I have a file (called twitterstatus.tmp) that looks like this:
Code:
<status>
<id>24854489768</id>
<text>Are we gonna ride the sun home?</text>
<id>55266987</id>
[code].....
How could I feed this into an array, with each element containing everything between the <status> </status> tags?
PI'm trying to write a script to list all open ports in the MINIUNPND chain in iptables and use the procotol, port and destination ip to open ports on another router using upnpc.Here is the output of iptables -L MINIUPNPD
Code:
>iptables -L MINIUPNPD
Chain MINIUPNPD (1 references)
target prot opt source destination
ACCEPT tcp -- anywhere 192.168.3.124 tcp dpt:19955
ACCEPT tcp -- anywhere 192.168.3.124 tcp dpt:20054
ACCEPT tcp -- anywhere 192.168.3.130 udp dpt:10654
ACCEPT tcp -- anywhere 192.168.3.121 tcp dpt:29955
code....
No matter what i do i cant seem to remove the first 4 characters from the MYPROT array to leave only the digits. Also i cant seem to read the array back???
I thought it would simply be a loop reading each line and passing the fields in variables, executing upnpc commands i need then moving to the next line of the file until it reached the EOF.
I have a large text file with three columns. I'm trying to write a PERL script that splits the file up based on the value of the 3rd column. So every time the third column reads 0, a new file is created and all the data up until the next 0 is found is written to that new file. This should happen over and over until the initial file has been entirely split up.
ex data:
000
2024
2243
2143
96962871
97972878
000
2034
3034
3352
So with the data above, the file would be split into two files:
data_1.txt would contain
000
2024
2243
2143
96962871
97972878
and data_2.txt would contain
230
2034
3034
3352

I want to list the contents of a zip file amd put each entry into an array. I've been doing
[code]....
I am trying to do this:
1. Read csv delimited file line1 and store all values in array
2. Use the values stored in the array and replace values in other text file with them
3. read line2 in the cvs file and repeat the process
4. Do above for all lines in the cvs file
for example:
file1.cvs content:
text1,text2,text3,"text 4"
a1,a2,3,"a 4"
file.txt content:
some text $array1$ some text
some text $array2$ some text
1. read line 1 - text1,text2,text3,"text 4" put each value in array X[] lines that contain spaces in cvs will have double quotes
2. read x[1] and replace value $array1$ (in file.txt) with x[1]read x[2] and replace value $array2$ (in file.txt) with x[2] and so on
Can above be accomplished in BASH and how?

I have an array called @logons. How can I step thru the array and split the fields? This is what I have so far, but doesnt work. I got the feeling I the split statement syntax is incorrect.
Code:
print @logons;
foreach my $logons(@logons){
($userid, $ip) = split(',',$logons);
[code]....
Update: Appears the data in @logons has a column header from the mysql query which I used to populate it with. So that code which I was testing does indeed work.

At the moment I got my md5sum checking working which I write to a text file and see below.
If the md5sum works it will write the output to check2.md5 test.txt: OK
If the md5sum fails it will write test.txt: FAILED
How do I write if statement to check the output whether or not the md5sum failed or not ?
check1="/home/ops/Desktop/test1/check1.md5"
check2="/home/ops/Desktop/test1/check2.md5"

write such script (bash script). I have some text file with name filename.txt I must check if this file contains string "test-string-first", I must cut from this file string which follows string "keyword-string:" and till first white-space and save it to some variable.

700
800
900
1000
1100

Person B
1200
1100
1000
900
800
700
600
500
400
300

How would I go about reading the values for each Person, then being able to perform mathematical equations for each Person (finding the sum for example)?
I have a script which checks on my jobs that run on some cluster.The script, "script.sh", takes as an input the job-id for the job to be checked. Sometimes I have 100s of jobs and I want to check them all (for successful completion.) I could put these job-ids into a text file, "job-id.txt", each id in its own line.For each job-id, the script would ask me few questions (with a yes or no answers) to see if I want to do some other checks for each job-id.I want to know how may I direct my job-ids from this text file into the script one job-id at a time.

How can I get this on a python program so I can manipulate it as an array?
I looked on the net for such function or example and didin't find anything, thus after having made one i guess it would be legitimate to drop it to see what others thinks of it.

local arrayname=$1

i am on processing text tasks And i found that if you assign a text to a variable is chomp'ed automatically the newline
Code:
variable=$(cat file.txt)
The problem is i can only access the items/lines using:
Code:
for line in $variable
do
echo $line
# Other commands
done
how do i convert this to an indexed array. More importantly, how do i get access to individual $line[0], ..., $line[n] Another thing, if the file.txt, has lines with spaces it is a mess using the for...in..., but echoing prints line by line...o_0
Is it possible to have an array in Bash that can hold more than one value per item?
For example I would like an array like this:
Entry 1: apple, green
Entry 2: banana, yellow
And be able to call the fruit names and their colour in a list. Something like:
for fruit in "${array[@]}"
do
echo a $fruit is $colour
done
If that is possible, is there a limit to values per item? For example some entries in an array could be:
Entry 1: apple, green, round, pips, tree
Entry 2: banana, yellow, long, skin, tree
And I would like to pick out the values such as #3 being "round" and "long".
I have this code:
Code:
original_content=${content[@]};
echo ${#content[@]} # is 23
echo ${#original_content[@]} # is 1
I'd expect original_content should be copy of content. How to copy array?
bash 3.1.17(2) I'm trying do write a shell script which must operate on each line of an ASCII text file.
