Silence the startup command printout in Integrated Terminal

[mymikemiller]

When I run a Dart app in the Integrated Terminal, it prints out a very verbose startup command, e.g.:

cd /Users/mikem/myproject; /usr/local/Cellar/dart/2.8.2/libexec/bin/dart --enable-vm-service=0 --pause_isolates_on_start=true --write-service-info=file:///var/folders/2n/vn59_vz152vg107rrs53ympc0000gn/T/dart-vm-service-ee74.json -DSILENT_OBSERVATORY=true --enable-asserts bin/main.dart

This happens for Javascript too:

mikem@MBP node_sample % /usr/local/bin/node --inspect-brk=6018 scripts/simple.js Debugger listening on ws://127.0.0.1:6018/453abe68-1da3-4862-8ba4-71d8e3dfd8d6 For help, see: https://nodejs.org/en/docs/inspector Debugger attached.

These printouts pollute the scrollback and aren't very useful imho. Could we get an option to silence this output, so the first thing I see in the Integrated Terminal is one of the print statements actually in my code?

Note that this doesn't happen when using the Debug Console. There, I only see this printout (which also would be nice to silence, but at least it's less verbose):

@Tyriar is there a good way to executed a command in the integrated terminal but turning off echoing?

[weinand]

@mymikemiller if the debug console works for you, why are you not using it instead of the integrated terminal?

[ArturoDent]

You can turn off echoing commands in bash for example.

set +x

in your C:\Program Files\Git\etc\bash.bashrc

There is also a verbose +/-y switch in some shells. See https://stackoverflow.com/questions/2853803/how-to-echo-shell-commands-as-they-are-executed

I don't know if either of those would affect the startup commands that you are seeing?

[mymikemiller]

@weinand The debug console doesn't accept interactive input, and also it doesn't allow me to position the cursor absolutely, which is required for a library I'm using to print out nice progress bars.

@ArturoDent I don't think this is a bash thing (I use zsh, but same thing). When I run dart bin/main.dart, my app runs without echoing any command. So this seems to be a VSCode issue.

[mymikemiller]

Btw, I get the same output with bash as my default terminal as I do with zsh:

bash-3.2$ cd /Users/mikem/myproject ; /usr/local/Cellar/dart/2.8.2/libexec/bin/dart --enable-vm-service=0 --pause_isolates_on_start=true --write-service-info=file:///var/folders/2n/vn59_vz152vg107rrs53ympc0000gn/T/dart-vm-service-f583.json -DSILENT_OBSERVATORY=true --enable-asserts bin/main.dart

[mymikemiller]

@ArturoDent Switching to Bash and adding set +x to the top of my .bashrc does not get rid of the printout. It does stop my bashrc from printing out any of its commands, which are printed if changed to set -x.

[weinand]

@mymikemiller are you saying that when you are typing dart bin/main.dart in zsh, you are not seeing what you are typing?

[mymikemiller]

@weinand correct.

In a normal terminal:
