I am passing an array in function. I want to read the first content again and again until it is empty so
function calltoarray
{
read $1[0]
while [ ! -n "$1[0]" ]
do
echo empty
read $1[0]
done
}
But the code is not working. If we just press enter without value at read $1[0]. It do not get into while loop.
I am trying to create a shell script to automate a process that takes inputs from two sets of data. The variable SHELL in my system echoes as /bin/tcsh, but I see that my /bin directory has other possibilities, such as bash. So, if changing the shell could simplify my problem, then I would go with that.
I have a list of files containing data about objects, say
obj1.dat, obj2.dat, .... objn.dat, where n is around 20 (it varies).
These objects belong to a few different categories, and there are files detailing the properties of the categories, say
cat1.prop, cat2.prop, ... catm.prop, where m is smaller than n (more than one object in each category).
I know that shell scripts can handle 2-d arrays, although I am not sure how. The thing here is that category 1 could have 5 objects and category 3 could have 7 objects. So, this could produce a 2-d array, but not a rectangular one. I need to process these files taking into acount the data about the object and the properties of the category the object belongs to. Here is what I tried to do:
# First I enter a list of category names and m lists of objects in each category
category='cat1 cat2 cat3 ... catm'
cat1-obj='obj1 obj2 obj3'
cat2-obj='obj4 obj5'
cat3-obj='obj6 obj7 obj8 obj9 obj10'
.
.
.
catm-obj='objx objy objz objn'
# The lines above show the irregular 2-d array. Then I try to trick the script into parsing through this irregular 2-d array:
for i in $category
do
data='$i -obj'
for j in $data
do
mycommand $j.dat $i.prop > $j-$i.out
done
done
The line "mycommand $j.dat ..." is just the line that processes the information. That has been tested to work fine. Feeding the information to this is what does not work. The lines " data='$i-obj' " and " for j in $data " do not have the desired effect. I have tried other ways, like data=`echo $i "-obj"` and things of the sort, by to no avail.
1. How do I create an array with 5 entries
2. Output one of the entries in the array randomly
3. Subtract the entry output from the array
4. Repeat steps 2 and 3 until there are no more entries in the array
I made a little rsync script for log transfer.

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 been trying to write a simple snip of bash shell code to import from 1 to 100 records into a Bash array.
I have a CSV file that is structured like:
record1,item1,item2,item3,item4
record2,item1,item2,item3,item4
record3,item1,item2,item3,item4
record4,item1,item2,item3,item4
And would like to get this data into corresponding arrays as such:
$record1[item1-4]
$record2[item1-4]
$record3[item1-4]
$record4[item1-4]

I'm writing a PHP program. I've encountered a problem; in the following code I try to pass $_POST['delete'] which is an array as the value of a hidden input to some form, but it doesn't do so.there's something wrong with converting PHP array into HTML array.

I have a QNX machine with a slinger webserver running on it. With a cgi script i'm trying to do the QNX cksum call and compare it's output value with a fixed output. When i execute the script at the command line it works perfect, but when execute this script by by the webserver in my browser it doesn't work. Here's my code:

I have this one last task for this app I've been working on (should have picked something easier for my first project)
It has working "def sav_scr_vars" and "def AddEntry" but these save to a fixed filename when save as defults or ok button is clicked. This is fine but I want to be able to save via the same proccess to a named ~/bin/settings/xxx.set file what I did is clone the to above def's and try to edit them I got the "read file" to work fine from a saved file in this manner. but I can't seem to get the save to filename to work without errors. The cloned def's are "save_as" and inmain.py "write_config2"
the camm2.defaults file goes in ~/.hpgl
copy and paste this to ~/.hpgl/camm2.conf
~/.hpgl/camm2.defaults
The file is always to have a .set extension and only read and write to ~/bin/settings

I wonder why arrays in the C programming language are pointers to the first element of the array, not the first element of the array itself?

This is regarding the KDE application Basket:
I want to create a shell script that I can run as a cron job to do automated backups. how to proceed. I have the source code and have pulled out the backup source files. Here is the link for the source code. The download is at the bottom of this page. The backup files can be found in the src folder listed as backup.cpp and backup.h [URL]
If someone can do this, I believe it will make a nice addition to the Basket application for all.

I cannot tell why the login timeout is expired when I try to do this, and my investigation toward this end has been fruitless. I saw a brief snippet on Google that vaguely suggested that the underscores in the domain name were at fault, but replacing these with their encoded counterparts did nothing to resolve the issue (that, and underscores should be fine when sent unencoded according to the standards). I have extensively perused the man pages and have come up with nothing to adequately explain this behavior. I also talked to a friend who has worked with curl in his line of work, but he mostly has experience in the context of PHP and has not dealt with this issue before. I am running GNU/Linux 2.6.35-22-generic-pae.
I've created a simple script based menu. This menu will be accessed by only a certain users via ssh.When user logs in, the menu will automatically run. (configured at user's .bash_profile).How do I force the session to close when user hits Ctrl-C or Ctrl-Break ?In a nutshell, I don't want user to have access to shell.
