I'm trying to delve into the world of multithreading and I'm having some difficulty... Typical producer-consumer results in an IllegalMonitorException.

Java, Java, Java! I like c/c++; however, it seems the job market is Java crazy particularly at entry level. Also a huge demand for web developers. HTML,CSS,JScript, and PHP are a good place to start....

I toying around with chef and box grinder and I've encountered a problem I'm trying to work around. I have an iscsi I'm trying to auto mount. Doing so thru the fstab doesn't do the trick. Any ideas...

Assuming a user doesn't tweak the file itself there won't be any blank lines. The script takes information and stores it in a delimited file, and won't accept blank input so hopefully I'm covered =)...

i just threw the wc in there, i ended up with



while read line; do
#echo -e "$(awk -F':' '{print NR, $1, $2, $3, $4}')"
let count++
echo $count $line
done < <(awk -F':' '{print...

I'm building a script that accesses a file. I've currently put 8 records into the test data but when I try to list with line numbers I get 7 rather than 8...

Ok so here goes, I'm making a menu driven program for a project and I'm looking for feedback. I still need to tighten up the error handling (if exists etc.) but I welcome any feedback. Please let me...

main_menu_function()
{
while true
do
echo "********************************************************************************"
echo "* Main Menu ...

Let me see if I'm understanding and try to expand on what you've said...

so in the case of 4) Exit have it set a parameter to whatever and check in the conditional statement to exit the script?

echo "********************************************************************************"
echo "* Main Menu *"
echo "* ...

You end up with 5 + 4 + 3+ = sum using this method I managed a work around its ugly but I learned something lol

I'm trying to make a bash menu displaying options but it contains sub menus as well. Is there anyway to add an identifier that will display with the menu?

Right now it displays

Kind silly but I'm getting an infinite loop passing command line args to a while loop and attempting to sum them with the output shown as

var1 + var2 + var3 = sum

Sounding like awk is the way to go, I was thinking I could just use read line, and then refer to the different variables much like in the command line arg syntax, $1, $2 etc, I'll get some code...

I have a number of records in a file, each contains 25 fields. I need 2 of these fields assigned to variables. Everything I've come up with thus far isn't working...

my while read line; do just...

Not sure I followed.

So for file in a directory set a variable equal to the whatever the file command returns, then compare this variable to "shell script" or something similar, if yes display,...

find -executable only looks for those marked +x

file on the other hand will list if it is a shell script, guess the issue I'm having is the logic.

If part of the file returns "shell script",...

#!/bin/bash

#scriptfinder.sh

#check for arguments
if [ ! -z $2 ]; then
echo "USAGE: Too many arguments"

#if argument is empty
elif [ -z $1 ]; then

As silly as this sounds I'm trying to put together a lesson plans for young kids i'm not sure they'll understand for loops and iterating thru a sequence >.<

echo -e "*****************************************************"
echo -e "** **"
echo -e "** Now let's create some files in **"
echo...

That'll work but I'm trying to keep this as simple as possible.

I need the shell to interpret the variable literally, if for example:
$var = ~/dir1/file1

I should be able to touch $var and get...

read files_to_create

touch $files_to_create

I tried using grouping in the script but ended up with braces etc in the file names.

I'm trying to get a single var from a user and then create files based on that, very rudimentary but I can't seem to get it right.

i.e.
variable ~/make/this.txt ~/file/over/here.txt

should...

Damn these old eyes ... thanks!
