Exit code of a command in xterm

From a csh script, I would like to open an xterm and execute a command and then access the return value by saving it in a file. 

xterm -e "MyCommand; echo $? > ./log.txt"

This does not work. $? always returns 0 even if I replace MyCommand with something that does not exit.

I know this question is very similar to this but it doesn't work for me. Perhaps because I am using csh here and -c flag does not exist in my environment.

How can I access the return value of the command itself and not the xterm?

Solution

  • Use single-quotes to prevent your current shell from expanding symbols, e.g.,

    xterm -e 'MyCommand; echo $? > ./log.txt'
