no - a job is still a single process. Jobs in fact are controlled by their Process ID.

eggi has it right - basically the only "difference" is that you can manage a job through the job manager...

I didn't realize you could call vi in a script like that and execute sed from there - I always sed the file and output to a temp file, and then read back in to the original... this is much cleaner.

A job is a process running in the background.

E.g.

./myscript.sh &
[1] myscript.sh 96243

A job relates to a command run from a terminal. It is attached to a terminal session. A command...

^ Nice and simple, just the way I like it... though I'm more interested in the sed example.

with my above function:


while [ "$*" != "" ]
do
working_arg=`test_upper $1`
if [ "x${working_arg}x" != "xx" ]; then
echo "$working_arg is all lowercase."
fi
shift

Which part are you having trouble with?

I would have to know a little bit more about the naming scheme of your zip files and etc.

Try this:

function test_upper {
test=`echo $1 | grep [A-Z]`

if [ "$?" = "0" ]; then
#Uppercase letters found.
#translate to lower case:
echo $test | tr '[A-Z]' '[a-z]
else

The text is available, it was just a bit hard to read because you hadn't enclosed it in code tags.

It doesn't look like an overly complicated script - though I wonder if you have racadm installed?...

Niether of those solutions worked for me exactly as specified, however the following command worked fine:

The best thing to do would be to find someone who is fluent in both vbs and shell scripting in order to have them convert the script for you. This may cost some money, especially depending on the...

Hey,

In order just to type the name of the file to execute, it needs to be in an executable directory - so for e.g. if you have a script that is used frequently, drop it in /usr/local/bin and it will...

#usage myscript.sh filename

filename=$1 #read argument "filename"

if [ -f $filename ] #if file exists
then #print it
lp $filename
else #create it
touch $filename
fi

username="myUser"
password=`cat dummy.txt`
# alternatively:
#password=$1

alright, if no one else is going to spill it, method 4 is "echo pwd"

1. PATH="${PATH}:echo pwd" # echo pwd
2. PATH="${PATH}:" # null
3. PATH="${PATH}:." # dot
4. PATH="${PATH}:${PWD}" #$PWD

I don't know of any command that will do this directly for you - and awk would probably be the way to go, but I'm no awk guru. This could probably also be done through some very impressive sed magic...

What this question means is "What can you specify in your PATH environment variable which wil allow you to run scripts in the current directory."

For instance, my default PATH variable is:
