llength(1t) Tcl Built-In Commands llength(1t) ______________________________________________________________________________ NAME llength - Count the number of elements in a list SYNOPSIS llength list ______________________________________________________________________________ DESCRIPTION Treats list as a list and returns a decimal string giving the number of elements in it. EXAMPLES The result is the number of elements: % llength {a b c d e} 5 % llength {a b c} 3 % llength {} 0 Elements are not guaranteed to be exactly words in a dictionary sense of course, especially when quoting is used: % llength {a b {c d} e} 4 % llength {a b { } c d e} 6 An empty list is not necessarily an empty string: % set var { }; puts "[string length $var],[llength $var]" 1,0 ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | runtime/tcl-8 | +---------------+------------------+ |Stability | Uncommitted | +---------------+------------------+ SEE ALSO list(n), lappend(n), lindex(n), linsert(n), lsearch(n), lset(n), lsort(n), lrange(n), lreplace(n) KEYWORDS element, list, length NOTES Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source- code-downloads.html.
