Shell Programming and Scripting

Hello All,
I have some unique requirement.
I have written a very lengthy script which calls number of resource script to execute a particular task.
What I want is output of each command(called from main script and resource scripts) should go to a particular file and I should be able to access that file within my main script (Just want to attach it to mail.). Only output of "echo" command should appear on console.
Is there any way to do this ? I thought of

Code:

"Script"

command but it prints output to console as well.
Another way is to redirect output of each command to file but I have more than 2000 commands in total so that looks tough and something that I want to avoid.
Thank you very much.

Regards,
Anand Shah

Not sure what you are up to... Have you considered using tee command?

Hello,

ok I think we have to keep some few things in mind here like file should STOP updating before sending to it mail as attachment, we can put a sleep process for 1 or 2 mins after your script completion. Then we can fetch the file and snd it to mail as an attachment.

For scripts which you want to execute in Bacground or you don't want their output to be shown at screen please use nohup command for same.

try this and let us know if it works ...

script > /dir/log 2>&1
in your script, do

Code:

#! /bin/ksh

admin=admin@some.com

some_command 
some_script 
...
some_command
some_script

if [ -f /dir/log ]
then
      cat /dir/log | mailx -s 'logfile for script is ready' $admin 
else
     echo "script has no entries in /dir/log up to this point" >> /dir/log
fi

exit 0

or ...

you can just create one big function in your script and redirect the output for that function into one log file ...

Code:

#! /bin/ksh

admin=admin@some.com

myfunction(){
    some_command 
    some_script 
    ...
    some_command
    some_script
}

myfunction > /dir/log 2>&1
echo "i'm done"

if [ -f /dir/log ]
then
      cat /dir/log | mailx -s 'logfile for script is ready' $admin
      echo "i am done. report emailed to $admin" 
else
     echo "script has no entries in /dir/log up to this point"
fi

exit 0
