Checks that a dir's inode does not change; if it does, call action().

Copy a file.

Copy files in flist to destDir, stripping srcDir.

Check for UTF byte order mark; if present, seeks past it.

Case-insensitive search of 'dir' for all of 'entries'.

Computes size of dir and contents.

Perform case-insensitive search for file matching name (not a glob), under root, max depth maxdepth.

ForcePathCase ensures correct case for some dir or file target in basepath.

Return free space for FS containing dir, or -1 in the event of an error.

Returns human-readable free space (in MB) for FS containing given dir.

Crude check that given path is not a glob.

Returns true if given path is a dir and is empty.

IsMountpoint searchs for given dir in /proc/self/mountinfo, returns true if found.

checks for XZ header.

Checks for XZ header and stream option byte indicating sha256.

Recursively find all files matching pattern in dir; return them and their total size.

Create dir in root with given owner, group, and mode.

ReadConfigLines reads a config file at the given path.

return n bytes from beginning of file.

RecursiveCopy walks tree rooted at src, copies dir 'src' to a subdir of dest.

Renames old in same dir, using newPfx + random suffix (via os.TempFile).

Called from a goroutine, updates lcd with size of a file.

Converts a size in bytes to megabytes; returns string with suffix 'MB'.

WaitFor waits for a file to appear or times out.

WaitForChan is like WaitFor, but returns no later than when stop chan is closed.

WaitForDir waits for a dir to exist, and, if watchedIsMountpoint is true,waits for a fs to mount there.
