vim displaying ^[[32m while redirecting output to file using ssh from iterm

Question

I am sshing from iTerm2 to an Ubuntu machine. I am using ns3 through waf and redirecting my output to a log file using the below command:

mpirun -n 16 ./waf --run test > log.out 2>&1

The log file that gets generated has output like below:

^[[32mWaf: Entering directory `/home/workspace/ns-allinone-3.25/ns-3.25/build/optimized'^[[0m
^[[32mWaf: Entering directory `/home/workspace/ns-allinone-3.25/ns-3.25/build/optimized'^[[0m

I am unable to understand why the extra characters are being added in the file. When I use less to view the contents, I see the output perfectly fine. What should I do to not see the extra in vim.

Those look like ASCII color codes. Check answer here: https://stackoverflow.com/a/10592852/3101082 — dub stylee, Aug 25 '17 at 00:12
The above does not seem to be working. To add I am using solarized light theme on iTerm2. Can that be a cause? — thenakulchawla, Aug 25 '17 at 00:23
Could you take a look at the man page of your tool to see if it has a `--color` param or similar? — romainl, Aug 25 '17 at 05:37

If your vim echo has('conceal') return 1, try this simple solution to hide ^[[32m

syntax match Special /^[\[32m/ conceal

Note: you'd better copy ^[ from the log file for it's actually a Ctrl-[
