1732 # sl: ssh, but firsh rsync our bashrc and related files to a special
1733 # directory on the remote host if needed.
1735 # Some environment variables and files need to be setup for this to work
1736 # (mine are set at the beginning of this file)
1738 # SL_FILES_DIR: Environment variable. Path to folder which should at
1739 # least have a .bashrc file or symlink. This dir will be rsynced to ~ on
1740 # remote hosts (top level symlinks are resolved) unless the host already
1741 # has a $SL_FILES_DIR/.bashrc. In that case, we assume it is a host you
1742 # control and sync files to separately and already has the ~/.bashrc you
1743 # want. The remote bash will also take its .inputrc config from this
1744 # folder (default of not existing is fine). Mine looks like this:
1745 # https://iankelling.org/git/?p=distro-setup;a=tree;f=sl/.iank
1747 # SL_INFO_DIR: Environment variable. This folder stores info about what
1748 # we detected on the remote system and when we last synced. It will be created
1749 # if it does not exist. Sometimes you may want to forget about a
1750 # remote system, you can use sl --rsync, or the function for that slr
1753 # SL_TEST_CMD: Env var. Meant to be used to vary the files synced
1754 # depending on the remote host. Run this string on the remote host the
1755 # first time sl is run (or if we run slr). The result is passed to
1756 # SL_TEST_HOOK. For example,
1757 # export SL_TEST_CMD=". /etc/os-release ; echo \${VERSION//[^a-zA-Z0-9]/}"
1759 # SL_TEST_HOOK: Env var. It is run as $SL_TEST_HOOK. This can set
1760 # $SL_FILES_DIR to vary the files synced.
1762 # SL_RSYNC_ARGS: Env var. String of arguments passed to rsync. For
1763 # example to exclude files within a directory. Note, excluded
1764 # files wont be deleted on rsync, you can add --delete-excluded
1765 # to the rsync command if that is desired.
1767 # SL_SSH_ARGS: Env var. Default arguments passed to ssh.
1769 # For when ~/.bashrc is already customized on the remote server, you
1770 # might find it problematic that ~/.bashrc is sourced for ALL ssh
1771 # commands, even in scripts. This paragraph is all about that. bash
1772 # scripts dont source ~/.bashrc, but call ssh in scripts and you get
1773 # ~/.bashrc. You dont want this. .bashrc is meant for interactive shells
1774 # and if you customize it, probably has bugs from time to time. This is
1775 # bad. Here's how I fix it. I have a special condition to "return" in my
1776 # .bashrc for noninteractive ssh shells (copy that code). Then use this
1777 # function or similar that passes LC_USEBASHRC=t when sshing and I want
1778 # my bashrc. Also, I don't keep most of my bashrc in .bashrc, i source a
1779 # separate file because even if I return early on, the whole file gets
1780 # parsed which can fail if there is a syntax error.
1782 # Background on LC_USEBASHRC var (no need to read if you just want to
1783 # use this function): env variables sent across ssh are strictly
1784 # limited, but we get LC_* at least in debian based machines, so we
1785 # just make that * be something no normal program would use. Note, on
1786 # hosts that dont allow LC_* I start an inner shell with LC_USEBASHRC
1787 # set, and the inner shell also allows running a nondefault
1788 # .bashrc. This means the outer shell still ran the default .bashrc,
1789 # but that is the best we can do.
