So here's my latest set up Every site I have is a profile on Termius like > hoodmaps .com I click it and immediately I'm in my server and I get dropped in a tmux session that's always tied to the corresponding site I wanna log in to To make this work I have this startup snippet in each site's Termius profile: > cd /srv/http/hoodmaps.com && tm (so /srv/http is where my sites are and then hoodmaps .com is the example site here, and "&& tm" is the important part here) Then in my ~/.bashrc file I added this (written by Claude Code) which defines the "tm" function, again all it does it just put me in the right tmux session based on the folder I'm in The result is I can switch without interruption from my laptop to phone in Termius with auto reconnecting sessions and usually I just have Claude Code open in each session to work Before I had to mess around with 1) not having smooth switching from laptop to phone, I'd have to use Claude Code's /resume for it, annoying, 2) having multiple sessions for same sites, gets messy and confusing fast, now it FORCES me into one session per site, this just works so well, I'm so fast, and each of my sites is just an open tab in Termius, I've never worked so structured and clean! Here is the code, maybe it helps somebody: # tmux session per folder. `tm` (no args) attaches to / creates a session # named after the current dir's basename. `tm name` overrides the name. # Works whether already inside tmux (uses switch-client) or outside it. tm() { command -v tmux >/dev/null 2>&1 || { echo "tmux not installed"; return 1; } local name="${1:-$(basename "$PWD")}" # tmux session names can't contain '.' or ':' — replace with '-' name="${name//./-}" name="${name//:/-}" if [ -n "$TMUX" ]; then tmux has-session -t "$name" 2>/dev/null || tmux new-session -d -s "$name" -c "$PWD" tmux switch-client -t "$name" else tmux attach -t "$name" 2>/dev/null || tmux new -s "$name" -c "$PWD" fi } # Auto-attach on interactive login: picks a session named after wherever # you land. Plain `ssh server` lands in $HOME → session "root". Use # `ssh server -t "cd /srv/sm.levels.io && bash -l"` to land in a site # folder → session "sm-levels-io". Skips inside tmux and non-interactive # shells so scp/rsync/scripted ssh keep working. if command -v tmux >/dev/null 2>&1 && [ -z "$TMUX" ] && [[ $- == *i* ]]; then tm fi
