[I apologize if this doesn't thread correctly: I've been getting the digest, and can't respond directly. And I have no idea how my name ended up in the Subject line: Rookie Move!]
More debug information, and a workaround/solution: I am running: Windows 10 Version 1909, fully patched. Cygwin v3.1.6-1 Openssh v8.3p1-1 mintty v3.2.0-1 tcsh v6.22.02-1 The issue seems to be a race condition setting up ssh-agent, and then immediately starting up the the mintty/tcsh terminals. My guess is that something in ssh-agent is not fully setup yet, and is causing read hiccups in mintty. My startup script looks like: #!/bin/sh if [ -z "$SSH_AGENT_PID" ] ; then echo "Starting ssh-agent" eval $(ssh-agent) ssh-add #sleep 3 fi C:/cygwin64/bin/mintty.exe -i /usr/share/mintty/icon/wsl.ico \ --position 0,0 --size 80x24 --fg black --bg white /bin/tcsh & #sleep 1 ...9 more invocations deleted... Without the sleep 3 after starting ssh-agent, I see one of three conditions: 1. The mintty window is created, but immediately crashes printing a dozen or so "Use "exit" to leave tcsh" before it does. At least that I think it says, it happens fast! ;) 2. The mintty window is created, and is ready for input. On the first keypress, it prints a dozen or so "Use "exit" to leave tcsh" and crashes. 3. The mintty window is created, and hangs. No prompt. I get conditions #1/2 when I don't pause between mintty invocations. I get condition #2 when I pause for 1 second between mintty invocations. If I pause for 3 seconds after starting ssh-agent, then everything works as expected. Note this issue occurs only during the first setup of 10 terminals. Running it again does not tickle the issue, probably because ssh-agent is fully up. Hope this helps.
