Could I ask why you wrote the script the way that you did?

I think that you should be able to do everything you want to directly in perl or by making calls to the shell from your perl script. At...

I'm no DNS expert, and I'm hoping someone would be able to help me with this issue I'm facing.

I have a set of links in the following schema:

Math::BigFloat could express atoms in meters, so I figured that wouldn't be an issue. Likewise, I assumed that more than a couple of decimal places were necessary. If this is just for a limited...

My Deutsch isn't all that great, so to make sure I'm clear on what you're doing here - you want to find the number of steps between between two constant values.

Isn't this essentially a division...

The shell will not allow you to loop using a floating point value. As a general rule floating point values should not be used in loop counters even when the language allows it.

If you want to check the value, you'll need to do something like this:


#! /usr/bin/perl -w

use Data::Dumper;

my @array = ("apple","ball","cat","dog","elephant");

$_ = pop(@array);
...

Nice, though that does fail in the case where there is a leading space on a record.

Also, I realized I forgot to skip the header (:rolleyes:) - hope you don't mind my lifting from your code.

I'd recommend, as did malcolmpdx, using a package manager if one is available.

If you don't have one though, gcc can be built from the tarball you have as it has bootstrapping capability. Do note...

What I'm doing here is checking to see if a line has 'Route Distinguisher' in it, and if so then storing the key string in a variable ($buf). If not then I'm storing the values into a hash of arrays...

#! /bin/bash

y=1;

for x in *.gif;
do mv $x file0$y.gif;
y=$[$y+1];
done;

Good suggestions. If I could be bold enough to suggest a couple of modifications, though...

Input data:

Unless you know what data to expect, there's no way to reliably determine what the delimiter in a file is.

Can you elaborate on "the file contains many values and not just 1"? Does this mean...

The -z (http://tldp.org/LDP/abs/html/refcards.html) is testing to see if the string is empty.

If the test (square braces) fails then the assignment part after && doesn't execute.

Might as well post whatever script you have built so far as well.

The code resulted in alpha sorting, rather than numeric sorting, when I tried it.

This modification seems to produce results that are numerically sorted:


a=1
for s in $(echo * | sed...

Tough to do this with just a regex.


#! /usr/bin/perl

open(INPUT, "<input.data") || die ("Couldn't open input data");
open(OUTPUT, ">output.data") || die ("Couldn't open output data");

Try this:


sed -e's/\<FOO\>\W\+\<\(.*\)\>\W\+\<BAR\>/\1/'

Try this:


sed '
s/[^0-9. ]*//g
s/ \+/ /g
' test.html

Beginning Perl (http://www.perl.org/books/beginning-perl/) is a pretty good resource, and the price is right.

Also, the ($_,ZZZZZ) bit is unnecessary - use the following:


rename($_,...

foreach (<*.txt>)
{
rename($_, substr($_,0,7) . substr($_,21));
}


If you're doing this in an existing script I'm assuming you'll need to glob (http://perldoc.perl.org/functions/glob.html) the...

Modifying the $HOME variable worked out.

Thanks!

I'm writing a script which needs to run under an 'automation' account and there is already a .netrc machine definition for the server I need to connect to.

If I create a new machine entry in the...

That little guy looks like he'll provide more forks than I have in my kitchen.

Variable for password request did not resolve properly.

This'll take care of it:


awk -f mouse.awk RS=" " ORS=" " animals.txt



$ cat animals.txt
cat dog pig
deer elk rabbit
mouse mouse mouse

$ awk -f mouse.awk RS=" " ORS=" " animals.txt ...
