I know that I can do this in bash
ver=${VERSION:-$DEFVERSION}
so ver is $VERSION if it's set but $DEFVERSION if $VERSION isn't set

I want to do the same thing as a macro in a Makefile and can't...

Try creating two files with the required time stamps using the touch command and then retry the find using -newer
e.g.
touch -t 201001010001 t20100101
touch -t 201001060001 t20100106
find -type f...

Server. Does it make a difference?:confused:

Your while loop will re-enter the same piece of code if you don't increment the step count, so why not increment it in the "No Error" if block, rather than outside the case statement.

By the way,...

I'm looking into a Solaris(S10) startup problem, with a script configured to run in /etc/rc3.d. It's written to output trace information to a logfile using tee, but the file itself is clearly not...

I've had various issues with trying to use mtime and ctime in the past, so my usual method is to touch a file with a date time stamp of, say, a year ago
touch -t 20130813 ref_fileand then use
find...

A few things...

First, set -x
in the code or #! /bin/ksh -x
as the first line will provide verbose debug output and typically makes things much more obvious.

Secondly, you would normally use...

Alternatively - not better, but arguably easier to understand, and works in Bourne shell as well

if [ "$hostname" = "red" -o "$hostname" = "black" -o \
"$hostname" = "green" -o "$hostname"...

So, you're incrementing the linecount and then using that to as an argument for the 'head' command, which will then return that number of lines from the top of Usernames - is that really what you...

Add a 'set -x' into the script to see what it's doing...

You could try symbolically linking the .c file to the .syn file rather than copying it, so as soon as the .syn is updated, the .c tracks it, or you could write the rules in your Makefile to deal with...

What's the technical difference between an ipnode and a host.

I have a problem that my Solaris host has a one hour delay in tracking a 3DNS change elsewhere in the network (ping -s alias).

Can anyone explain how you can get a SIGPWR signal on a Solaris 10 local zone, but none of the other zones on the frame had a problem. :confused:

You've got 2 read statements with an echo between them. Putting them on the same line in the script won't make them behave as a single read.
You'll have to read the entire "min -- max" line in a...

I'm not sure what you're trying to achieve...it will be very easy to place the array data in a hash in exactly the same way that you're printing your output, but you'd then need to print the hash, so...

You've used the -a option for tee which appends instead of overwrites the file

The $$ in the gcc line, I believe, will be different from the one in the sed line, so your sed will be operating on a different file from the one generated by the gcc. Try storing $$ into another...

I guess that the problem is due to the [[ ]] in the rotate function.
You need cat_while_read_LINE to return true (0) for the while loop to continue and false (non 0) for the while loop to...

Try running make with the -d option and see what it tells you.

Perl has a built in 'stat' command. Is this available to you?

How about the curl "retry" option?

curl returns an non-zero exit status when you get an error and a zero exit status when it works so to handle it in the shell, try...
while ! curl -T file.wmv...

Thanks all

In the IP addresses 193.32.156.0/24 and 169.183.0.0/16, what do the /16 and /24 represent?

How about...

#!/usr/bin/perl


my @src=`ls /home/t1/`;
my @dest=`ls /home/t2/`;

SRC: foreach my $src (@src){
DEST: foreach my $dest (@dest) {
if ( $src eq $dest ){

a='03'
or using Korn shell print it out in the correct format
a=3
printf '%02d\n' ${a}
