I was reading an article about fish at http://arstechnica.com/information-technology/2005/12/linux-20051218/2/ which has:
Most other Unix shells include built-in implementations of common commands like echo, kill, printf, pwd, time, and test. These internal implementations are usually slightly incompatible with the standard Unix tools they replace, making portability an even bigger hurdle. Making more and more commands a part of the shell also has stability implications, since a bug in the implementation of a command risks to crash the entire shell instead of only crashing a separate process. Also http://fishshell.com/docs/current/index.html has: To avoid code duplication, and to avoid the confusion of subtly differing versions of the same command, fish generally only implements builtins for actions which cannot be performed by a regular command. However: $ type echo printf pwd test echo is a builtin printf is a builtin pwd is a builtin test is a builtin I wonder why these commands were made built-in. ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
