1782 # Some environment variables and files need to be setup for this to work
1783 # (mine are set at the beginning of this file)
1785 # SL_FILES_DIR: Environment variable. Path to folder which should at
1786 # least have a .bashrc file or symlink. This dir will be rsynced to ~ on
1787 # remote hosts (top level symlinks are resolved) unless the host already
1788 # has a $SL_FILES_DIR/.bashrc. In that case, we assume it is a host you
1789 # control and sync files to separately and already has the ~/.bashrc you
1790 # want. The remote bash will also take its .inputrc config from this
1791 # folder (default of not existing is fine). Mine looks like this:
1792 # https://iankelling.org/git/?p=distro-setup;a=tree;f=sl/.iank
1794 # SL_INFO_DIR: Environment variable. This folder stores info about what
1795 # we detected on the remote system and when we last synced. It will be created
1796 # if it does not exist. Sometimes you may want to forget about a
1797 # remote system, you can use sl --rsync, or the function for that slr
1800 # SL_TEST_CMD: Env var. Meant to be used to vary the files synced
1801 # depending on the remote host. Run this string on the remote host the
1802 # first time sl is run (or if we run slr). The result is passed to
1803 # SL_TEST_HOOK. For example,
1804 # export SL_TEST_CMD=". /etc/os-release ; echo \${VERSION//[^a-zA-Z0-9]/}"
1806 # SL_TEST_HOOK: Env var. It is run as $SL_TEST_HOOK. This can set
1807 # $SL_FILES_DIR to vary the files synced.
1809 # SL_RSYNC_ARGS: Env var. String of arguments passed to rsync. For
1810 # example to exclude files within a directory. Note, excluded
1811 # files wont be deleted on rsync, you can add --delete-excluded
1812 # to the rsync command if that is desired.
1814 # SL_SSH_ARGS: Env var. Default arguments passed to ssh.
1816 # For when ~/.bashrc is already customized on the remote server, you
1817 # might find it problematic that ~/.bashrc is sourced for ALL ssh
1818 # commands, even in scripts. This paragraph is all about that. bash
1819 # scripts dont source ~/.bashrc, but call ssh in scripts and you get
1820 # ~/.bashrc. You dont want this. .bashrc is meant for interactive shells
1821 # and if you customize it, probably has bugs from time to time. This is
1822 # bad. Here's how I fix it. I have a special condition to "return" in my
1823 # .bashrc for noninteractive ssh shells (copy that code). Then use this
1824 # function or similar that passes LC_USEBASHRC=t when sshing and I want
1825 # my bashrc. Also, I don't keep most of my bashrc in .bashrc, i source a
1826 # separate file because even if I return early on, the whole file gets
1827 # parsed which can fail if there is a syntax error.
1829 # Background on LC_USEBASHRC var (no need to read if you just want to
1830 # use this function): env variables sent across ssh are strictly
1831 # limited, but we get LC_* at least in debian based machines, so we
1832 # just make that * be something no normal program would use. Note, on
1833 # hosts that dont allow LC_* I start an inner shell with LC_USEBASHRC
1834 # set, and the inner shell also allows running a nondefault
1835 # .bashrc. This means the outer shell still ran the default .bashrc,
1836 # but that is the best we can do.
