tcsh: glob
Description
glob is like echo, but no \ (backslash) escapes are recognized and words are
delimited by null characters in the output. glob is useful for programs which wish to
use the shell to filename expand a list of words.

hashstat built-in command for tcsh: Print a statistic line on hash table
effectiveness
Format
hashstat
Description
hashstat prints a statistics line indicating how effective the internal hash table has
been at locating commands (and avoiding exec’s). An exec is attempted for each
component of the path where the hash function indicates a possible hit, and in each
component which does not begin with a / (forward slash).
z/OS systems have a vfork() command, however, tcsh is not compiled to use it.
Typically on machines without vfork, hashstat prints only the number and size of
hash buckets, but on z/OS systems, a hashstat print out would contain this:
> hashstat
> hashstat 512 hash buckets of 8 bits each

hup built-in command for tcsh: Run command so it exits on a hang-up
signal
Format
hup [command]
Description
With command, hup runs the command such that it will exit on a hangup signal and
arranges for the shell to send it a hangup signal when the shell exits. Commands
may set their own response to hangups, overriding hup. Without an argument
(allowed only in a shell script), hup causes the shell to exit on a hangup for the
remainder of the script. See “Signal handling” on page 652.

limit built-in command for tcsh: Limit consumption of processes
Format
limit [–h] [resource [maximum-use]]
Description
limit limits the consumption by the current process and each process it creates to
not individually exceed maximum-use on the specified resource. If no maximum-use
is given, then the current limit is printed; if no resource is given, then all limitations
