Thanks again vgersh99.

I tried this but there seems to be a problem since $var is 1.00, and not just 1. It says error token is ".00". Potentially the string could be any decimal number, so I guess I don't want integers,...

I suppose the variable is a string, not an integer. How would I convert this to do some arithmetic operations on it?

Thanks vgersh99, that did it.

When I run time -p <command>, it outputs:
real X.XX
user X.XX
sys X.XXwhere X.XX is seconds. How I can take just that first number output, the seconds of real time, and assign that to a variable?

Anyone know anything about this?

Hi all. I was able to set up an IBM Ultrium LTO 4 tape drive to use iSCSI (using open-iscsi drivers) to communicate with Red Hat, but it's going really slow, maxing out in tar and dd tests at like...

I've starting playing with a tape drive for the first time. Its a new one, an IBM Ultrium LTO 4. After initially copying a file to the tape with tar cvf /dev/st0 /root/dummy, all subsequent files...

When I do

time tar cvf /dev/st0 /mnt/junk >> /root/benchlog, I want it to put the output of the time command into the benchlog file, but it put /mnt/junk. How do I get it to put the output of the...

I'm trying to write a simple bash script and I need something like
var=2^(5+i)
where i is another variable. How would do I this in bash?

Say I have (in psuedocode)
For i=1 to 10
tar cvfb /... 5*i /junk(i)
end

What I mean is that I want each successive for loop to have the block size parameter be 5 times the current counter. ...

Yet another question. I want to make something like this:

if [ $number1 -le 10 ]||[ $number2 -le 10 ]&&[ $number3 -le 10]
then
...
fi

but that apparently is not right. I want either the...

Another question, is it possible to, in a for-loop incrementing until it reaches a certain number, to have it loop again without incrementing? Just have it drop what it is doing when it reaches this...

Hi, I'm trying to do something like this: range= `expr `date '+%m'` - 1` and it does not work. How can I tell it to evaluate an expression within another expression evaluation? I was at first...

Thanks a lot!

I'm new at scripting but I thought I was getting pretty good at it. I've hit a snag. I try to use expr to compute a fraction say: expr 3 / 4, and I'm getting zero. I guess it's just truncating to...
