iewhich

Iewhich is a command-line utility designed to enhance the functionality of the traditional 'which' command in Unix-like operating systems. The 'which' command is used to locate the executable file associated with a given command in the user's PATH environment variable. However, 'which' has limitations, such as not being able to handle aliases or functions defined in shell scripts.

Iewhich addresses these limitations by providing additional features. It can identify the location of shell functions, aliases, and built-in commands, in addition to regular executables. This makes it a more comprehensive tool for users who need to understand the complete command resolution process in their shell environment.

The utility is particularly useful for system administrators and power users who frequently work in complex shell environments. By offering a more detailed view of command resolution, iewhich helps in troubleshooting issues related to command availability and execution paths.

Iewhich is typically implemented as a shell script or a small program written in a language like Python or Perl. It can be easily integrated into various Unix-like operating systems, including Linux and macOS, and is often included in system administration toolkits.

In summary, iewhich is an enhanced version of the 'which' command that provides a more comprehensive view of command resolution in shell environments. Its ability to handle aliases, functions, and built-in commands makes it a valuable tool for users who need detailed information about their command paths.
