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
