tee to a compressed file

tee reads from standard input and writes to standard output and a file. 

some_command |& tee log

Is that possible for tee to write to a compressed file?

some_command |& tee -some_option log.bz2

If tee can not do that, is there any other command?

I can redirect the output to a compressed file with

some_command |& bzip2 > log.bz2

But with this command, the output to standard output is missing.

Solution

  • If you're OK having your output on stderr, you can redirect it:

    some_command | tee /dev/stderr | bzip2 > log.bz2

    This tees the output to both stdout and stderr (| tee /dev/stderr). Then it pipes the stdout to bzip2 (| bzip2 > log.bz2)
