How to match (whitespace digits whitespace) sequence?
Hi
Following is an example line.
I want it's output to be
200
However this is not the case. Can you tell me how to do it? I don't want to use AWK for this. Secondly, how can i fetch just 300? Should I use "\2" for that?
When i use the following code
200 gets replaced by TEST. If it can MATCH 200, why is it not showing it?
I'm trying to find a command that will trim the white space off a string.
e.g.
$str = " stuf "
$str = trim ( $str )
echo $str // ouput would just be stuf
Thanks, Mark (4 Replies)

again upto 300

Hmmm... Bash doesn't parse whitespace with a read.
lev@sys09:~$ read line; echo "$line"
test
test
You can imagine what this does if you're using a shell script to read a list of unknown file names containing unknown spaces.
lev@sys09:~$ read word1 word2; echo "$word1,$word2"

Hi guys,
I am working with large data sets and often times realize that not all of the columns are aligned correctly (sometimes rows will be shifted). So when I try to do something like:

hosts
HOSTS(5) File Formats Manual HOSTS(5)NAME
hosts - hostname to IP address database
SYNOPSIS
/etc/hosts
DESCRIPTION
The hosts database lists the IP addresses and the hostnames that translate to these IP addresses. It is used by nonamed(8) in a network
without name servers. A simple /etc/hosts may look like this:
127.0.0.1 localhost
192.9.200.1 darask
192.9.200.2 burask
The localhost entry lists a special address that refers to the local host itself (a kind of /dev/tty for hosts.) You should only list it
if nonamed needs it! The other entries are actual machines. The file may contain comments marked with '#'.
You can have aliases (more hostnames on the same line), but it is not recommended, because nonamed can't present them to the system as
CNAME records. An often seen form like
192.9.200.1 darask.home.cs.vu.nl darask
is harmless though, and has the small advantage that you can use the short name in /etc/ethers so rarpd can match it at boot time.
