Hello, I have been trying to figure out why the wait isnt waiting for the sleep process to complete till now and have found out that since sleep runs as different process and not a child process the...

Thanks Era and Danmero..

Both your solutions work great! but i would go for the grep option as i am using the grep -f option which is not available with awk.

Era.. your grep solution can be...

Hi Era,

Thanks for your reply...but with grep -o 'is\.it' file , the output would be as follows

is.it
is.it

that is "is.it" appears twice in the output...I know we can do an uniq to get it...

This might sound easy but its not...

I have a file a with the following data...including the 1,2 and 3

1 this.is.it
2 is.it
3 this.is

now i need to grep for "is.it" ONLY in the file...

Thanks Madhan...

What if the script takes in two input parameters..it becomes tricky then eh?

First parameter-$1-email
Second parameter- $2 -number(eg: 400 ,300)

awk '$1 == $2' abc.log...

Hi,

My script takes in one input parameter($1-email id) on the command line...

The script contains something like this...

awk '$1 == 400' abc.log >def.log
mail -s subject $1 <def.log
...

-E doesnt help too...

I came around with a workaround using awk -F ! :-)

This wont help..
Print NUM lines of trailing context after matching lines..


Instead of lines I need pattern


Eg: Say i search for a pattern abc...the result i get is hdhd fhfhfh abc hdh...

When i grep for a pattern the search results comes up with matching lines(some before the pattern and some after)...how can i limit the search so that it shows only the lines after the pattern...

Why didnt i think of this :-)

Working Gr8! Thanks!

I know this works when you type this in the command prompt..I can type my own body and its done..

My concern being the same cannot be reproduced if I put this in a script and want the body...

Hi When i use the syntax given in the site ..i get a ">" after executing the below line

When i type the below and hit enter
cat <<content | sendmail -t a@b.com


I get this
cat <<content |...

what is the syntax for sending a subject ?

sendmail -t a@b.com

The person receives the mail with an empty subject!

the man pages dont give anything related to subject...anybody??

okie...just came out with a work around :-)

Sorry by using grep thrice totally not four times :-)

If i do this
cut -d"/" -f5 | egrep -e "p2"
it will be grepping on the output because we are using the pipe....

grep pattern a.log|grep -e "p1" |cut -d":" -f1,2,3,4,8,9,10|cut -d"/" -f5 -e...

well i need that -e there as i wanna search for another pattern....do u think i need to use braces anywhere?

grep pattern a.log|grep -e "p1" |cut -d":" -f1,2,3,4,8,9,10|cut -d"/" -f5 -e "p2" |cut -d":" -f1,2,3,4,6|cut -d"/" -f5 >> file

Dont know why the above command isnt working :-(

can someone...

tail -f just displays the realtime appended output of the file...not just the 10lines

anyways i figured out a way using awk..but would gr8 if we can do it using grep

I am trying to extract a particular line from a.log which keeps appending every sec and output that into a newfile b.log which should append itself with filtered data received from a.log

I tried ...

Sudo is installed on the remote system...sudo works when i login to the remote system without ssh. I have used -t bcuz i was getting a notif saying &TERM and -T is not specified.

I am trying to execute a command via sudo through ssh...

ssh -t a@b "sudo command"

what could be the prb?

Just tried ssh -t option and i am not getting that error anymore!
