Question

User · Answer

First i had the approach from  jasonwryan but if you have more then 2 configs  it can get confusing   So i created an alias function   tmx          tmux   2  source-file   HOME  tmux  1 conf       In    tmux  i have multiple sessions for many uses  For example i work for different companies that have each another dev environment  So with the alias function above i can simply call  tmx company1 and load the config i need   Update  The purpose of   2  after the tmux command is  that you are able to pass additional tmux args

You can use tmux hooks to execute commands when a new session is created  Specifically  this is achieved using the session-created hook   For example  to split the screen three ways with htop running in the lower right you can add the following line to your    tmux conf file   set-hook -g session-created  split -h   split -v top    The advantage of this method is that you don t have to run tmux in any special way  i e   shell script or alias  to get the desired result  You can also combine this with tmux new-session -A -s mysession described in this other answer such that the hook commands are only run when you first create the session and not on subsequent attachments    This feature was added by d15d54c2c back in 2016  The first release to include it is is 2 4

There is a tmux plugin for this  Check out tmux-resurrect  Restore tmux environment after system restart  Tmux is great  except when you have to restart the computer  You lose all the running programs  working directories  pane layouts etc  There are helpful management tools out there  but they require initial configuration and continuous updates as your workflow evolves or you start new projects  tmux-resurrect saves all the little details from your tmux environment so it can be completely restored after a system restart  or when you feel like it   No configuration is required  You should feel like you never quit tmux   Or tmux-continuum  Features   continuous saving of tmux environment automatic tmux start when computer server is turned on automatic restore when tmux is started

I ve create this script  It does not need tmuxinator  ruby or others  It is just a bash script  configurable   A file named config should contains something like this   combo    combo    logs   cd  var log  clear  pwd   combo    home   cd    clear  pwd     and the bash code should be      bin bash  if   -r config    then     echo        echo  Loading custom file        config else       config dist fi  tmux start-server  window 0 windownumber -1  for i in    combo       do      if      window 2      0    then         name   i            windownumber         else         command   i      fi      if     combo 0         i      then         tmux new-session -d -s StarTmux -n    name       else         if      window 2      0    then             tmux new-window -tStarTmux  windownumber -n    name           fi     fi      if      window 2      1    then         tmux send-keys -tStarTmux  windownumber    command   C-m     fi        window     done  tmux select-window -tStarTmux 0 tmux attach-session -d -tStarTmux

You should specify it in your tmux config file     tmux conf   for example   new mocp neww mutt  new -d neww neww    opens one session with 2 windows with mocp launched in first and mutt in second  and another detached session with 3 empty windows

The plugin tmux-continuum will auto save your tmux session and load it the next time tmux starts  should be easier to setup than some of the custom script solutions here      Features          continuous saving of tmux environment    automatic tmux start when computer server is turned on    automatic restore when tmux is started      To save your session on demand you can use the tmux-resurrect plugin  tmux-resurrect is also required to run tmux-continuum     tmux-resurrect saves all the little details from your tmux environment   so it can be completely restored after a system restart  or when you   feel like it   No configuration is required  You should feel like you   never quit tmux

If you just want to split screen on 2 panes  say horizontally   you can run this command  no tmux or shell scripts required    tmux new-session    split-window -h      You screen will look like this    ks localhost                             ks localhost                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     10  0 ks localhost                      localhost localdomain  19 51 31-   -16

I was trying to create a complex grid of panes and had to deal with switching and splitting panes over and over again  Here are my learnings   tmux new-session      Gets you started with a new session  To split it horizontal or vertical use split-window -h or -v subsequently  like that   tmux new-session    split-window -v    split-window -h      Creates 3 panes  like this   ------------               ----------               ------------   To run commands in that panes  just add them with the send-keys  my-command  command and C-m which executes it   tmux new-session        send-keys  tail -f  var log monitor log  C-m        split-window -v        split-window -h        send-keys  top  C-m       And the resulting session should look like that   ------------    tail       ----------         top   ------------   Now I tried to again sub-divide the bottom left pane  so switching either back using last-pane  or in more complex windows  with the select-pane -t 1 where 1 is the number of the pane in order created starting with 0   tmux new-session        send-keys  tail -f  var log monitor log  C-m        split-window -v        split-window -h        send-keys  top  C-m        select-pane -t 1        split-window -v        send-keys  weechat  C-m      Does that  Basicaly knowing your way around with split-window and select-pane is all you need  It s also handy to pass with -p 75 a percentage size of the pane created by split-window to have more control over the size of the panes   tmux new-session        send-keys  tail -f  var log monitor log  C-m        split-window -v -p 75        split-window -h -p 30        send-keys  top  C-m        select-pane -t 1        split-window -v        send-keys  weechat  C-m      Which results in a session looking like that  ------------------        tail         ----------------               top    ----------          weechat          ------------------   Hope that helps tmux enthusiasts in the future

I just tried using all the ideas on this page and I didn t like any of them   I just wanted a solution that started tmux with a specific set of windows when my terminal opened   I also wanted it to be idempotent  i e  opening a new terminal window takes over the tmux session from the previous one   The above solutions often tend to open multiple tmux sessions and I want just one   First  I added this to my    bash profile   tmux start-server if    -z   TMUX     then   exec tmux attach -d -t default fi   then I added the following to my    tmux conf   new -s default -n emacs  usr local bin emacs neww -n shell  usr local bin bash neww -n shell  usr local bin bash selectw -t 1   now every time I start a terminal or start tmux or whatever  I either reattach to my existing desired setup  the session named default   or create a new session with that setup

smux py allows you to simply list the commands you want in each pane  prefixed with a line containing three dashes  Here s an example smux file that starts three panes  --- echo  quot This is pane 1  quot  --- cd  tmp git clone https   github com hq6 smux cd smux less smux py --- man tmux  If you put this in a file called Sample smux  you can then run the following to launch  pip3 install smux py smux py Sample smux  Full disclaimer  I am the author of smux py

You can source different sessions from your  tmux conf like so     initialize sessions bind S source-file    tmux session1  bind s source-file    tmux session2   And then format the sessions as you require    session1 new  -s SessionName -n WindowName Command neww -n foo bar foo splitw -v -p 50 -t 0 bar selectw -t 1  selectp -t 0   This would open 2 windows  the second of which would be named foo bar and would be split vertically in half  50   with foo running above bar  Focus would be in window 2  foo bar   top pane  foo     You can then start your preferred tmux session  in this case  session1  with PrefixShifts

Use tmuxinator - it allows you to have multiple sessions configured  and you can choose which one to launch at any given time  You can launch commands in particular windows or panes and give titles to windows  Here is an example use with developing Django applications   Sample config file        tmuxinator project name yml   you can make as many tabs as you wish     project name  Tmuxinator project root    code rails project socket name  foo   Not needed  Remove to use default socket rvm  1 9 2 rails project pre  sudo  etc rc d mysqld start tabs    - editor        layout  main-vertical       panes          - vim         -  empty  will just run plain bash         - top   - shell  git pull   - database  rails db   - server  rails s   - logs  tail -f logs development log   - console  rails c   - capistrano    - server  ssh me myhost   See the README at the above link for a full explanation
