which
Like the unix which utility.
Finds the first instance of a specified executable in the PATH
environment variable. Does not cache the results, so hash -r is not
needed when the PATH changes.
USAGE
1const which = require('which') 2 3// async usage 4// rejects if not found 5const resolved = await which('node') 6 7// if nothrow option is used, returns null if not found 8const resolvedOrNull = await which('node', { nothrow: true }) 9 10// sync usage 11// throws if not found 12const resolved = which.sync('node') 13 14// if nothrow option is used, returns null if not found 15const resolvedOrNull = which.sync('node', { nothrow: true }) 16 17// Pass options to override the PATH and PATHEXT environment vars. 18await which('node', { path: someOtherPath, pathExt: somePathExt })
CLI USAGE
Just like the BSD which(1) binary but using node-which.
usage: node-which [-as] program ...
You can learn more about why the binary is node-which and not which
here
OPTIONS
You may pass an options object as the second argument.
path: Use instead of thePATHenvironment variable.pathExt: Use instead of thePATHEXTenvironment variable.all: Return all matches, instead of just the first one. Note that this means the function returns an array of strings instead of a single string.
