The alias concept from csh was imported into Bourne Again Shell (bash) and the Korn shell (ksh). With shells that ...
The paper describes many features found in Bash.

KornShell (ksh): written by David Korn based on the Bourne shell sources [8] while working at Bell Labs; Public domain Korn ...
When a command line does not match a command or arguments directly, spell checking can automatically correct common typing mistakes (such as case sensitivity, missing letters). There are two approaches to this; the shell can either suggest probable corrections upon command invocation, or this can happen earlier as part of a completion or ...
