manta-compute-bin

manta-compute-bin is a collection of utilities that are on the $PATH in a compute job.

Introduction

Each of these utilities aids in proceesing and moving data around within a compute job. Recall that each phase of a job is expressed in terms of a Unix command. These utilities are invoked as part of the job exec command. For example, if you had the following as your exec line:

grep foo | cut -f 4 | sort | uniq -c

And needed to preserve the grep foo output, you could use the mtee command to capture that part of the pipeline to a object:

grep foo | mtee ~~/stor/grep_foo.txt | cut -f 4 | sort | uniq -c
