```

Finally in `.bashrc` add
```bash
# creating alias for starting sync
alias startsync="/home/hpes/Videos/imp/scripts/sync_directories/screen/sync_bi.sh start"

# run command for starting sync
startsync

# creating alias for stopping sync
alias closesync="/home/hpes/Videos/imp/scripts/sync_directories/screen/sync_bi.sh stop"
```
