With the export built-in, the given name s are marked for automatic export to the environment of subsequently executed commands. If no arguments are given, variable names that have been marked for export during the current shell's exe- cution are listed. Function names are not exported. Multiword values are displayed as a parenthesized list. A space-separated list of words enclosed in parentheses.
Values are command and filename expanded before being assigned.
With no arguments, setenv displays all environment vari- ables. With both VAR and word arguments specified, setenv sets VAR to word , which must be either a single word or a quoted string. The most commonly used environment variables, USER, TERM, and PATH, are automati- cally imported to and exported from the csh variables user, term, and path. Use setenv if you need to change these variables. In addition, the shell sets the PWD environment variable from the csh variable cwd whenever the latter changes.
