Thank you for the response. I can't recall on how I started assuming that runlevel scripts have priority.

Absolutely sure that no one restarted the process. The weird thing is that the Date is correct "Jun 17", just the time is incorrect.

According to the time 00:16:41, it should have displayed "Jun...

Which of the following gets executed first?

script under rc3.d Vs script under rc.local

I was under impression that rc3.d has higher precedence over rc.local. Somehow it looks like the script...

Check out the below post on cron and crontab:

Lets see what kind of questions you have after that..

The above two solution would add .txt to the file names.

But, as Jallan mentioned - he/she would be running a cron job everyday to add .txt to the new files add to that directory.

The above...

Considering the ''expr' error that you are getting is from the code where you are trying to 'trim', than use the following:



trimmedMID_INFILE=`echo $MID_INFILE | cut -b 1-$len`

Below should do it..



while read nodename
do
/opt/OV/bin/ovet_topodump.ovpl -nodeif $nodename -detail
done < nodes.txt

Is this a school project ? :)

If the length of the Segment is fixed -> 4 characters, than why do you need to have the rest of the junk in the output
eg:

1001A0010@
B0010*&^0)

This is one way to do it...
I'm sure someone will have a shorter code than this.



while read record
do
uniq_id=`echo $record | awk -F'A' '{print $1}'`
part1=`echo $record | awk -F'B'...

You could run the following command:

sed '/^$/d' < file1 > file2

file2 is the one without blank lines.

some of the version of sed allows '-i' switch to do in place. It saves the output in...

Denn,

you are right.

1. ls -l | awk '{print $9'} = ls -1 (no need for extra code)

Jartan,

Did you try what Denn provided?

ls -1 | xargs pkginfo 2> /var/tmp/errorfile

If the...

Wow. It is just surprising that its not catching either std err or std out.

Lets try this:

ls -l|awk '{print $9}'|xargs pkginfo |grep -i error 2>&1 | awk -F'"' '{ print $2 }'


no while...

From what denn mentioned above, try the following:

ls -l|awk '{print $9}'|xargs pkginfo |grep -i error 2> temp1.txt

and then the while loop...

:-)

I apologize. I overlooked the 'ls' part.

The quick way would be:

ls -l|awk '{print $9}'|xargs pkginfo |grep -i error > temp1.txt

while read record
do
echo $record | awk -F'"' '{ print $2...

I'm sure you are checking on each package at a time.
I guess you can try breaking into two steps:
1. Capture the error in variable
2. Run awk on the variable

example:

temp1=`ls -l|awk...

Hello,

If I understand the question correctly, you need to export the variable using the 'export' command.

Is that what are you trying to do?
