login-shell | SSH login display script

< and > are not arguments to your command (in this case bsub), but are instructions to the shell about where stdin or stdout (respectively) should be directed before that command is started.

Thus, the appropriate replacement is to specify this redirection with a separate argument to Popen:

As you are using /etc/profile, i am assuming that you are looking to do this only for login sessions of shell (zsh).

That's because zsh by default does not read /etc/profile when starting a login shell. For setting any global parameter for only login shells, use the file /etc/zsh/zprofile.

For setting something applicable on any sort of invocation, use /etc/zsh/zshenv instead. The typical/generic order is zshenv > zprofile > zshrc > zlogin (depending on invocation and availability).

Needless to say, for any user specific parameter you should use the user specific .zprofile i.e. ~/.zprofile instead.

Notes:

• If you are looking to do this for any interactive shell session, use .zshrc (/etc/zshrc or ~/.zshrc)

• If you are looking at using a common /etc/profile (or similar), source (.) /etc/profile from the relevant file for zsh.
