RWC(1)                      General Commands Manual                     RWC(1)

NAME
     rwc – report when changed

SYNOPSIS
     rwc [-0d] [path ...]

DESCRIPTION
     rwc takes a list of files or directories, watches them using inotify(7),
     and prints each file name when it changed.  If path is a single dash
     (‘-’) or absent, rwc reads file names from the standard input.

     Watching a directory will result in watching all changes to files which
     resides directly in that directory.

     The options are as follows:

     -0      Read input filenames seperated by NUL bytes.  Likewise, output
             filenames seperated by NUL bytes.

     -d      Also detect file deletion.  In this case, deleted files are
             prefixed by ‘- ’ (that is, a dash and a space).

EXIT STATUS
     The rwc utility exits 0 on success, and >0 if an error occurs.

SEE ALSO
     entr(1), inotifywatch(1), wendy(1)

CAVEATS
     rwc is limited by some restrictions of inotify(7).  You can only watch
     files and directories you can read, and the amount of inotify descriptors
     is limited.  Watching directories is not recursive.

     rwc only uses one watch descriptor per directory, and filters file names
     itself.  This allows tracking files which get safely written by unlink(2)
     and rename(2), and also watching files which don't exist yet.

     Many tools like to create temporary files in their working directory,
     which may distort the output.
