SCP in LL5.4 post Upgrade with fix

[stellartk]

FWIW/FYI
- Upgraded LL 5.2 TO 5.4 VIA CLI GUI
- SCP would NOT transfer to remote hosts
- Would STOP at Welcome to Linux Lite 5.2 (GNU/Linux 5.4.0-96-generic x86_64)"
- Performed SCP -v option ; GENERATED ERROR  "debug1: Exit status -1 ""
- From another pc running LL 5.2, opened  .bashrc
- Noticed line 1 ===> [[ $- != *i* ]] && return <===        missing on 5.4 .bashrc
- added line in 5.4 .bashrc on line 1
- SCP working
