I have an alias in .bashrc like this:

alias ylog = "yarn logs -applicationId"

This works well when I do ylog application_123.

Sometimes, my job names come in the form of job_123 instead of application_123 and in order to get ylog I need to manually replace the text "job" by "application" in my command line.

Is it possible to improve the alias so that the following happens:

  • ylog job_123 resolves to ylog application_123
  • ylog application_123 resolves to ylog application_123

Bash does not allow parameters in aliases, so you need to define and use a function, e.g.:

ylog() {
    yarn logs -applicationId "${1/#job_/application_}"
}
