My script is not diaplying output as it contains awk while iterating over the array. My script is as follows:
shortcodes=( "56882" "58585" "58888" "57575" "57677" );
for shortcode in ${shortcodes[@]}
do
echo "`awk -F"|" '/ShortCode=tel:$shortcode/ { arr[substr($2,1,4)]++ } END { for( no in arr) { print no , arr[no] } }'
[code]....
Take this block of pseudocode:
Code:
for i in $list; do
<some statements>
if i > 5
exit
<more statements>
done
That is, want to terminate the iteration just after 5 iterations. A first problem, is that list is a string and not a number. It's all I can say, except to keep reading bash monster manual.
I am trying to use awk command in perl. Below is my awk comamnd which works alone.
awk '{Easttot=Easttot+$1} END {print Easttot}' MessagesProcessedEAST2Cnts.dat
I would like to use this awk's output in shell script. I am using system command like below to get the out put. But it is not working.
$Output = system("awk '{Easttot=Easttot+$1} END {print Easttot}' MessagesProcessedEAST2Cnts.dat'");
I use 'grep -Ri "mypattern" .' to search for all files in the current directory recursively that contain "mypattern". But this command returns every single occurence, so that if a given file has several occurences of the pattern, the screen fills up pretty quick. More than likely, there's a way to restrict the output so that it only displays each file once, no matter how many occurences it contains, but I couldn't find how to do it.

View 6 Replies View RelatedMy first post and only my second day using Linux (Ubuntu 10.10), so please be gentle with me. lol. Bit of back ground to my problem. I have a Netgear Stora that has just died, but realy need the info off the drive inside. Support have told me that the drive can be read on Linux, so here I am. Right. Places-Computer shows drive as "array". System-Administrator-Disk utility gives me everything blank apart from State : not running, not enough componets to start. Now there is a button under this "Start Array". Can I simply just click this or is there more to it than that as I don't want to lose anything on the drive.
View 8 Replies View RelatedConsider a situation in which you want to display only specific lines of contents from a file or of a command's output. Yes, we have head and tail commands. But, how to view all the lines of a file except the last one or vise versa when we don't know the count of lines in advance?
Consider this output:
Code:
[root@localhost ~]# ps au | grep bash
root 6316 0.0 0.0 4672 1440 tty1 Ss+ Apr22 0:02 -bash
root 20847 0.2 0.0 4672 1432 pts/0 Ss Apr23 0:12 -bash
root 21167 0.0 0.0 3920 660 pts/0 S+ 01:00 0:00 grep bash
Here, I don't want the last line (in italic) to be included in the result since the last line is due to "grep bash" in the devised command "ps au | grep bash". Well, we can rewrite the devised command:
Quote:
"ps au | grep bash | head -n 2"
But, again, here we are specifying the count of lines to be included. But, in the presented problem we don't know any count in advance!
The video projector I have to use this week projects an image too large for its screen and spills over on every side.
Fixing the physical setup is not possible or at least unlikely for the moment: the only solution is to carefully resize and position windows so that they display in the visible part of the screen - using full-screen mode is out.
Is there a way around this via software, using xrandr for example?
# xrandr doesn't have a padding option...xrandr --output VGA1 --mode 1360x768 --left-of LVDS1 --padding 200

1st I am relatively new to linux (but not to *nix). I have 4 disks assembled in the following intel ahci bios fake raid arrays:
2x320GB RAID1 - used for operating systems md126
2x1TB RAID1 - used for data md125
I have used the raid of size 320GB to install my operating system and the second raid I didn't even select during the installation of Fedora 14. After successful partitioning and installation of Fedora, I tried to make the second array available, it was possible to make it visible in linux with mdadm --assembe --scan , after that I created one maximum size partition and 1 maximum size ext4 filesystem in it. Mounted, and used it. After restart - a few I/O errors during boot regarding md125 + inability to mount the filesystem on it and dropped into repair shell. I commented the filesystem in fstab and it booted. To my surprise, the array was marked as "auto read only":

and the partition in it was not available as device special file in /dev:

I work in a simulations environment. I'm trying to write a bash script that will read fields from a .csv file into an array, the first field being an identifiyng number and the second field being a corresponding url. There are about 1600 of these number/url combinations in the .csv file that i'm reading from. Once that is done i want it to parse a text file and match the number, when it has a match i want it to enter the corresponding url into a particular line in the text file. The script I have written (with the help of the people on this forum a while back) does this well, but now I have a lot more data to parse. I think the script itself is explanatory enough to see what i'm doing. What i would like to do is cut it down to one while loop nested inside another loop so that I don't have 1600 or so elif statements. I can't figure out how to increment the output of the array. for instance, the first cycle would find the number that matches ${record1[2]} and input the url stored in ${record1[3]}. the next cycle would match ${record1[4]} and input the url in ${record1[5]}, and so on, does that make sense? The code is below and a sample .csv and text file are attached.

I have a command that outputs n lines of text, and I want to place each line into an array element, but I can't seem to get the syntax correct
So my command is this:
cat $configfile | sed -n '/cluster:'$clustername'/,/cluster/ p' | awk /host/
Which produces many lines depending on the value of $clustername. I'd like to get each line as elements of an array.
I have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care).
Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?
I have an array called arrayini which stores numbers. I want to take log to the base 2 of each of the numbers in that array and put it in file called result. I've used the following code to do it.
Code:
size=${#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 m running a command
Code:
watch -n 1 -d netstat -i
to see the packet drops every 1 second. but the problem is the output is so long(Due to large number of virtual interfaces) it doesn't fit into the putty prompt. I dont need to monitor each and every network interface I m more interested in monitoring the interfaces starting from vif but whenever i run following command it doesnt display anything.
Code:
watch -n 3 -d netstat -i | grep vif*
What should i do?
I have a python script that when run outputs to screen.
eg.

sms successfully delivered from 61403000511 to 919227434827
But when I try:./international_sms_check.py 0403000511 919227434827 > test
The file test is created but there is nothing in it.if I try ls > test this works fine with output of ls redirected to file test.
One of my servers needs to issue an "apt-get update" command on each of the clients in a lab. However, after the first update, it exits. In trying to replicate the problem with a simpler script, I created the following which fetches the listings of multiple directories from a client:
NUM=0
cat paths | while read DIR; do
ssh server-name ls $DIR > /tmp/$NUM.txt
NUM=`expr $NUM + 1`
done
Again, after the first iteration, the script exists. I tried the following line too, but it made no difference:
bash -c ssh server-name ls $DIR > /tmp/$NUM.txt
The only thing that worked so far is this
xterm -e ssh server-name ls $DIR > /tmp/$NUM.txt
