There are still a few scripts using the 'which' command to determine
either the full path or the mere existence of an executable.
Some of these scripts might run in minimal environments where 'which' is
not available due to dependency restriction. 'which' is also considered
unreliable for historical implementation details.
Use the POSIX defined [1] built-in 'command -v' instead to reduce
package dependencies and improve reliability.
