Perl 5 version 8.7 documentation

chdir

  • chdir EXPR

    Changes the working directory to EXPR, if possible. If EXPR is omitted, changes to the directory specified by $ENV{HOME} , if set; if not, changes to the directory specified by $ENV{LOGDIR} . (Under VMS, the variable $ENV{SYS$LOGIN} is also checked, and used if it is set.) If neither is set, chdir does nothing. It returns true upon success, false otherwise. See the example under die.
