I found this "if condition check" satisfy my need.

@(pattern-list)
Matches one of the given patterns

Thanks, but it is misunderstood,
the input has to be EXACT match of one of options e.g.
centos-5.5-i386 windows-2003r2-x64 freebsd-6.1-i386
so, centos/freebsd/windows are not valid input
I am...

How to make sure the input string is one of many options e.g centos-5.5-i386 windows-2003r2-x64 ?
The options are dynamic, so "case" condition check doesn't work.

I use grep -o -w , it doesn't...

I don't think you can add a new field in inode structure, but you can use "debugfs" to view/change values of existing fields.

It seems it is Solaris 10.

In Solaris 10, "svc:/system/sar" create cron job "/var/spool/cron/crontabs/sys" to record sar output to "/var/adm/sa"

The sar ouput history can be viewed by "-f".

ssh user1@${server1} /usr/bin/ls -l /tmp/file1 | awk '!/^$/ {print $5}' > ${DATAFILE}

I figured it out, But I don't like the trick of tac.
[Help still needed, Solaris doesn't have tac command.]

$cat t2

delete last X lines,which start with [0-9]+

example file:

one liner shell is preferred.

No, You don't need loop. either one-liner can do the job.

find $1 -maxdepth 1 -type f -not -name "*.old" -exec mv {} {}.old \;



find $1 -maxdepth 1 -type f -not -name "*.old" | xargs -i{} mv {} {}.old

You can get pid with pgrep command in Solaris.


pgrep -f AREmail


If there are multiple AREmail process, either command may get multiple PIDs , You has to use loop to kill each one.

Maybe the service command can't found, try to use /sbin/service ..

If it works, you need to add PATH env variable in cron job.

I found two solutions for the issue.

Solution #1

#!/usr/bin/perl -w
use CGI qw(:standard);
$|=1;
my $r = shift;
print header('text/html');
print start_html;
$r->print ("Processing ......

$| doesn't work, To make it simple, I tested following script. I expect "OK, starting time consuming process " appeared first, then "All done" aftter 5 seconds. But they all appeared all together...

It is a basic Perl CGI question, I want to print out "Processing ... " while backend script /script/wait.pl is still running.

But acctually, nothing appeared in browser untill /script/wait.pl...

Alister,

Can you explain how "n;" means every 2nd line? I undertand the obvious expression.

I use forwarders for a subzone, but TCP 53 is blocked, So does forwarders really need TCP?

BTW: I wan't to loop through each line to do something with "while read", It just missed the last line.
