Subject: Check for presence of SHELL environment variable
X-Git-Url: https://git.xinqibao.xyz/st.git/commitdiff_plain/bafbba56cd5735c680676db2adf6f614ba61356f?ds=sidebyside;hp=bafbba56cd5735c680676db2adf6f614ba61356f

Check for presence of SHELL environment variable

- POSIX states the SHELL environment variable "... shall represent a
  pathname of the user's preferred command language interpreter." As
  such, st should check for its presence when deciding what shell to
  use; just as HOME can be defined to override one's passwd-defined home
  directory, a user should also be able to override their passwd-defined
  shell using the SHELL environment variable.
