Assuming your awk is nawk, you can (probably) do this:
The regexp may need to be adjusted to /PORT=[0-9][0-9]*/ if your awk doesn't like the +.
If your output may actually come out on multiple lines per the formatting of your original post, but the "port=" and its port number will always be on the same line, you can shortcut the above this way:
The secret here is to realize that the pattern does not have to be a regular expression. Be a little careful: There's only one RSTART/RLENGTH pair, so more than one "match" in an expression (in the pattern or the action) will only get set RSTART & RLENGTH for the last "match" evaluated.
hi,:)
onsider the followinf two lines
J="$(scriptbc -p 8 $I / \(12 \* 100 \) )"
N="$(( $L * 12 ))"
In the first line I put \ before * like \* and its working fine.
But in the second line if put \ before * i am getting parse error.
What might be the reason?Any idea pls.
cheers

I need a script that will always return an engine of table, which not
depends on the table structure.
I need it to be done exactly from the "show create table ..." statement.
If there is a easiest way, except "show table status", please write.

On the command, when I type in certain commands, they will display a prompt waiting for some input. When I type in the requested input, it will display the info I requested.
For example, if I enter the telnet command, it will display a telnet prompt and wait for me to enter something.

escape
escape(1) Mail Avenger 0.8.3 escape(1)NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`

BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
