2015-12-17 For a long time, I used `which' to determine if a command is available. Back then -- I remember -- I searched for the best way to check this, and `which' appeared to be the best way. Now, ini- tiated by a discussion with Yannic, he pointed me to a recommen- dation to use `command -v'. [0] It seems to be the way to choose (for POSIX scripts). [1] I would like to dig deeper into this topic, because POSIX does not necessarily mean most portable.
