Describe the bug

When I paste large blocks of code in SSH sessions, they appear fine in the terminal, but when executed, the start of random lines are cut off in the interpreter and the commands fail. I think it has something to do with the SSH wrapper, as I have only observed this during SSH sessions, but that's also where I paste large blocks of code. It also only seems to happen to specific lines, but I have no intuition which lines are going to be affected. When a line is affected, that line is always affected when the block is re-run, though the number of cut-off characters sometimes changes.

To reproduce

For example, if I paste the lines:

module purge
module load gromacs/2023.3
gmx select -f umbrella0/md.gro -s umbrella0/md.tpr -on C2.ndx -select "name C2"
gmx traj -f ../run2/md.xtc -s ../run2/md.tpr -com -n C2.ndx -nox -noy -ox C2_z.xvg

the gmx select command throws a bash error:

bash: ect: command not found

e.g the start of the line is cut off
The surrounding lines all run fine (or rather, the next line fails because the output file from the select command is missing)

Expected behavior

Pasting code into the terminal should run the pasted code.

You may need some clipboard (copy/paste) dependencies.If you're on wayland, try the following:

sudo zypper install wl-clipboard

If on x11, try this:

sudo zypper install xclip
# or
sudo zypper install xsel

If the issues persist, as a workaround, you can add command ssh to your Settings > Subshells > Added commands menu, then run command ssh <user@server> to connect to a remote session, which will attempt to enable Warp features as a subshell.

If that doesn't work, please let us know.

Sorry, I was unclear about the operating system. This is Warp running on MacOS, but the SSH session is connecting to a RHEL server, which is where the commands are running and failing.

I tried adding command ssh to my Subshells list and connecting with command ssh, but the issue persists.
