python - Piping explicit conda list -


i need pipe conda commands: 

$ conda list --export | head -n 3 # file may used create environment using: # $ conda create --name <env> --file <this file> # platform: linux-64

this works fine. piping explicit list fails:

$ conda list --explicit | head -n 3 # file may used create environment using: # $ conda create --name <env> --file <this file> # platform: linux-64 unexpected error has occurred. please consider posting following information conda github issue tracker at:      https://github.com/conda/conda/issues    current conda install:                 platform : linux-64           conda version : 4.2.12        conda private : false       conda-env version : 4.2.12     conda-build version : not installed          python version : 2.7.12.final.0        requests version : 2.11.1        root environment : /home/me/miniconda3  (writable)     default environment : /home/me/miniconda3        envs directories : /home/me/miniconda3/envs           package cache : /home/me/miniconda3/pkgs            channel urls : https://repo.continuum.io/pkgs/free/linux-64                           https://repo.continuum.io/pkgs/free/noarch                           https://repo.continuum.io/pkgs/pro/linux-64                           https://repo.continuum.io/pkgs/pro/noarch             config file : none            offline mode : false    `$ /home/me/miniconda3/bin/conda list --explicit`

the traceback (sorry, wont allow me put inside code tags...):

traceback (most recent call last):     file "/home/me/miniconda3/lib/python2.7/site-packages/conda/exceptions.py", line 479, in conda_exception_handler return_value = func(*args, **kwargs)  file "/home/me/miniconda3/lib/python2.7/site-packages/conda/cli/main.py", line 145, in _main   exit_code = args.func(args, p)  file "/home/me/miniconda3/lib/python2.7/site-packages/conda/cli/main_list.py", line 213, in execute   print_explicit(prefix, args.md5)  file "/home/me/miniconda3/lib/python2.7/site-packages/conda/cli/main_list.py", line 190, in print_explicit   print(url + ('#%s' % md5 if add_md5 , md5 else ''))  ioerror: [errno 32] broken pipe

that's bug right? without piping works fine.

the broken pipe occurring because head closing output stream once gets 3 lines has been instructed show. you'll notice 3 lines in output. next time conda tries print, cannot because head has closed pipe. causing exception. not problem conda. have here further information regarding broken pipe exceptions in python: ioerror: [errno 32] broken pipe: python

now potential work around:

$ conda list --explicit > /tmp/conda-explicit-output && head -n 15 /tmp/conda-explicit-output && rm /tmp/conda-explicit-output

yeah it's pretty ugly, job done.
