For an interactive session via SSH on a Linux cluster in Rstudio, it is very easy to accidentally execute the keyboard shortcut for "run in terminal" when commands are highlighted in Rstudio console. This results in behavior such as

> library

or

Var1>Var2

being executed in terminal, which creates a library or Var2 file in the remote working directory if the terminal is logged in at the bash prompt.

In a worst case scenario this would result in overwriting files in the remote working directory.

I would like to disable ">" in these sessions, but I am not sure how to do this.

  Redirection characters are fundamental to Linux shells and can't be changed. You should look at whether you can change the Rstudio prompt to something less drastic if accidentally copied. If you can't, you'll just need to take more care.

> is not a command but an operator, so you can't alias it. But you can disable overwriting files with the noclobber option. Just run set -C or set -o noclobber (or add them to your ~/.bashrc)

The noclobber option is available to avoid overwriting existing files with output redirection (see The Set Builtin). The ‘>|’ redirection operator may be used to override noclobber.
