Expressions

This section has been split up into subsections based upon functionality, loosely based upon the Perl Reference Guide by Johan Vromans. This is a departure from the original Perl manual, which should simplify on-line browsing. If you have problems with this organization, blame me (rgs@cs.cmu.edu) rather than Larry.

Expression types:

  • Flow control operations
  • Operators (including File Test operators)
  • Arithmetic functions
  • Conversion functions
  • String functions
  • Array and list functions
  • File operations
  • Directory reading
  • I/O operations
  • Search and modification operations
  • System interaction routines
  • IPC and Networking operations
  • Miscellaneous operations
  • System information
