# ct.sh <channel> [script-file] - run a bash script as ROOT inside the container (login shell),
# reading the script from the file or from stdin.  Generic form of the old c.sh/c2.sh/c3.sh.
#
#   printf '%s\n' 'ls -la /tmp/*.log' | bash ct.sh mychan
#   bash ct.sh mychan ./something.cmd
#
# How: the script is written to $ANL_DIR/<channel>.cmd, pushed to $DEV_TOOLS/<channel>.cmd together with
# a one-line <channel>.sh that does `droidspaces --name=<container> run bash -lc "$(cat <channel>.cmd)"`,
# and that runs under `su`.  Quoting through adb + su + droidspaces is thereby avoided entirely.
#
# Pick a channel name of your own: other sessions on the same phone use c, c2, c3, xd, xr, gbm...;
# writing to their channel files races with them.  CR characters are stripped (Windows checkouts).
# Inside, run user-side commands with `sudo -u <desktop user> env XDG_RUNTIME_DIR=/run/user/<uid> ...`.
# Never `pkill -f <word>` in a channel script: the `bash -lc "<script>"` process carries the whole
# script on its command line and kills itself.  Use `pkill -x <name>`.
