= NAME =
is_on_target

= SYNOPSIS =
 * is_on_target <item> <varname> [<path>[:<path2>...]]

= DESCRIPTION =
The function is_on_target scans for the given filesystem item (file or directory) on the target device, and if found puts the absolute path
of the item into the indicated variable.

The optional 3rd argument specifies a list of places to search for
the item.  It is a colon-separated list of directory names.
If this argument is not specified, then the 'find' command is used
on the target to try to locate the item, by name, from the root of
the filesystem.

''Note that if the target filesystem is large, this operation
could take a long time.''

= EXAMPLES =
Here are some sample invocations:
{{{#!YellowBox
    is_on_target bc BC_PROGRAM /bin:/usr/bin:/usr/local/bin
    assert_define BC_PROGRAM
}}}

= ENVIRONMENT and ARGUMENTS =
 * $1 is the item to find in the remote filesystem
 * $2 is the name of the variable to set
 * $3 (optional) is a colon-separated path of directories to scan for this item in

= RETURN =
Returns non-zero on error.  If the item is found, the full path to
the item is returned as the value of the specified variable.
