LLE10072 : Howto know which command will execute a certain command on the command line

Symptom:

You want to know for sure which command will execute exactly

Cause:

This is very important for your scripts and can lead to confusing errors

Solution:

You can use the which command to find out which executable will execute. which returns the pathnames of the files which would be executed in the current environment, had its arguments been  given  as  commands  in  a strictly  POSIX-conformant  shell.   It does this by searching the PATH for executable files matching the names of the arguments. e.g.

which man 

/usr/bin/man

Especially the command located in /usr/local/bin and /usr/local/sbin can be confusing.

If you need to know all possibilities and not only the command that will be executed you can use the -a parameter. e.g.

which -a man

/usr/bin/man
/usr/bin/X11/man
