NAME<\/a> ______________________________________________________________________________<\/p>\n lindex \u2212 Retrieve an element from a list<\/p>\n lindex<\/b> list ?index …?<\/i> ______________________________________________________________________________<\/p>\n The lindex<\/b> command accepts a parameter, list<\/i>, which it treats as a Tcl list. It also accepts zero or more indices<\/i> into the list. The indices may be presented either consecutively on the command line, or grouped in a Tcl list and presented as a single argument.<\/p>\n If no indices are presented, the command takes the form:<\/p>\n lindex<\/b> list<\/i><\/p>\n or<\/p>\n lindex<\/b> list<\/i> {}<\/p>\n In this case, the return value of lindex<\/b> is simply the value of the list<\/i> parameter.<\/p>\n When presented with a single index, the lindex<\/b> command treats list<\/i> as a Tcl list and returns the index<\/i>\u2019th element from it (0 refers to the first element of the list). In extracting the element, lindex<\/b> observes the same rules concerning braces and quotes and backslashes as the Tcl command interpreter; however, variable substitution and command substitution do not occur. If index<\/i> is negative or greater than or equal to the number of elements in value<\/i>, then an empty string is returned. The interpretation of each simple index<\/i> value is the same as for the command string index<\/b>, supporting simple index arithmetic and indices relative to the end of the list.<\/p>\n If additional index<\/i> arguments are supplied, then each argument is used in turn to select an element from the previous indexing operation, allowing the script to select elements from sublists. The command,<\/p>\n lindex<\/b> $a 1 2 3<\/p>\n or<\/p>\n lindex<\/b> $a {1 2 3}<\/p>\n is synonymous with<\/p>\n lindex<\/b> [lindex<\/b> [lindex<\/b> $a 1] 2] 3<\/p>\n Lists can be indexed into from either end:<\/p>\n lindex<\/b> {a b c} 0 Lists or sequences of indices allow selection into lists of lists:<\/p>\n lindex<\/b> {a b c} List indices may also perform limited computation, adding or subtracting fixed amounts from other indices:<\/p>\n set idx 1 list(n), lappend(n), linsert(n), llength(n), lsearch(n), lset(n), lsort(n), lrange(n), lreplace(n), string(n)<\/p>\n element, index, list<\/p>\n lindex \u2212 Retrieve an element from a list <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3783,1],"tags":[2817,2635],"class_list":["post-6178","post","type-post","status-publish","format-standard","hentry","category-n-comandos-tcl-tk","category-sin-categoria","tag-lindex","tag-mann"],"gutentor_comment":0,"_links":{"self":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/6178","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/comments?post=6178"}],"version-history":[{"count":0,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/6178\/revisions"}],"wp:attachment":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/media?parent=6178"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/categories?post=6178"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/tags?post=6178"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
