+### jobs
+
+The current fish shell's background jobs, stopped or running, newest first. tv runs as a child process and cannot read the shell's job table, so `_jobs_bind` ([fish](/shell/fish#key-bindings)) writes it to a temp file named by `$TV_JOBS` and the source just `cat`s that file; opened any other way the list is empty. Entries are `%<id>  <state>  <command><TAB><id><TAB><pgid>`; <kbd>enter</kbd> prints the id and the binding runs `fg %<id>`.
+
+The preview finds the job's processes by process group (procps `ps -g` matches sessions, so it filters `ps -e -o pgid,pid`) and shows the first process's cwd and start time, then `ps --forest` with PID, STAT (`T` = stopped), elapsed time, CPU, RSS, and arguments. The preview script avoids `{`/`}` because tv would parse them as templates and leave `{split:…}` unexpanded.

+| <kbd>ctrl-d</kbd> | `kill` then `reload_source`: SIGTERM to the job's process group, then SIGCONT so a stopped job receives it. Once the group is gone (polled up to 1 s) the row is removed from `$TV_JOBS`, so the reloaded list drops it; a job that ignores SIGTERM stays listed. Fish reports the termination at the next prompt |
