2
5667
# comment 3
456456
how can I read the file, sum the numbers ( "avoid" the #lines) and then get the average of the numbers?
I do awk '{s+=$0} END {print s}' /tmp/file.txt. and this give me the sum correctly, but how can I get also the average ?
algorithm:breada
input: file system block number for immediate read
file system block number for asynchronous read
output:buffer containing data for immediate read {
if(first block not in cache) {
get buffer for first block
if(buffer data not valid)
initiate disk read }
if(second block not in cache) {
get buffer for second block)
if(buffer data valid) //line 1
release buffer else
initiate disk read //line 2 }
if(first block was originally in cache) //line 3 {
read first block
return buffer }
sleep (event first buffer contains valid data)
return buffer }
Here is an algorithm for block read algorithm. I have problem in
line 1: If buffer data is valid why is it releasing the buffer?
line 2: If buffer data valid why is it initiating disk read. It should have read directly from buffer?
line 3: It should be the first condition as if it is there in cache then it should return it without delay?
if there's a tab-delimited file under /usr/desktop, how can I determine the number of rows and columns of the file in shell?And, if told the the 3rd column of the file contains only numerical values and all values in the 5th column are unique, how can I verify these in shell?

View 8 Replies View RelatedI'm looking for a way to insert the number of lines in a file to the start of the aformentioned file. This should be simple but as I am not used to scripts in Linux, I am finding it tough going. I can find the number of lines in a file easily enough via
filesize=$(awk 'END {print NR}' $1)
but as for inserting this into the first line, i'm failing to do so. I've tried some of the other approaches on these forums but none so far have been able to do so.
I've tried:
sed '1i$filesize' $1
but sed i requires a string, not a variable so no go I've also tried:
mv "$1" "${1}.bak" 2>/dev/null || touch "${1}.bak"
cat $filesize "${1}.bak" >"$1"
but again with no luck as cat seems to need an input stream Just to recap, i want to insert a line at the start of a given file that holds the number of lines the original file has.
ie the file:
a
b
c
d
e
should become:
5
a
b
c

View 2 Replies View RelatedI want to append some text to the file, files are mostly big, more then 100 mb. I found the cat command, so I can create a new txt file and then append it to the original file with it. Two questions:
1. Can I append text to the file instead of creating the new file and then appending it to the original file? eg:
Code:
cat file.avi "some text" > newfile.avi
2. cat takes several seconds to execute the merging files together, it seems that it is reading the original file first, is there a way skip the reading and just append the file?

How do you append text to an entry in an existing file? For example, lets say I have a file called "env.logon" in /home/myself/bin that contains the following text:
PATH=/bin:/sbin If I wanted to add, via command line, ":/usr/bin:/usr/sbin" to the PATH= and I
used the "echo" command (echo "PATH=:/usr/bin:/usr/sbin) it would create a second entry and my file would look like:
PATH=/bin:/sbin
PATH=:/usr/bin:/usr/sbin
What I want is for it to look like:
PATH=/bin:/sbin:/usr/bin:/usr/sbin
Is there a way to get this result via command line?
I am thinking of appending something to each line in a text file with Java. I prefer not write a new file with content appended from the old one.That 'something' would probably be Time Stamp when the file is created (which is same for each line).I am not sure Java provide some easy way for it or not

I plugged in my USb drive into my computer yesterday and tried to delete a folder. I was unable to do so and got the following message
Cannot move file to trash, do you want to delete immediately? The file "my file" cannot be moved to the trash. Show Details Unable to create trashing info file: Read-only file system
So when I click on delete I get another error message:
Error while deleting.
There was an error deleting Case Study Database. Show Details Error removing file: Read-only file system
At this point I can only click on Skip, Skip All, or Cancel.
I have not changed anything on the stick recently so I dont know what is causing the problem.
