ok, I get it
Here you go


sort a.txt | awk -F'=' 'BEGIN {l=null} $1 ~ /Time|Server|Run|Tables/ {if($1 != l ) {l=$1; printf("\n%s ",$1)} else { printf("%s ",$2)}}'

Sorry, I don't understand. Are you saying you want it in that order?

Cool, good luck. I believe when you kill the parent and run setsid, it will disassociate the terminal, thereby putting it in the background.

You can also try ioctl, which is lower level, and I think, gives more control.

Would this work

You can try ssh -vvv to see if the output gives some hint for the failures

I have not used expect so much, but may be you can pass in the ls command in the ssh itself, like so


spawn ssh ..... "ls $filename"

If you provide sample input and sample output it will be much more easy to understand.

To answer 2, to put the process in background, you will have to
1. fork from the parent.
2. terminate the parent so the child is owned by init.
3. and dissociate the tty by setting session...

For synchronous processes you would have to use combination of shared memory and semaphores. I believe you would need it...

sed -ie "s/\(.*sreenivas.*\)/#\1/" <filename>

How about just observing the /var/log/messages file.
Depending on you *nix flavour this may be a different file. This file has entries like

Ok, lemme see if I understand you correct.


from_date=$1
to_date=`date +%H`

for i in `seq -w ${from_date} $t` ;do
echo $i;
## Put your copy logic here.
done

If I understand your problem statement correctly, this should do what you want.

Look for man bash, and search PS1. It has a tonn of option. But if you are lazy like me, here's the quick one

oh my bad,


while read line;do

do you see errors, or the output file is not what you want?

What version of red hat? what shell
Appears to work fine in bash/zsh for me.

$ paste 1 2 3
123 234 456
345 789

try this


while read line;do
ts=`echo "$line"|cut -f1
rest=`echo "$line"|cut -f2-
d=`date --date="@${ts}"
echo "$d,$rest"
done < inputfile > output file

I like to think this may be easier using xmllint (with --xpath)

Assuming your first column is the epoch time
you can do this (from man date)

date --date='@2147483647'

just to be a little more careful

egrep -w -v "^3" <filename>

would be little more safer. I do see a space/tab in the above regex, but a -w will ensure you are deleting like that as your id as...

Why not just do cp -r source dest?
