Under bash, the declare or typeset keywords (they are exact synonyms) permit restricting the properties of variables. This is a very weak form typing available, and the declare/ typeset command is not available in version 1 of bash ... The switches that I know of are: -r readonly, and -i for integer ... I have not come across a -L equivalent. bash scripts use declare in preference to typeset usually.
