find . -name H* -exec ls -l {} \; executes the command ls -l on each individual file.
find . -name H* | xargs ls -l constructs an argument list from the output of the find commend and passes it to ls.
consider if the ouput of the find command produced:
H1
H2
H3
the first command would execute
ls -l H1
ls -l H2
ls -l H3
but the second would execute
ls -l H1 H2 H3

find(n) [incr Tcl] find(n)
NAME
find - search for classes and objects
SYNOPSIS
find option ?arg arg ...?
DESCRIPTION
The find command is used to find classes and objects that are available in the current interpreter. Classes and objects are reported first
in the active namespace, then in all other namespaces in the interpreter.
The option argument determines what action is carried out by the command. The legal options (which may be abbreviated) are:
find classes ?pattern?
Returns a list of [incr Tcl] classes. Classes in the current namespace are listed first, followed by classes in all other names-
paces in the interpreter. If the optional pattern is specified, then the reported names are compared using the rules of the "string
match" command, and only matching names are reported.
If a class resides in the current namespace context, this command reports its simple name--without any qualifiers. However, if the
pattern contains :: qualifiers, or if the class resides in another context, this command reports its fully-qualified name. There-
fore, you can use the following command to obtain a list where all names are fully-qualified: find classes ::*
find objects ?pattern? ?-class className? ?-isa className?
Returns a list of [incr Tcl] objects. Objects in the current namespace are listed first, followed by objects in all other names-
paces in the interpreter. If the optional pattern is specified, then the reported names are compared using the rules of the "string
match" command, and only matching names are reported. If the optional "-class" parameter is specified, this list is restricted to
objects whose most-specific class is className. If the optional "-isa" parameter is specified, this list is further restricted to
objects having the given className anywhere in their heritage.
If an object resides in the current namespace context, this command reports its simple name--without any qualifiers. However, if
the pattern contains :: qualifiers, or if the object resides in another context, this command reports its fully-qualified name.
Therefore, you can use the following command to obtain a list where all names are fully-qualified: find objects ::*
