However if I open a random file, I never want that file in the last directory window as it's unrelated. To do this I wrote a simple bash function: # subl: wrapper that opens files in a new window, and reuses the window # for directories subl() { local args=() opts=() for a in "$@"; do if [[ "$a" == -* ]]; then opts+=("$a") else args+=("$a") fi done # No path argument means the current directory [[ ${#args[@]} -eq 0 ]] && args=(.) if [[ ${#args[@]} -eq 1 && -d "${args[0]}" ]]; then # Single directory: open in same window command subl "${opts[@]}" "${args[0]}" else # File(s): so open in a new window command subl -n "${opts[@]}" "${args[@]}" fi } Firstly we determine which parameters on the command line are arguments and…
