as a file's @code{ctime}.
The inode change time represents the time when the file's meta-information
-last changed. One common example of this is when the permissions of a

file change. Changing the permissions doesn't access the file, so
the atime doesn't change, nor does it modify the file, so the mtime
doesn't change. Yet, something about the file itself has changed,
@dfn{success}. It can be used as a place holder in shell scripts
where a successful command is needed, although the shell built-in
command @code{:} (colon) may do the same thing faster.

you use @samp{true} in a script, you're probably using the built-in
