Purpose

Want to be notified remotely when a job has been finished (through email).

Also, include a few lines of final results (stdout a.k.a. console output) as the content of the email.

Solution

Use tee command to make additional file with the content of stdout.

Use tail command to get a few lines of the last printed output after the job finished.

<job command> | tee <console output file path>; tail <console output file path> | mail -s "<mail title>" <mail address>

For example,

scons build/X86/gem5.opt | tee ~/temp/output.out; tail ~/temp/output.out | mail -s "gem5 X86 build completed" abc@abc.com
