1440 # has a $SL_FILES_DIR/.bashrc. In that case, we assume it is a host you
1441 # control and sync files to separately and already has the ~/.bashrc you
1442 # want. The remote bash will also take its .inputrc config from this
1443 # folder (default of not existing is fine). Mine looks like this:
1444 # https://iankelling.org/git/?p=distro-setup;a=tree;f=sl/.iank
1446 # SL_INFO_DIR: Environment variable. This folder stores info about what
1447 # we detected on the remote system and when we last synced. It will be created
1448 # if it does not exist. Sometimes you may want to forget about a
1449 # remote system, you can use sl --rsync, or the function for that slr
1452 # SL_TEST_CMD: Env var. Meant to be used to vary the files synced
1453 # depending on the remote host. Run this string on the remote host the
1454 # first time sl is run (or if we run slr). The result is passed to
1455 # SL_TEST_HOOK. For example,
1456 # export SL_TEST_CMD=". /etc/os-release ; echo \${VERSION//[^a-zA-Z0-9]/}"
1458 # SL_TEST_HOOK: Env var. It is run as $SL_TEST_HOOK. This can set
1459 # $SL_FILES_DIR to vary the files synced.
1461 # SL_RSYNC_ARGS: Env var. String of arguments passed to rsync. For
1462 # example to exclude files within a directory. Note, excluded
1463 # files wont be deleted on rsync, you can add --delete-excluded
1464 # to the rsync command if that is desired.
1466 # SL_SSH_ARGS: Env var. Default arguments passed to ssh.
1468 # For when ~/.bashrc is already customized on the remote server, you
1469 # might find it problematic that ~/.bashrc is sourced for ALL ssh
1470 # commands, even in scripts. This paragraph is all about that. bash
1471 # scripts dont source ~/.bashrc, but call ssh in scripts and you get
1472 # ~/.bashrc. You dont want this. .bashrc is meant for interactive shells
1473 # and if you customize it, probably has bugs from time to time. This is
1474 # bad. Here's how I fix it. I have a special condition to "return" in my
1475 # .bashrc for noninteractive ssh shells (copy that code). Then use this
1476 # function or similar that passes LC_USEBASHRC=t when sshing and I want
1477 # my bashrc. Also, I don't keep most of my bashrc in .bashrc, i source a
1478 # separate file because even if I return early on, the whole file gets
1479 # parsed which can fail if there is a syntax error.
1481 # Background on LC_USEBASHRC var (no need to read if you just want to
1482 # use this function): env variables sent across ssh are strictly
1483 # limited, but we get LC_* at least in debian based machines, so we
1484 # just make that * be something no normal program would use. Note, on
1485 # hosts that dont allow LC_* I start an inner shell with LC_USEBASHRC
1486 # set, and the inner shell also allows running a nondefault
1487 # .bashrc. This means the outer shell still ran the default .bashrc,
1488 # but that is the best we can do.
