'''info procs''' ''?pattern?''

If ''pattern'' isn't specified, returns a list of all the names of [Tcl procedure]s in the current namespace. If ''pattern'' is specified, only those procedure names in the current namespace matching ''pattern'' are returned. Matching is determined using the same rules as for [string match].

[RCN] - Why is exit not listed in [info procs]?  How come renaming exit will not make it visible in [info procs]?

======
puts "PROCS BEFORE: [lsort [info procs]]"

rename exit __super_exit
rename unknown __super_unknown
proc exit {{code 0}} {
    puts "Why are you leaving me :-("
    __super_exit $code
}

puts "PROCS AFTER: [lsort [info procs]]"
exit
======

The above code outputs:
======
PROCS BEFORE: auto_execok auto_import auto_load auto_load_index auto_qualify tclLog unknown
PROCS AFTER: __super_unknown auto_execok auto_import auto_load auto_load_index auto_qualify exit tclLog
Why are you leaving me :-(
======
