Using awk together with linux mail commands

Patrick Chuang · 03-14-2007, 02:42 AM

Hi Everyone

I am a newbie at Linux. Appreciate if anyone of you guys can help me out..

I am trying to send out the daily log files generated from our application. Currently there is a file - "log_req" containing all the files that need to be sent daily. As a test, the log_req file contains 2 file names. I need to know whether we can use a combination of awk and mail commands to send based on redirection.

The command I am trying to figure out is this:-

awk 'BEGIN{while (getline line_data < "log_req") "mail patrick.chuang@abc.com" < line_data}'

I do not encounter any syntax errors but somehow I dont receive any email. I tested with the print command and the information from the log_req files are retrieved.

awk 'BEGIN{while (getline line_data < "log_req") print}'

What i want to achieve would be to send all the files in the log_req file to the receipient.

Grateful if you can advice.

Thanks
Patrick..

You could get "nail" (which is almost a dropin replacement of /bin/mail) and use it's -a option to attach the necessary files.

Something like this may help too:

Code:

oldIFS=$IFS;
IFS="\n"; #makes it ignore spaces and tabs in filenames
for file in `cat log_req`; do
   mail patrick.chuang@abc.com < $file;
done;
IFS=$oldIFS; #restore original value

Have you tried sending mail to the same address from the command line (just run "mail patrick.chuang@abc.com", type in the message and Ctrl-D to end it). If that doesn't work either, then the problem is with your e-mail setup (ie sendmail config) rather than with your commands.
